Chatelaine Triple Tested

Did you know one tablespoon of ketchup con­tains about a teaspoon of sugar? Here’s our fix.

Ingredients

  • 2 tsp canola oil

  • 3 yellow onions, thinly sliced

  • 1/4 cup water

  • 2 roasted red peppers, rinsed, chopped and patted dry

  • 156-mL can tomato paste

  • 1 1/2 tsp cider vinegar

  • 1 tsp Dijon mustard

  • 1/8 tsp salt

  • fresh pepper

Instructions

  • HEAT canola oil in a medium saucepan over medium. Add onions and cook, stirring often with a wooden spoon, until very soft and browned, 20 min. Add water, scraping brown bits from the bottom of the pan, and stir until no liquid remains, 1 to 2 min. Stir in roasted red peppers and tomato paste until warmed through, 2 to 3 min. Remove from heat, then add cider vinegar,  Dijon mustard and salt. Season with fresh pepper.

  • SCRAPE into a blender and whirl until smooth. Let cool to room temperature and refrigerate in an airtight container up to a week.
