Choosing: Select sweet onions that are firm and heavy. Check for any signs of mold and mildew.

Look for those that are light golden-brown in color, with a shiny tissue-thin skin and firm, tight, dry necks. Ordinary storage onions are darker and have a thicker skin.

When cut into, they should have a creamy white interior.

Avoid onions with soft spots or surface bruises.

Buying: In markets, to tell whether an onion is sweet, it should have thinner, lighter color skin than storage onions and it tends to be more fragile.

Sweet onions tend to be a bit more expensive.

Preparation and Use

Sweet onions can be eaten raw or sliced/chopped and added to salads or sandwiches. They are also perfect grilled or fried.

Cleaning: Peel the onion and cut in half, vertically, through the stem end.

To chop, lay each onion half flat, slice vertically and slice horizontally. To make it easier to do the horizontal cuts, leave 1/8" uncut at one end when you do the vertical slices.

Conserving and Storing

Sweet onions do not store well, it is best to use them within the week before they soften and start to rot.

Sweet onions are high in water and sugar content so they require more care when storing. Treat them gently to avoid brushing. Store away from potatoes because they will absorb water.

Sweet onions will keep for 4-6 weeks or longer. Cut onions should be wrapped tightly in plastic wrap and refrigerated.
