Frequently asked questions

Should I trust time or temperature?

Temperature — always. Times are estimates; a $15 probe thermometer is the difference between juicy and dry. Pull poultry at 165°F, beef at 145°F+ rest.

Why rest the meat?

Juices redistribute — cut too soon and they flood the board instead of staying in the meat. 20–30 min for big roasts, tented in foil.

Stuffed vs unstuffed — big difference?

Yes, about 15% longer, and the stuffing must hit 165°F too. Many chefs cook stuffing separately for food safety and crispiness.

Do I need to baste?

Not really — basting doesn't penetrate, it just cools the oven when you open it. A buttered cheesecloth or foil tent does more.
