Me too. I massively over cater on food and drinks, I can’t fathom inviting people to my home for a meal and then working out how little I could get away with giving them. Three small glasses of wine each over the course of an evening, is really tight, even if you don’t drink, it’s no different to saying you can have three small soft drinks over the course of rhe evening.
i was brought up though where hosting was an act of love. So for us it’s big serving dishes, help yourself, extras available. If going quite formal I’d serve fish or the meat plated initially, but only the meat or fish, and the sides on the table in big serving dishes and extra portions of the fish or meat available on the table too, large glasses for rhe wine, bottles on the table again.
i do have a friend who under caters the food, she cooks just enough for a small recommended portion each, but she puts in small serving bowls so everyone takes a little portion and makes sure there is enough left. She chucks the booze down your neck though, I think she just can’t work it out as she’s the most generous person I know. It’s like she can’t get her head round how much 10 folks will eat.😂
however some will do it deliberately. Like here’s a small bit of fish , three little potatoes and some vegetables. Nah, go big or go home.
