- 2 tablespoons extra-virgin olive oil
- 1/2 cup onion, minced
- 1/2 cup tomato paste
- 1 1/2 cups raisin paste or whole raisins
- 4 1/4 cups cold water
- 1 tablespoon garlic, minced
- 1 1/4 cups balsamic vinegar
- 5 tablespoons applesauce
- 5 tablespoons roasted garlic paste
- 1 1/2 teaspoons mustard powder (dried mustard)
- 1/4 cup corn syrup
- 3 tablespoons Worcestershire sauce
- 3 tablespoons salt
- 1 teaspoon freshly ground pepper
Place extra-virgin olive oil in large sauce pot over medium high heat, add onions and reduce heat to medium. Saute onions until golden brown then add tomato paste, cook for 1 minute. Turn heat back to high, add remaining ingredients with exception of salt and pepper. Bring to a boil, reduce heat to medium and simmer ingredients for 10 to 15 minutes.
Remove pot from heat, place into blender* and puree until smooth. Add salt and pepper.
If the mixture is not smooth enough add a few teaspoons of water and puree until smooth.
* When blending hot liquids: Remove liquid from the heat and allow to cool for at least 5 minutes. Transfer liquid to a blender or food processor and fill it no more than halfway. If using a blender, release one corner of the lid. This prevents the vacuum effect that creates heat explosions. Place a towel over the top of the machine, pulse a few times then process on high speed until smooth.
