My Grandma used to make hotpot every Saturday - and we loved it when we went to visit. Grandad made it occasionally too - but he put carrots in his. I have committed an even worse crime and added kale. Sautee chopped onion in olive oil, add chopped beef, brown, add stock. Simmer for a while, add potatoes, simmer more - season. About 10-15 minutes before serving add kale. Slurp, get instantly transported to kitchen in Stockport circa 1978. Victim loved it too (except for the kale, of course).
