Yes, soaking sliced raw onions in cold or ice water for 10-30 minutes helps significantly by reducing their harsh, pungent flavor and making them milder, sweeter, and crisper, which is great for salads and sandwiches without losing crunch. This works by diffusing the sulfur compounds responsible for the strong bite and eye-watering effect.
The sulfur compounds that give the raw onions their pungent, harsh flavor dissipate in the bowl of water, leaving the resulting onion with a more mellow flavor.
When preparing raw onions, soak in cold water before hand to remove some of the pungency and soften the flavor. However since soaking too long will dilute the flavor, soaking in cold water for 5 to 10 minutes is recommended.
When you slice onions, they release sulfur compounds that cause their strong taste and tear-inducing effects. Soaking them in cold water for about 10 minutes dilutes these compounds, resulting in a sweeter, crisper onion.
This natural property of onions makes them especially helpful when you're feeling sick, as they help to open up the nasal passages and relieve sinus congestion. Dr. O'Neill shares a simple tip for using onions to help with colds: if you or a child have a cold, you can slice up an onion and place it in the bedroom.
To get rid of a cough fast, use home remedies like honey (for those over 1 year old), warm fluids (tea, broth), and steam from a humidifier or shower to soothe your throat and thin mucus; gargle with salt water; suck on lozenges; and avoid irritants like smoke, while over-the-counter (OTC) meds might help, prioritizing hydration and rest is key for relief.
You can get rid of the strong taste by soaking sliced onions in ice water for 20 to 30 minutes or by sprinkling them with an acid such as vinegar. Onions soaked in ice water will get very crisp while those sprinkled with vinegar will soften a bit, but they will lose the strong taste and become sweeter.
This one simple step tames the bite of the raw onions and mellows out their flavor. The sulfur compounds responsible for that harsh "biting" flavor and onion's powerful aftertaste dissipate into the water from the cut surfaces of the onion.
Method 1- give your sliced onions a soak in ice water for about 10-15 minutes! This crisps those slices up even more and leeches out a bit of that raw taste—great for finishing sandwiches, ceviches, etc.
A: Chopped or sliced onions can be stored in a sealed container in your refrigerator at the proper temperature of 40°F or below for 7 to 10 days (Source: USDA).
So while onion water certainly won't hurt your health, there isn't “any research that supports the effectiveness of onion water in speeding recovery from RSV, sinus infections, or colds,” Tamburello says.
They advise their audience to make onion water by slicing raw onions, placing them in a jar of filtered water, and letting them soak overnight in the fridge. Drinking the infused water is said to clear congestion and kick the immune system into high gear.
Garlic and onions
These vegetables are part of a group called alliums (which also includes scallions, shallots, chives, and leeks), and they're known for their anti-inflammatory properties. “They can all have a beneficial effect on reducing the amount of excess mucus that builds up,” Dr. Kansal says.
What Experts Say. Food safety guidelines when it comes to rinsing onions is that washing all produce is recommended before using. Dirt, bacteria, and pesticide residue can cling to the outer layers of onion, which can then transfer to your knife or cutting board.
The water rinses the enzymes off, and the cold temperature makes them less reactive. This is why some suggest freezing an onion for a few minutes before slicing it to cut back on tears.
Gargling with warm salt water can help soothe a sore or scratchy throat, which often accompanies a cough. Salt water helps to reduce inflammation and kill bacteria, providing temporary relief. Dissolve half a teaspoon of salt in 1 cup of warm water, gargle the solution for a few seconds, and spit it out.
To help clear mucus, focus on warm, hydrating fluids like water, herbal teas (ginger, peppermint, thyme), and broths, which thin congestion, while avoiding dehydrating drinks like coffee and alcohol; lemon with honey in warm water is also excellent for soothing and loosening mucus. Hydration is key, as it makes mucus easier to cough up, and certain teas offer anti-inflammatory or decongestant properties, like menthol in peppermint or antioxidants in green tea, to further help.
