Ingredients

2 1/2 cups apple-cider vinegar 

1/3 cup sugar 

2 teaspoons coarse salt 

4 medium carrots, peeled and cut diagonally 1/4 inch thick 

2 small red onions, peeled, halved, and sliced into 3/4-inch wedges 

4 jalapeno peppers, cut lengthwise into quarters, seeds removed with a small knife 

Preparation

Combine vinegar, sugar, and salt in a medium saucepan with 3 cups cold water; bring to a boil over high heat and stir to dissolve sugar.
