Revenge Is a Dish Best Served Cold. For Everything Else, Use These Discounted Warming Trays. 

Salton Warming Tray, 3-Plate | $60 | Amazon

The oven is a hot piece of real estate during dinner party preparation, which inevitably means some of your painstakingly prepared dishes will get left out in the cold as the meal comes together. Or, you could invest in these Salton stainless-steal warming trays, now $68 for one that accommodates four-plates and $60 for one that holds three. They promise to keep your food nice and toasty until the eating gets underway, or use them to keep a plate warm for any stragglers who are late to the party.
