Baking staples: flour, white and brown sugar, vanilla, baking soda and baking powder, salt (optional), eggs, milk, vegetable oil or canned Crisco.

Household staples: toilet paper, paper towels, laundry and dish detergent.

I don't consider any of these as "emergency" staples - just things that I think most everyone has around the house all the time.

Buttermilk??????? - definitely not a staple in this household. I could count on one hand and have fingers left over, if counting the number of times I have ever used buttermilk for anything.
