Ingredients

  • 5 beefsteak tomatoes, (1 kg)

  • 1 cup finely chopped sweet onion

  • 3/4 cup granulated sugar

  • 1/4 cup water

  • 2 garlic cloves, minced

  • 3/4 tsp hot-red-chili-flakes

  • 1/2 tsp dry mustard

  • 1/2 tsp coriander

  • 1/2 tsp kosher salt

Instructions

  • BRING a large saucepan of water to a boil. Cut a shallow X in bottom of each tomato, then submerge and cook until skin loosens, 1 min. Remove with a slotted spoon and submerge into an ice bath for 30 sec. Drain, then peel off skin. Chop to make 5 cups.

  • STIR onion, sugar, water, garlic, pepper flakes, mustard, coriander and salt in same saucepan. Cook over medium, stirring often, until sugar is dissolved, 2 to 3 min.
