--------  ------------  --------------------------------
   1 1/2  pounds        ripe tomatoes -- cored and quartered
                         -- and roasted
   3      tablespoons   olive oil -- divided
   1      medium        onion -- finely diced
   2      cloves        garlic -- finely diced
     1/4  cup           cider vinegar
   2      tablespoons   sugar
     1/4  teaspoon      cinnamon
     1/4  teaspoon      allspice
                        salt and freshly ground pepper

Preparation:

Preheat the oven to 350F. Toss the tomatoes in 1 tablespoon of the olive oil and place on a baking sheet. Roast in the oven for 10 to 15 minutes or until soft. Transfer the tomatoes to a food processor and process until smooth. Strain the tomatoes, pressing against the solids with a wooden spoon to extract as much pulp and juice as possible. Heat the remaining olive oil in a medium saucepan over medium heat and sauté the onions and garlic until translucent. Add the tomato puree and remaining ingredients and continue cooking, uncovered for 25 to 30 minutes, stirring occasionally until thick.
