Hot ready pizza (slice)

Savory and cheesy with a chewy crust, best right after it's cut.

Lens analyzed

This is a single slice of pizza sold hot and ready to eat, either from a grocery store's hot case or a pizzeria counter, meant to be eaten within the hour rather than saved. It's priced and sold by the slice rather than the whole pie. Toppings and crust style vary by where it's bought.

Where it comes from

Selling pizza by the slice began in New York City pizzerias in the early 1900s, giving customers a quick, affordable meal without having to buy a whole pie. Grocery stores later added their own hot cases offering the same by-the-slice format for shoppers looking for something to eat right away.

Buying it

Buy it as close to serving time as you can, since a slice held under a heat lamp loses its crispness the longer it sits.

Storing it

Eat it the same day if possible. If you have leftovers, refrigerate the slice right away in a covered container and reheat it rather than eating it cold from the fridge the next day.

Keeps about 1 day in the fridge.
