What are some of the food related things that your mom did that drove you nuts?
My mom for example would always:
store the peanut butter in the fridge.
Being an Italian immigrant, she put parsley and garlic in every amercian dish we begged her to make - hamburgers, Meatloaf (I love the american kind), fried chicken (which was never really fried but breaded and baked.
She always screwing up the turkey and mash potatoes. Since she makes these dishes are not Italian, they don't warrant the care and attention that go into everything else she makes.
Refuse to buy bottle stoppers. Instead she used to put pieces of aluminum foil over the mouth of soda bottles. The soda went flat in ten minutes.
As a kid, I would have to beg her for a swanson TV dinner (fried chicken, mixed veggies, mash potatoes and apple cobbler with the requisite three pieces of carrot in it). When I finally got one she would take it out of the aluminum dish and put it on a plate, completely ruining the TV dinner experience.
