Preparing Cocoa Snails involves making a laminate dough, which is similar to the kind of dough made for croissants. If you've done this before, the first part of the instruction will be familiar. If you haven't, it's not that difficult, but one naturally improves with practice. (This vidoe shows the process of making a laminate dough, with cocoa snails in mind. Don't worry if you can't understand her, I couldn't either).

This process generally goes a few hours because of the rest periods involved. You don't want to start this much after 7 pm. Expect to be baking these around 10-11 pm.

A note if you find yourself making this in a warm kitchen: because there's butter involved, definitely chill your rolling pin, and you can cool your worksurface by placing a baking pan with ice on it while your dough is resting. This isn't typically necessary, but having done this in warm environments I know that this can help, particularly if you are new to making laminate dough. As one gets better the whole process goes more quickly and precautions like this aren't needed.
