Ingredients
  • 1 (28-oz) can whole tomatoes in purée
  • 1 medium onion, (about 1 cup) chopped
  • 2 tablespoons olive oil
  • 2 tablespoon tomato paste
  • ½ cup packed dark brown sugar
  • ⅓ cup cider vinegar
  • ½ teaspoon salt
Instructions
  1. Purée tomatoes (with purée from can) in a blender until smooth.
  2. Cook onion in oil in a 4-quart heavy saucepan over moderate heat, stirring, until softened, about 8 minutes. Add puréed tomatoes, tomato paste, brown sugar, vinegar, and salt and simmer, uncovered, stirring occasionally, until very thick, about 1 hour (stir more frequently toward end of cooking to prevent scorching).
  3. Purée ketchup in 2 batches in blender until smooth (use caution when blending hot liquids). Chill, covered, at least 2 hours (for flavors to develop).
