Defrosting Tips & Techniques
Preparation For Freezing:
1. Freeze meats, poultry, and fish in packages with only 1 or 2 layers of food. Place 
wax paper between layers.
2. Package in heavy-duty plastic wraps, bags (labeled “For Freezer”), or freezer paper.
3. Remove as much air as possible.
4. Seal securely, date, and label.
To Defrost:
1. Remove wrapper. This helps moisture to evaporate. Juices from food can get hot and 
cook the food. 
2. Set food in microwave safe dish. 
3. Place roasts fat-side down. Place whole poultry breast-side down.
4. Select power and minimum time so that items will be under-defrosted.
5. Drain liquids during defrosting.
6. Turn over (invert) items during defrosting.
7. Shield edges and ends if needed. (See Cooking Techniques).
After Defrosting:
1. Large items may be icy in the center. Defrosting will complete during STANDING TIME.
2. Let stand, covered, following stand time directions on page 14.
3. Rinse foods indicated in the chart.
4. Items which have been layered should be rinsed separately or have a longer stand time.
