To mellow the sharpness of raw onions in salads or raita, soak them in cold water for 10-15 minutes or add an acidic element like lemon juice or vinegar.
Raw onions contain sulfur compounds that contribute to their pungent flavor and can be overpowering in salads and raitas. Several methods can effectively reduce this sharpness without cooking:
Soaking in Cold Water: Submerge the sliced or diced onions in a bowl of cold water for 10-15 minutes. The water helps to draw out some of the sulfur compounds, making the onion milder. Drain the onions thoroughly before adding them to your salad or raita.
Acidic Marinade: Toss the onions with an acidic ingredient like lemon juice, lime juice, or vinegar (white vinegar, apple cider vinegar, or red wine vinegar work well). The acid helps to break down the sulfur compounds and mellow the onion's flavor. Let them sit for about 10-15 minutes before using.
Salt: Sprinkling the sliced onions with salt and letting them sit for about 10 minutes before rinsing them can also help draw out some of the harshness. Be sure to rinse thoroughly to remove excess salt.
Choosing Milder Onions: Opt for sweeter varieties of onions like Vidalia or red onions, which naturally have a milder flavor profile compared to yellow or white onions.
When using the soaking method, change the water once halfway through the soaking time for even better results. This ensures that the sulfur compounds are effectively removed from the onions.
