How to buy red onions
With their deep purple skin and pale flesh, red onions are great for adding colour and flavour to savoury dishes. Look for red onions that are firm and dry, with shiny, tight skin. If they have soft, damp spots, they are not fresh.
How to store red onions
Whole red onions will keep for three or four weeks in a dark, cool place – such as in the pantry. A cut red onion should be stored in a container in the fridge and used within a day or two. Cut red onions left at room temperature will dry out and the layers will start to separate.
Cooking tips
- Thinly slice red onions and pickle in white vinegar and a pinch of sugar for 20 minutes, or until tender. Then simply add to salads for a tasty burst of flavour.
- In a frying pan over low heat, caramelise red onions with a little butter or oil and a sprinkle of salt and pepper. Allow to cook slowly for 20 minutes, or until golden. Great for serving with red meat and pizza.
- Roast segments of red onion with balsamic vinegar and rosemary – perfect to serve in a roast vegetable salad with goat’s cheese.
- Stuff red onion rings with breadcrumbs and grated cheese and bake in the oven.
Nutritional facts
