USDA Grading

• Prime – highest and most expensive.

• Choice – most common grade sold in markets.

• Select – least expensive, sometimes sold as a store brand.

Tenderness

• Mechanical Methods – grinding, pounding, and cutting, tenderize meat by breaking down elastin.

• Acids – chemically softening the collagen and breaking down elastin. Tomatoes, sour cream, yogurt, vinegar, lemon juice.

• Commercial meat tenderizer – spice that may be added to help.

• It is important to properly cook meat in order to kill harmful bacteria.

– Put thermometer in meat about 2 inches inside. Do not rest on bone or fat. The temperature should be at least 160 degrees.
