23. You pop meat straight from the fridge into the oven or onto the grill.

Result: Food cooks unevenly: The outside is overdone, the inside rare or raw.

Meats will cook much more evenly if you allow them to stand at room temperature for 15 to 30 minutes (depending on the size of the cut) to take the chill off.

A roast that goes into the oven refrigerator-cold will likely yield a piece of meat that is overcooked on the outside and undercooked at the center. As you slice the roast, you’ll see a bull’s-eye effect: The middle is rare (or even raw) while the outside is well done. This is less of a problem with smaller cuts like chicken breasts―though even those benefit from resting at room temperature for five or 10 minutes before cooking.
