Food, hand
My wife @Anri is a genius. I tried freezing guacamole but had trouble with breaking the flat slabs after they were frozen to get portion sizes out, and also they would get sharp edges and cut their baggie.
But I really wanted to freeze guacamole, because avocados get so dang cheap here when they're in season, but I can't eat them all.
She suggested ice cube trays.
My life is forever changed.
