Ingredients
1largered onionsliced thin
1largewhite onionsliced thin
3tablespoonsdistilled white vinegar
2 1/2tablespoonssour orange juiceor mix of orange and lime juice
Slice the Onions: Thinly slice the red and white onions. Add them to a bowl.
Marinate: Pour in the vinegar and sour orange juice. Add salt and sugar. Give it a good mix and let it sit for 10–15 minutes.
Heat the Oil: Warm the oil in a skillet over medium heat.
Sauté the Onions: Add the onions to the skillet, along with just a bit of the liquid they released while marinating (enough to boost the flavor, but not too much). Cook for about 5 minutes, just until they soften slightly but still have a bit of bite.
Remove from heat once the onions are tender with a slight bite.
Notes
1. Onion Variety TipYou can use either all red or all white onions, depending on what you have on hand. Red onions give a sweeter, bolder flavor, while white onions are milder.2. Adjusting for More Tang or SweetnessIf you prefer your onions on the sour side, add a bit more vinegar or citrus. If you want a milder, sweeter taste, simply add more sugar or reduce the amount of vinegar. The balance is totally up to you.3. Don't have sour orange?Mix equal parts orange juice and lime juice for a similar citrusy flavor.Storage:Store in an airtight container in the fridge for up to 3 days. Reheat in a skillet for 1 to 2 minutes to bring back the texture.
