Cookie edges turning out crispy
Occasionally when baking cookies, the edges of the cookies will turn out thin and crispy, instead of chewy and "rounded out". This almost always happens on my oatmeal raisin cookies in particular.
I'm not sure what causes this. Anyone have any speculation as to why this happens?
Should the mascarpone and eggs both be at room temperature to start? My filling looked curdled so I wrapped a hot towel around the moving bowl until it came together. Unfortunately, my foil leaked and this got ruined (I've never done a water bath before. Perhaps the note to use large heavy-duty foil would be nice within the recipe). I will try again when I can bear the loss of the $30 of mascarpone! Also, the cornstarch slurry kept separating before it was time to use it and I had to remix it several times. Is there a reason it's made in part 2 and not in part 3?
