To balance the pungency of raw garlic or onion in a dish, add an acid like lemon juice or vinegar, a sweetener like honey or sugar, or a fat like olive oil or avocado. These ingredients help to mellow the sharp flavors.
Raw garlic and onions contain sulfur compounds that create their characteristic pungent flavor. When these compounds are broken down (through chopping or crushing), they become even more intense. To counteract this intensity, consider the following approaches:
Acid: Acids like lemon juice, lime juice, vinegar (balsamic, red wine, or apple cider), or even a splash of tomato juice can neutralize the alkaline sulfur compounds. Start with a small amount and taste as you go.
Sweetness: A touch of sweetness, such as honey, maple syrup, agave, or even a pinch of sugar, can balance the sharpness. The sweetness rounds out the flavor profile and makes the raw onion or garlic less aggressive.
Fat: Fats like olive oil, avocado, or even a dollop of sour cream or yogurt can coat the palate and reduce the impact of the pungent compounds. The fat also helps to carry the flavors of the other ingredients, creating a more harmonious blend.
Salt: Salt can help to draw out moisture and mellow the flavor of raw onions and garlic. Consider adding a pinch of salt to chopped onions or garlic and letting them sit for a few minutes before adding them to your dish.
Other Flavors: Incorporating other strong flavors, such as herbs (parsley, cilantro), spices (cumin, chili powder), or other vegetables, can help to mask the pungency. This works best when the other flavors complement the dish.
If you're making a salad dressing or sauce, let it sit for at least 30 minutes before serving. This allows the flavors to meld and the pungency of the raw garlic or onion to mellow out over time.
