I'm married (nearly 17 years now) and both my husband and I are pretty busy, so doing anything substantial is always a trick. We both work, and both take turns making dinner, or whatever on the weekend.
My favorite family cooking traditions
My grandma's homemade chicken noodle soup, turkey meat/sage stuffing, piggies in a blanket (cabbage rolls cooked in sauerkraut).
My cooking triumphs
Cakes, mostly Kahlua Chocolate cake, which is always a hit.
My cooking tragedies
Various dinner ideas. I seem to be better at baking.
