• Ready to bring out your inner chef? Follow these simple steps:

Step 1: Prepare the Onions

• Begin by peeling the red onion. The vibrant color adds visual appeal to your dishes. Slice it thinly; about a quarter-inch thick works best.
• As you slice, think about how these will brighten up your food. A sharp knife makes this job smoother. If you have a mandoline slicer, now’s the time to use it!

Step 2: Combine the Brine Ingredients

• Grab a mixing bowl. Squeeze the juice of four limes into the bowl. Follow this with one tablespoon of apple cider vinegar. The acidity in these liquids will balance out the sweetness of the onion.
• Next, add ½ teaspoon of agave nectar. This small addition contributes a touch of sweetness. Now, sprinkle in 1 teaspoon of coarse kosher salt, ½ teaspoon of freshly cracked black pepper, and a tiny pinch of red pepper flakes.

Step 3: Mix Well

• Stir the mixture until all ingredients incorporate well. The acidity will begin to soften the onions just by being in contact with the brine.

Step 4: Add Onions to the Brine

• Now, add your sliced onions to the bowl. Make sure each ring is submerged in the brine. Stir them gently to coat thoroughly. This is your chance to embrace the crunch and color — feel the excitement!

Step 5: Marinate

• Transfer your onion mixture to a clean, airtight jar. Seal it well and set aside. Let your pickled onions marinate for at least an hour.
• If you’re not in a hurry, letting them sit overnight in the fridge allows the flavors to meld even better. Use this time to plan your next taco night or salad!
