Keep the rim of the plate clear of sauces, spills, anything; it frames the food.
Pass all dishes from the left. Guests and servers should pass dishes from left. The logic behind this is that most people are right-handed and this allows them them to serve themselves from the dish while it is being held by the passer. Nowadays it is less likely that the passer will continue to hold the dish, but will expect you to take it, so if you are left-handed, it won’t be a problem. Place the dish down on your side plate to serve from it. [2] X Research source As the cook, or host, always serve yourself last. This is polite and also sensible, since you’ll probably be busy anyway with host’s duties.
