Frequently Asked Questions

How do I calculate cooking time per pound?

Cooking time depends on the type of meat, desired doneness, and cooking method. General guidelines for roasting at 325F: turkey (15-20 min/lb unstuffed), chicken (20 min/lb), beef roast (20-25 min/lb for medium), pork roast (25-30 min/lb). The calculator uses established guidelines and adjusts for your specific weight.

How does changing the temperature affect cooking time?

Higher temperatures cook faster but may dry out food. A rough guideline: increasing temperature by 25F reduces time by about 15-20%. The calculator uses the relationship between temperature and time for common foods to provide adjusted estimates. Always use a meat thermometer for food safety.

How do I adjust cooking time for different weights?

Cooking time does not scale linearly with weight. Doubling the weight does not double the time because heat penetration depends on thickness, not just mass. A 12-lb turkey takes about 3 hours at 325F; a 24-lb turkey takes about 4.5-5 hours, not 6. The calculator uses appropriate scaling formulas.

Does altitude affect cooking time?

Yes — at higher altitudes, water boils at lower temperatures, and the lower air pressure affects baking chemistry. Above 3,500 feet, increase baking time by 5-8 minutes per 30 minutes, increase oven temperature by 15-25F, reduce sugar slightly, and increase liquid slightly. The calculator includes altitude adjustment.

What internal temperatures indicate doneness?

USDA safe minimum temperatures: poultry (all cuts): 165F/74C. Ground meat: 160F/71C. Beef/pork/lamb steaks and roasts: 145F/63C with 3-minute rest. Fish: 145F/63C. The calculator displays target internal temperatures alongside cooking times as a safety reference.
