I was trying to make croissants for the first time, following a recipe that said the butter block should be 'pliable but cold'. My kitchen was a bit warm, maybe 72 degrees, and every time I tried to roll it into the dough, the butter would either melt into a greasy mess or crack into sharp pieces. I must have tried six times, starting over with new butter each time. I even put a marble slab in the freezer for an hour to use as a surface. The whole process, which the recipe said would take 20 minutes for the lamination prep, ended up taking me almost three hours. I finally got it right by chilling the dough for 15 minutes between every single fold, not just every other. Has anyone else found a better trick for keeping butter at that perfect, bendy temperature?
That Cook's Illustrated test from last year said European butter is often too cold straight from the fridge. Their trick was grating it on a box grater to get it pliable fast.
