I've come across a few.
My brother made a roast lamb and had no red currant jelly. Strawberry jam it was.
I've an aunt who put sour cream in the trifle. Not quite as bad as Rachel and the beef, but it did not work well.
I've an ex who was making chickpea patties that called for cumin, turmeric and coriander. In case you were wondering, oregano does not make up for a lack of cumin.
