A lot of popular canned ingredients from the era taste as though they’ve been embalmed. If canned asparagus, canned peas, canned spinach, canned corn, or canned carrots are your only options, resuscitate them. Drain any well, put it in a pot, add a quarter as much butter as vegetable, let it simmer for fifteen minutes, then pulse it in a food processor and eat it on toast or crackers.
