  • 2 pounds Roma tomatoes
  • 2 medium vidalia onions
  • 1 tablespoon butter
  • 1/2 cup dark brown sugar packed
  • 2 tablespoons apple cider vinegar
  • 4 cloves garlic finely minced
  • 1 tablespoon ginger fresh, finely grated
  • 4 dried Fresno chiles crushed, more or less to taste
  • 1 teaspoon sea salt
  • 1/4 teaspoon cayenne pepper
  • 1/4 teaspoon cinnamon
  • 1/4 teaspoon cumin
  • 1/8 teaspoon ground allspice

Cook That

  1. Preheat oven to 450 degrees. 

  2. With a paring knife, cut the core out of the tomatoes. Cut each tomato in half lengthwise and place them cut side down onto a rimmed, shallow baking pan.

  3. Bake for 45 minutes. Let the tomatoes cool. Gently remove the skins, they will peel right off. Roughly chop the roasted tomatoes into 1/2 inch pieces.

  4. While the tomatoes are roasting, melt the butter in a medium sized stainless steel saucepan. Peel and slice the onions into thin rings. 

  5. Add the onions to the butter and stir. Cook on low, stirring occasionally, for about 30 minutes until the onions are soft and golden brown.

  6. Stir the tomatoes, brown sugar, vinegar and all spices into the onions. Heat the tomato jam mixture to a boil, stirring constantly.

  7. Reduce heat and simmer on low for 1 hour or more, stirring frequently to prevent sticking. Cook until the mixture is rich, thick and resembles the consistency of jam.

  8. Remove from heat and store in a sealed jar. If not using immediately, refrigerate.
