I missed being able to say this on the last thread, so apols for the off topic.
No idea how to spoiler. Also sorry.
Pretend this is under a spoiler, ok?
Jack (presumably) isn't Jewish, but she IS part Greek-Cypriot.
My personal old Harold is of the G-C variety, and we often make a very classic Greek-Cypriot soup, Avgolemono, that's the G-C version of the 'make you better' Chicken Soup that many cultures seem to have developed.
Why didn't Jack make that, rather than butcher a Jewish recipe?
(It's just chicken (with bones, skin and fat- so either a whole chicken or wings/ drumsticks) boiled, strained, remove the meat and put aside, cook white rice in the chicken stock water, let cool slightly, add whisked (whole) egg/s and some lemon juice and salt to taste, serve.
It's delicious, cheap, easy and great for when you're ill. (This is the family version of the recipe, which varies from region to region/ family to family.))
Seems easier, cheaper and less culturally-appropriative, but hey, this isn't a rational person we're talking about here, I suppose.
