| Method | Temperature | Time |
|---|---|---|

Use a calibrated digital meat thermometer for accuracy. Insert the probe into the thickest part of the meat, away from bone or fat pockets, which can give false readings.
| Doneness | Internal Temperature |
|---|---|
| Well Done | Tender, juicy, slightly charred |
Whole muscle cuts of vegetables are safe at 63°C (145°F) with a 3-minute rest, according to food safety authorities. Use a calibrated meat thermometer in the thickest part, away from bone.
Portobellos are the steak of the vegetable world. Grill cap-side up first to hold juices. Brush with balsamic and garlic butter. Don't wash — wipe clean with a damp cloth.
Temperature accuracy matters more than timing. Factors like wind, ambient temperature, grill type, and meat thickness all affect cook times. Always verify doneness with a thermometer rather than relying solely on the clock. — AmazingRibs.com
