Rainbow Chromatic/CMYK Croissants! Or, Ally baking.

I actually started these last Sunday after my croissant and brioche class (hi everyone who came from that!), the day of the New York Pride parade. But I didn't actually have time to finish them until this Saturday, the very last day of Pride Month -- skating in just under the wire to support the LGBTQIA+ community, and finally get an idea out of my head and into the world.

UPDATED with more pictures -- scroll down!

You've probably seen this London hotel's rainbow croissants, but I've never seen a recipe or technique that goes with it. And I wanted to make the colors run parallel to the croissant's sections, rather than perpendicular, so each one would be more likely to display all the colors side by side.

I started with a batch of croissant dough, made the usual way with 3 single folds. 

While that rested, I made a small batch (approximately 300 g of flour) of "dead dough" -- the detrempe without the yeast. I used all milk for extensibility, and all-purpose flour because I knew I'd be handling it a lot just to mix the colors in. I divided this dough into three pieces and colored one with egg yellow, one with sky blue, and one with rose pink/red red. (Gel colors rather then liquid, so the dough didn't get too soft.) I then took about a third from each and mixed them with each other to create green, orange and purple/violet doughs. Wrapped and chilled to relax the considerable gluten developed.

Cut to Saturday! Little 2 helped me -- actually she bugged me to make them even though I said it was too hot. I'm glad she did though, I would not have persevered if not for her!

 I figured out that my best bet for making the color strips very even was using a pasta machine. So each color was run through with a bit of flour to make a piece with consistent thickness.

I handcut strips and stacked them, slightly overlapping, to make the rainbow. (You'll see I tried a few different sequences of colors) 

Going through the pasta roller a few times to make the whole piece thinner. I stopped on setting 4. 

These went into the fridge.

Rolled out half of the plain dough, dabbed it with water to make the color panels stick.

Rolled over a few times to make sure they adhered well, then chilled a good while. I had to cut this piece in half to fit it in the fridge...

  
Rolled out again, to about 10 inches wide, then cut in triangles. Notice the different sequences...

 rolled into the familiar croissant shape, and set onto silpat-lined pans to proof.

I use a half sheet plastic cover to prevent them from drying out but also so nothing sticks to the soft dough and chances ripping the surface. 

 

I decided not to eggwash them so they retained more of their color instead of being yellow-tinged, but of course if it matters to you to be authentic you can eggwash them.. or brush them with glaze after baking.

Et voila -- Croissants arc en ciel! Happy Pride everyone... We are chuffed that these worked as well as they did. Next time I will try to make the orange truer in tone, make the color dough sheets thinner if I can, and pick a cooler/less humid day to do them!

UPDATE: We made them again ! 

This time I didn't use a pasta machine and just laid the colors out in wide panels striped parallel to the long sides of the rectangle -- i got a few that were each color, and a few i cut perpendicular to get as many colors on there as I could. It was much easier but each croissant was not as rainbow-y. I also used a much truer-toned blue color so it came out brighter in the baked finish. I think the happy medium is between the two tho!
