This is what I provide in terms of food/drink:
salt shaker
pepper shaker and a pepper corn grinder
olive oil in a small 8-ounce bottle that I can replace periodically
mustard, ketchup, and mayonnaise in 16-ounce squeeze-bottles
spice rack with 24 spices
sugar in a pourer jar and also sugar cubes in a bowl
ground coffee in a large bin
Individual liquid coffee creamers (Mini Moos) and a jar of powdered coffee creamer
A few individual serving packages of powdered hot cocoa
A variety of individually-packaged tea bags.
A few 0.5L bottles of water (usually 2x number of guests, but sometimes more).
Still looking into providing butter in individual packets. The only items I’ve found so far were cases of several hundred which is not practical for me.
Another host recently mentioned he provided individual instant oatmeal packets and I’m going to try that out with the next guests.
