These elements work together to reduce cholesterol levels and blood pressure. Additionally, studies suggest that onions' quercetin, an antioxidant, may help in preventing certain types of cancer.
How should white onions be stored to maximize their shelf life?
To keep white onions fresh for as long as possible, store them in a cool, dry place with plenty of air circulation. Avoid keeping them in plastic bags or containers, which can retain moisture and lead to spoilage. Ideally, place them in a mesh bag or a basket in a dark pantry or cupboard. This way, they can last for several weeks.
Are there any quick tips for cutting white onions without crying?
Sure thing! To minimize tears, try chilling the onion in the fridge for about 30 minutes before cutting. This reduces the enzyme reaction that causes the eye-irritating gases. Also, using a sharp knife can help, as it creates fewer gases than a dull one. Lastly, cutting onions near running water or a vent can help draw the gases away from your eyes.
