Chocolate tuile recipe
Can you be more specific than "just looking for one that works."
A basic Tuille recipe easily be converted to a chocolate one with the addition of cocoa.
Albeit melted chocolate may give you texture and consistency problems.
Perhaps if you tell us more about the problems you are having, we can help.
Looking at a lot of the online chocolate tuile recipes and I am sure any one of them would work for you as tuile are not that complicated of a biscuit to make and its kinda hard to screw them up.
I will post mine that I call my go classic tuile recipe for you :
1 3/4 oz. (50g) butter
3 1/2 oz. (100g) powdered sugar
2 pcs egg whites
1 1/2 oz. (45g) flour*
Cream the butter and sugar together. Stir in the egg whites until smooth. Add the flour. Allow to rest one hour minimum before using. Line a baking sheet with a silicone mat or non-stick parchment paper. Spread 4 - 6 small spoonfuls of mixture onto the mat or paper, leaving at least 3" in between. Place in the oven to bake for about 6 minutes or until they spread out and the edges begin to brown. Remove from oven, and working quickly, remove each biscuit with a spatula and place into form (whatever it is you are using i.e.: wooden spoon handle or dowel for cigarette style or over a glass or in a tuile form). If the biscuit becomes too stiff, return to the oven to soften.
*If you would like chocolate ones then reduce flour 1 1/4oz. (35g) and add 1 heaping tablespoon Dutch-processed cocoa powder to your flour and mix together.
**Feel free to add flavours to this recipe.
Hope this helps you!
