These onions are a great garnish for salads, grain bowls and tacos. You can add carrots or not. Or other veggies you like, such as cucumber or cauliflower, for example. 1/4 cup white vinegar 1/2 cup water 1/2 Tbsp Kosher salt 1 Tbsp maple syrup 1/2 medium red onion, thinly sliced 2-3 Tbsp matchstick carrots (optional) Bring the water and vinegar almost to a boil. add the salt and maple syrup and whisk until all is dissolved. Place onions in a small bowl with the carrots. Pour over the hot pickling liquid. Toss to mix well. Refrigerate for at least half an hour (I use the freezer to speed things up - but don't forget them!). Drain and use liberally.
