Earthquake zone + icy winter hill + power outages trained me to have extra food and paper products around, and COVID reinforced it. Not a big deal. We always have extra soup, rice, pasta, cereal, oil, tuna, dried mushrooms, canned vegetables, nuts, dried fruit, crackers, frozen meat, frozen veg, and toilet paper. Not in huge quantities, but even if we lost the freezer, we could manage for a few weeks.
