How to Choose and Store Sardines: Tips for Freshness and Quality

When selecting sardines, it’s essential to prioritize both freshness and quality to ensure you’re getting the best taste from this nutritious fish. Start by examining the appearance of the sardines. Look for fish that have shiny, metallic skin, clear eyes, and a firm texture. Avoid sardines that appear dull or have a slimy coating, as these can indicate spoilage.

Use them quickly: Aim to consume fresh sardines within 1-2 days of purchase for the best flavor and texture.

Freezing option: If you can’t use them right away, freezing sardines can extend their shelf life. Wrap them tightly in freezer-safe packaging and store them; they can last up to three months.

Storage Method	Duration	Notes
Refrigerator	1-2 days	Best for fresh sardines.
Freezer	Up to 3 months	Ideal for longer storage.
In Oil (Canned)	Years (unopened)	Check expiration date.
