If you've ever been to a Jewish celebration, be it bris, bar/t mitzvah, or wedding, you've surely had some "Jewish Auntie" cake; sometimes it's in a bundt shape, or maybe a loaf, or maybe you've only ever seen it in its classic "4 mouthful slab" form.
The key to Jewish Auntie cake is its durability.
With the right secret ingredient (banana? shmaltz? guilt?) and some careful wrapping in tin foil, the cake can seemingly last forever (frozen, of course). A cake made for little Becky's bat mitzvah will easily make it to her wedding reception; with some luck, it could even make it to her kids' weddings. "Becky bat mitzvah 1993, lemon loaf" written on a piece of masking tape is a sure-fire way to manage a freezer full of cakes.
Don't get me wrong, I love Jewish Auntie cake, and I still occasionally get served the cakes I remember from 30 years ago... and if I could see the masking tape from off the tin foil, maybe I'd confirm that it is the same cake from 30 years ago!
