Sourcing and Storage Tips
Selecting quality onions and storing them properly ensures maximum freshness and flavor. These practices also support sustainable food systems and minimize waste.
Buying Guide for Onions
Look for firm, dry onions with shiny, crisp outer skins. Avoid those with soft spots, bruises, or signs of sprouting. Choose onions heavy for their size, as this indicates good moisture content.
Opt for locally grown onions when possible to support regional farmers and reduce transportation emissions. Consider purchasing organic varieties to limit pesticide exposure.
At farmers markets, ask growers about their cultivation practices. Many small-scale producers use sustainable methods even if not certified organic.
Storing Onions for Freshness
Store whole onions in a cool, dry, well-ventilated place away from direct sunlight. A mesh bag, basket, or open container works well. Avoid plastic bags, which trap moisture and accelerate spoilage.
Properly stored, most onion varieties can last weeks or even months. Check periodically and remove any that show signs of decay.
For cut onions, wrap tightly in plastic and refrigerate for up to a week. Freeze chopped onions in airtight containers for longer storage.
To extend shelf life, separate onions from potatoes and other produce that release ethylene gas.
