Soak thinly sliced raw hot onion in cold water briefly, then drain it well. A little lemon juice or vinegar can also mellow the bite. Avoid soaking it for too long, which can dilute its flavor and soften its texture.
Cutting raw hot onion releases volatile sulfur compounds that irritate the eyes and trigger tears. Chilling the onion before cutting, using a sharp knife, and working near ventilation can reduce the irritation.
Yes, raw hot onion can trigger heartburn or reflux symptoms in some people. Its pungent compounds may aggravate a sensitive digestive system; if you notice symptoms, try a smaller serving or choose cooked onion instead.
Yes, raw hot onion can cause gas or bloating, particularly in people sensitive to fermentable carbohydrates. Eating a smaller amount or having the onion cooked may make it easier to tolerate.
Put cut raw hot onion in a sealed container in the refrigerator and use it within a few days. Keep whole onions in a cool, dry, well-ventilated place rather than a damp or sealed bag.
Yes, rinse raw hot onion under running water before cutting, especially after removing the outer skin. This helps remove dirt from the surface and reduces the chance of transferring it to the cut onion.
Choose a raw hot onion that feels firm and heavy for its size, with dry, intact skin. Avoid onions with soft or damp spots, visible mold, or an unpleasant smell, as these can signal spoilage.
Yes, raw hot onion can cause temporary bad breath because sulfur compounds linger after eating it. Drinking water and brushing your teeth and tongue can help reduce the odor.
Often, yes: raw hot onion can be more irritating or cause more gas than cooked onion for people with sensitive digestion. Cooking softens its texture and pungency, though individual tolerance varies.
Yes, you can freeze raw hot onion, preferably chopped and packed in an airtight freezer container. It will soften after thawing, so frozen onion works best in cooked dishes rather than salads or other raw preparations.

Raw hot onion is simply onion served uncooked; “hot” here means sharp and pungent, not seasoned with chilli. In Turkey, it commonly comes alongside kebabs, köfte, dürüm and other grilled dishes, and can also be sliced into salads or piyaz. It is an ingredient and side rather than a cooked dish.
The pieces are crisp and juicy, with a lingering bite that varies by onion. It provides fibre and vitamin C while remaining low in energy. For a milder flavour, soak sliced onion briefly in cold water, then drain it; parsley, sumac and lemon make natural companions.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
