Chocolate pistachio swirls

Time for more fun with croissant dough! Thinking along the lines of pain au chocolat , how about using the classic chocolate batons in smaller pieces to create a chocolate pistachio swirl? Sure thing!

I’ve been using Callebaut’s chocolate baking sticks ever since my Paris internship days at Pascal Pinaud’s pâtisserie on rue Monge in the 5th arr. The box in the shop looked EXACTLY like this and here I am 13 years later still buying the same brand. They’re delicious and hold up well during baking - the only problem is that Steve likes to snitch a couple every day for that oh so needed chocolate fix.

I love making petite pain au chocolat with my basic croissant dough. Just the right size for a treat along side one’s morning coffee.

For this project I took a slightly different approach. I had a full batch of dough on hand but, since I wanted to bake some straight-up all butter croissants for the freezer (croissant aux amandes here we come!), I used a half batch for those and the other for my choco-pistachio swirls.

I made a pistachio version of crème d’amandes by replacing the almond flour with toasted and ground pistachios. Blend butter and sugar, add in the ground pistachios, blend in egg and a bit of flour and you’re ready.

I prepped my muffin tins by buttering and coating with raw sugar.

I spent a few minutes plotting the size to which I wanted to roll the dough out as well as the width of each spiral. Turns out I used 1/3 portions (~1 inch wide pieces) of the chocolate batons to create my spirals.

I planned 9 swirls from a half batch of dough. Roll the dough out to ~ 9 inches wide and ~ 12 inches high. Spread a layer of pistachio cream over the dough and place 4 rows of the 1” baton pieces across the dough, spacing the rows about 3 inches apart as seen below.

Cut one inch strips, roll them up and tuck them cut side up in the prepared muffin tins.

Cover the pan lightly with plastic wrap and let the spirals rise about 45 minutes. You should appreciate some poof and greater prominence of the laminations.

About 20-30 minutes before baking heat the oven to 375ºF.

Bake approximately 20-25 minutes until golden brown and the pistachio cream is set. I typically bake 10 minutes, rotate my pan and, depending on the degree of browning, I may reduce my oven temp to 350ºF to finish the process.

I find that when baking these in a muffin tin, even when the visible portions of the swirls look nicely browned, once I pop them out of the pan there can still be paleness to the sides and bottoms. If so, I transfer the swirls (OUT of the tin) onto a parchment lined sheet pan and put them back in the oven at 325ºF for another 5-10 minutes to finish off the baking and have a nicely golden end result. It’s a bit more fuss but it does the trick.

Another way to approach this is to use buttered 80 mm open rings instead of a muffin tin or simply space the pastries an inch and a half or so apart on a parchment lined sheet pan and bake them unfettered by any type of form. They’ll probably unfurl a bit as they expand but will be “held” by their neighbors.

Once cooled (or even when still a bit warm!) enjoy with a fresh cup of coffee or your favorite tea. No fancy plated shot here - just go for it!

Flaky, buttery, pistachio-y with just the right balance of chocolate. Good and good for ya as Steve loves to say!

Stay home and happy baking! We’ll get through this yet folks.
