Nobody would describe my mother as a good cook. But she made a Passover brisket from a recipe much like this one -- I think hers was from the Settlement Cookbook, which I inherited. And it always came out good. It's the dried fruit that made it good.
(This recipe cooks it on a smoker for obvious reasons, but you easily can do it in a slow cooker or, as mom did, in a low oven.)

@estherschindler Bought a copy for $1 not knowing what it was. I know it came from Chicago because there is a Commonwealth Edison advert for a lightbulb exchange if one calls RANdolph 1200. Mine is from 1931 and whoever owned it attached all sorts of bits: The correct use of the flag, Telephone ABCs, a house floorplan, recipe clippings from the newspaper and magazines.
The other jewel is Meta Givens green cookbook.
