Swiss meringue buttercream

Ciao everyone! It took me a bit of time to get this post together, but here it is at last. You’d think with all the extra time on our hands during our staying at home (11 weeks and counting), I’d have knocked this baby out in a few days. I decided to take some extra time to add some recipes for some base components that are great ones to have in your baking armamentarium, and you’ll find links for those throughout the post.

Remember - you can also go directly to my recipe page for a list of base recipes with links to their PDFs and in some cases to blog posts on that particular topic.

Let’s go for it.

Never a big sweet frosting lover, I usually turn to a simple lightly sweetened Chantilly cream, a flavored whipped mascarpone or a basic ganache to give my petite cakes a swirl of panache. Buuuuuuuuut . . . . . . in recent years I’ve become a huge fan of SMBC. So light, airy, buttery and not cloyingly sweet, it’s rife with flavor possibilities. Let’s take a look at just a few and see what you can create to tickle your taste buds.

The beauty of this process is that the base remains the same - egg white, sugar, butter - with flavor added once all the butter is incorporated. Depending on what I plan to use the buttercream for, I’ll do a full batch as a single flavor or divide it in two and create two different flavors. The half batches work well for my small portion cake projects in which a nice swirl or dollop per un petit gâteau is all that’s needed. How efficient is that?

It’s the perfect make-ahead component too since it holds well in the fridge for several days and in the freezer for months. Just remember to thaw and bring it completely to room temperature before rewhipping and using for its intended purpose. It’s most commonly used for filling and decorating layer cakes, garnishing petite cakes or for sandwiching French macarons. A squiggle on an èclair or choux puff might not be bad either!

I reviewed a number of recipes from different sources and found many variants in terms of sugar to egg white ratio (anywhere from 1:1 up to 2:1) as well as differences in the amount of butter added e.g. when using 6 large whites, the butter quantity can range from 340 g / 12 ounces up to a full 456 g / one pound or even more!

Here’s my full batch base recipe (includes flavor variations!) which makes about 4.5 cups of buttercream - generally plenty for a 2-layer eight or nine inch round cake with leftovers for decorating, or just the ticket for some dozens of small treats. And remember - you can freeze the leftovers!

Getting ready to go!

On the day you want to make your SMBC, plan ahead and weigh out 370 g unsalted butter and cut it into 1/2 to 1 inch cubes. The butter needs to be at room temperature before adding it to the meringue!

Have your flavor ingredients ready to go too - from a pinch up to 1/4 teaspoon of salt to taste, 2 teaspoons vanilla (or other extracts) plus your chosen additions like caramel, fruit purée, melted/cooled yet liquid chocolate or lemon curd.

For the meringue place 6 large egg whites and 300 g sugar in a bowl over a steaming bain marie whisking constantly until the mixture reaches a temperature of anywhere from 145-155ºF. Transfer the mixture to the bowl of a stand mixer fitted with the whisk and beat on high until completely cool and marshmallow-y. I plan on a good 10 minutes for that.

Realize that the bottom of the mixing bowl may still feel a tad warm to the touch due to the heat of mixing. I test the meringue by putting a dab on my wrist - if it feels cool, I start adding the butter. You want to avoid adding it too early or you’ll end up with a soupy mess.

Add the butter several pieces at a time, blending completely after each addition. The mixture should thicken and become smooth and creamy by the time all the butter has been added. If it’s too loose, pop it into the fridge or freezer to firm it up and then rewhip.

Butter added - just waiting for flavor additions

When incorporating flavor components, they should be at room temperature, added slowly and blended on medium low with the whisk attachment to keep the buttercream from separating. Then scrape down and give it a final high speed whisking for a couple of minutes. Some folks switch to the paddle to give it a final fluffing up.

For a full batch of apple cider caramel blend in 1/4 teaspoon salt, 1 cup caramel sauce with 2 tablespoons boiled cider (available from King Arthur Flour) and 1 teaspoon vanilla extract or vanilla bean paste.

For white chocolate mocha have ready 170 g white chocolate, melted and cooled yet still liquid, plus 2 tablespoons instant espresso powder dissolved in 2 tablespoon hot water and cooled. Blend it in. Yum.

Oh man - yes I know this isn’t gelato but these images remind me of those mounds of creamy, cold goodness on display in all the gelaterias in Italy!

In addition to the two above (let’s call them richer flavors), I also went for the lighter, springier choices of lemon, mixed berry and honey orange. You can find details on the flavor additions here.

Now what exactly might I do with all this buttercream?? Small cakes of course!

First a quick word on piping tips. Just three tip shapes - round, star and French star - can create a bevy of designs for you. For years I’ve relied on my round and basic star tips (closed or more open like the one in the rear) to pipe the simple designs I prefer, but the French star - oh my. It has finer spacing which creates more of a seashell or tighter spiral look. I LOVE it. The only one I have is the one you see below, but I think a couple more sizes would do me just fine. Yup.

BTW just so you have a sense of size, the round tips range from 6 mm at the bottom of the image up to 12 mm (~1/2 inch) at the top.

I chose pecan cakes for the apple cider caramel SMBC, baking them in petite tinned steel brioche tins. NOTE: it’s very important to butter the tins thoroughly and pop the cakes out within a few minutes of coming out of the oven to avoid sticking. One could also use mini muffin tins like I did in a previous post where you’ll find the pecan cake recipe. Silicone molds would also work well although I think the cakes brown and crisp better in metal molds.

My small round tip served nicely to pipe a daisy like design to compliment the fluted ridges of the cakes. Pretty simple stuff.

For the white chocolate mocha SMBC a classic moelleux chocolat seemed just right, baked in one of my favorite square savarin silicone molds. The French star tip yields a lovely scallop like swirl. Those are some Valrhona dark chocolate crunchy pearls on top. Delicious.

The lemon cake is essentially financier batter to which lemon zest has been added. I baked these in mini-muffin silicone molds. So simple and nice.

Lemon on citrus financier

Since I made a batch of lemon curd to add to the lemon buttercream, I also used it to create a center flavor burst in the cake before topping with the final flourish. Using a round tip I cut out a core piece (for snacking of course), filled it with the curd and finished it off with a star tip swirl.

For the mixed berry use your favorite base muffin recipe and fold in an assortment of berries like blue, red and black. I generally avoid adding fresh strawberries to cakes or muffins due to their water content and mushiness after baking. Once again a star tip provides the luscious ridges. Create different looks as you swirl, twist and lift your tip.

For the honey orange SMBC I again used my base financier batter, replacing 1/2 the almond flour with finely ground pistachios and adding orange zest for a lovely citrus touch. Similar to the lemon cakes above, I used my favorite mini-muffin silicone mold for the cakes and the star tip swirl for the top flourish with a few pistachios tucked in the center for a tasty treat.

Honey orange on orange pistachio financier

For a different look I used another favorite ingot rectangular silicone mold which gives me a linear canvas for the buttercream using the French star tip. Same financier, more orange zest in the buttercream for a deeper orange color and a ridge of scallops or stars on top. Remember it’s all about how you twist, swirl and lift! Candied pistachios add just the right crunch. So deeeelicous!

Have fun creating your own treats with luscious buttercream the Swiss way!

As spring moves into summer do your best to keep a positive outlook, stay safe and healthy. That’s what counts.

This year's Thanksgiving tarts

Thanksgiving is fast approaching and now’s the time to decide what you’d like on your holiday dessert table!

This year I’m offering pumpkin custard with sesame crunch, pecan caramel chocolate truffle and apple cranberry with brown sugar crumble in both 9-inch and my “sharing” 5.5 inch size (seen in the photos above and below) for those of you who might prefer petite portions or are hosting or joining a smaller group for the holiday this year.

Let’s take a look at how these babies are put together, shall we? BTW - even though the images depict smaller tarts, the discussion is for making standard 9 inch tarts.

First up is pumpkin custard. Use your favorite pate sucrée recipe and add about 30 g toasted sesame seeds at the end of the dough prep. Blind bake the crust at 350ºF and set it aside while preparing the filling. Note: tart dough recipe is enough for two 9” tarts - wrap and freeze any extra for another time.

Reduce the oven temperature to 325ºF.

Make your favorite crème pâtissiére, adding 1-2 teaspoons or so of pumpkin pie spice mix (I use my own made-up mixture of spices) to the milk base. At the end of cooking blend in 1 cup pure pumpkin purée, 4 tablespoons of butter and two teaspoons vanilla extract. This base is more than enough for one 9 inch tart but you can use leftovers to make a bunch of mini-tarts or fill cream puffs. You can even divide what’s left into ramekins and bake them in a water bath for a lovely pumpkin custard for after the holiday.

Fill the blind baked tart shell with the warm pastry cream, just barely shy of the rim and bake for about 20 minutes until set with a hint of a jiggle in the center. I did several test batch sizes as you can see below.

Let cool then store covered in the fridge until ready to serve. In my case I garnished with whipped honey mascarpone cream and a sprinkling of sesame crunch. For a slightly different approach, change out the sesame seeds in the tart dough with toasted, finely chopped hazelnuts, almonds or pecans and use the same nut as a simple garnish with lightly sweetened whipped cream. Or simply leave out any dough additions and create your own version of topping.

Next up - pecan caramel chocolate truffle tart. And remember - this is for a nine inch tart. The approach is much the same: blind baked pate sucrée, cooled and waiting on the sidelines. For a chocolate crust, just add 30 g (~1/3 cup) unsweetened cocoa powder to the flour in the recipe.

Toast 100 g/scant cup pecans and either leave the halves whole or break them up coarsely. Blend them with a scant 2/3 cup caramel sauce (I make my own, although you can use a good quality purchased product from your local supermarket or specialty food shop).

Place 85 g dark chocolate (I use Guittard 61% discs) and 21 g unsalted butter in a heat proof bowl. In a separate heat proof container (I use a pyrex measuring cup) bring 120 ml heavy cream to a boil. Pour over the chocolate/butter and blend gently until smooth. Blend in 3/4 teaspoon pure vanilla extract. Note: double or triple your recipe to have more ganache on hand for your next truffle tart project!

Layer the nut caramel mixture in the bottom of the baked shell. Once again I made some small trial versions - for taste testing, don’t ya know?!

Pour the ganache over - start slowly to let it nestle into all the nooks and crannies and continue pouring until it’s to the rim edge. Some bubbles will invariable pop up to the surface - just pop ‘em with the tip of a paring knife.

Leave at room temperature until the ganache has set and cooled. If you put it in the fridge before that, there’s a greater chance that beads of moisture will form on the surface - you don’t want that! Once cooled you can go ahead with any garnish or cover/refrigerate and garnish later.

I top mine with chocolate shortbread cookie crumbs, a light dusting of confectioner’s sugar and a few pecans in the center. Pull the tart from the fridge 30-60 minutes before serving to let it temper and bring out the flavors more fully. Feel free to add a dollop of lightly whipped cream atop each portion.

Last but not least - apple cranberry! A straight forward pâte brisée dough filled with a mixture of lightly sweetened sliced apples and dried cranberries and topped with a brown sugar crumble.

Heat the oven to 425ºF.

I typically line my tart rings, fork-prick the dough and hold them in the freezer while preparing the fruit. For a nine inch tart I plump 100 g dried cranberries in warm apple cider for 20 minutes or so while I peel, core, halve and thinly slice 4-4.5 cups of Jonagold apples (another good mix is Macintosh and Granny Smith). Drain and paper towel dry the cranberries and mix the fruit with a squeeze of lemon juice, 1/4 cup sugar (use brown if you’d like) and 2 tablespoons of flour. Then I mound the fruit into the lined ring. In this case Mr. Steve had reduced down a bunch of apple cider for me, creating a delicious apple cider caramel. I drizzled some of that on the fruit once the lined ring was filled. Yummy stuff.

You might notice the scrap of rolled out dough on the sheet pan - I bake one every now and again just to see how the crust tastes au naturel. (In case you’re wondering, it was flaky, buttery and melt-in-your-mouth good.)

Top with a standard crumble mixture of equal weights flour, brown sugar (light or dark is fine) and diced butter and cover the fruit with the mixture. Not a very thorough covering job on those small tarts, eh? As I’ve mentioned in previous posts over time, I like to make a bunch of crumble, bag it up and stash in the freezer where it’s at the ready to be used.

Bake on the bottom rack for 10 minutes then reduce oven temp to 400 and move up to the middle rack. Give it another 10 minutes then ratchet down to 375 and continue baking for another 10-20 minutes (all ovens are different so pay attention!) until the crumble has browned and you see some bubbling around the edges. Cool a bit and serve slightly warm or at room temp with your favorite ice cream or whipped cream. Yippee!

And there you have it! A delightful trio of seasonal tarts just waiting for the Thanksgiving table. Have a calm and peaceful holiday everyone.

Meanwhile here in west Michigan there are lots of rustling leaves along the pathways and the burning bushes are still burning brightly, even though many trees are now bare. Tis the season - and we may even see our first snow this weekend. Oh boy, oh boy!
