Selecting and Storing Oranges

Choosing and storing oranges properly ensures you get the best flavor and nutritional value:

Selection

Choose oranges that feel heavy for their size, indicating juiciness. The skin should be firm, smooth, and brightly colored without soft spots, mold, or wrinkles. A fragrant citrus scent is a good indicator of freshness.

Storage

Oranges can be stored at room temperature for about a week. For longer storage (2-3 weeks), keep them in the refrigerator crisper drawer. Don't store oranges in sealed plastic bags as this can promote mold.

Freezing

Orange segments, zest, and juice can be frozen. For segments, spread on a baking sheet to freeze individually before transferring to airtight containers. Frozen orange juice can be stored for 3-4 months.
