Frequently Asked Questions About Rib

How many ribs per person?

Plan for 4-6 ribs per person as a main course. A full rack of baby back ribs has 10-13 ribs and feeds 2 people. Spare ribs are larger, so 3-4 per person works.

What's the difference between baby back and spare ribs?

Baby back ribs are smaller, leaner, and more tender with a curved shape. Spare ribs are larger, fattier, meatier, and more flavorful. Baby backs cook faster; spare ribs are more economical.

How do I keep ribs warm for a party?

Wrap cooked ribs tightly in foil and hold in a 200°F oven for up to 2 hours. Add a splash of apple juice inside the foil to keep them moist.
