Running out of ideas for suitably penitential lenten recipes? The Diocese of Arkansas has come up with a quantity of suggestions, which you can sample here.
Having looked at the recipes with more attention today, I can confirm that most of them are truly penitential: I wasn't aware that Americans are still quite so attached to canned food. All but a few recipes seem to involve combining one can with another. There is a recipe for chowder, which involves combining a can of potato soup with a can of salmon. Now that's penitential!
It reminds me of my aunt's (God rest her soul) story of an American visitor to her home; this would be in the 1960s, I should think. She went down the garden to pull some carrots, and her visitor accompanied her. Up came a fine carrot, which she placed in her trug. She heard an intake of breath at her side, followed by an appalled 'you're gonna eat that?'.
