Hi. I'm having a problem with a cookie I've made for years. It is a variation of a Florentine and similiar to the lacy cookies that are formed around a handle into a tube. The ingredients-butter, sugar, heavy cream, ground almonds and a small amt. of flour are cooked on the stove, and the batter dropped on the cookie sheet. They are very crsip and somewhat fragile, but this year the cookies are crumbling, and I can't figure out why. They are supposed to be coated w/ chocolate, but there's no way these can be done without crumbling. Can anyone help me figure out what's going on?
