From the 1946 edition of Joy of Cooking, and not to be found in subsequent editions (at least not the newer ones--I have three different editions now and am passing on the newest one). These are delicious and an unusual side dish (1-2 each) or vegetarian main dish (serving 2-4 per person). Since this is from a fairly old cookbook, actual measurements are nonexistent for many of the ingredients. I HAVE made these and remember loving them, but that was 30 or so years ago. I shall make them again soon and edit the recipe to add suggested amounts and estimated times. The onion cases may be made ahead; the active prep time of 30 minutes assumes they are premade. The time of 90 minutes includes making the onion cases.
