Today I bought new cookie cutters and immediately decided to try, I couldn't resist. The dough is quite simple: mix the sour cream, soft (but not melted) margarine, flour and starch. It turns out soft, pliable dough. Roll out quite thinly, cut out biscuits (here the course went to the new molds). Cut midway I also had baked turned out mini cookies.

Bake in a preheated 200* oven for 10-15 minutes, longer is not necessary. Cookies are only slightly yellow and swells.

Let cool slightly (so you can hold), the upper half fill the icing sugar, the lower lubricated with jam and put them together.

Biscuits are very savoury, so its taste depends on the filling. With jam is a sweet cookie. And you can make a savoury filling such as pate or cream cheese, and get snack cookies. Someone like that...
