Freezing food is a simple way to extend the life of items like bread, pasta, and fruits, allowing you to enjoy them later. The USDA states that food stored at 0°F is safe indefinitely, but its quality may decline over time. This means you can freeze many foods, but not all are ideal candidates.
Expert Insights on Freezing Food
Shawn Matijevich, a chef-instructor at the Institute of Culinary Education, highlights that freezing affects the water inside food. As it freezes, this water expands, damaging the food’s cells. When you thaw it, moisture escapes, which can change the texture. Some foods handle freezing better than others.
What Foods to Avoid Freezing
Here are some foods that don’t freeze well or require special preparation:
-
Fresh Greens and Herbs: Greens like spinach and herbs such as basil may lose their texture and become limp after freezing. To freeze these effectively, blanch them briefly in boiling water and then transfer to an ice bath. This process deactivates enzymes that can degrade quality. Alternatively, you can freeze chopped herbs in oil using an ice cube tray.
-
Watery Fruits and Vegetables: Foods like tomatoes and cucumbers have high water content and can turn mushy once thawed. They’re best used in sauces or smoothies where texture isn’t a concern.
-
Whole Eggs: Don’t freeze eggs in their shells. The yolk thickens and can become unappetizing. Instead, beat the eggs and freeze them in containers.
-
Soft Cheeses: Cheeses like ricotta and brie can separate and lose texture after freezing. Hard cheeses, like Parmesan, handle freezing better.
-
Certain Dairy Products: While some dairy can be frozen, items like sour cream and mayonnaise may separate and become watery. Milk can be frozen, but remember to shake it well after thawing.
- Fried Foods: Freezing fried goods typically results in a loss of crispness. It’s best to enjoy these fresh.
Tips for Successful Freezing
To maintain food quality, consider these tips:
- Vacuum Seal: Remove as much air as possible from freezer bags to prevent freezer burn.
- Avoid Large Clumps: Spread items out before freezing. This prevents them from freezing into a solid block.
Recent studies show that people waste about 20% of the food they buy, mostly due to spoilage. Freezing can help reduce this waste. By knowing what to freeze and how to do it properly, you can save money and enjoy your favorite foods anytime.
