Per egg white:
- 1/4 c sugar
- 1/2 tsp vanilla extract
- 1/2 c chocolate chips
- pinch salt
Preheat oven to 400 F.
Beat eggs to soft peaks.
Add sugar, vanilla, and salt. Beat to stiff peaks.
Fold in chocolate chips.
Put lumps on a silpat-or-parchment-covered baking sheet.
Put baking sheet in oven and TURN THE OVEN OFF.
Leave in the oven overnight. DO NOT OPEN THE OVEN DOOR. You want the lingering heat to bake the cookies. Don’t check on them until morning.
If something went weird and the cookies feel too sticky in the morning, just turn your oven on to its lowest setting for a bit until they dry out enough. This doesn’t come up often, but it occasionally has for me in older apartments with some ovens in some weather or who knows.
