Jam:6 large ripe tomatoes, cored and cut in half crosswise (about 4 pounds)
⅓ cup sugar
⅓ cup grated onion
3 cloves, garlic minced
2 jalapeño peppers, minced
¼ cup chopped fresh cilantro
3 tablespoons fresh lime juice
¼ teaspoon salt
Steak:
1 tablespoon grated lime rind
⅓ cup fresh lime juice
2 teaspoons olive oil
2 jalapeño peppers, minced
2 cloves, garlic minced
2 lbs. flank steak, trimmed
½ teaspoon salt
Cooking spray
To prepare jam, grate tomatoes, flesh side down, over a large bowl to form 5 1/2 cups pulp; discard skins. Combine pulp, sugar, onion, 3 garlic cloves, and 2 jalapeños in a medium saucepan; bring to a boil. Reduce heat, and simmer until reduced to 2 1/4 cups (about 20 minutes), stirring occasionally. Cool to room temperature. Stir in cilantro, 3 tablespoons juice, and 1/4 teaspoon salt.
To prepare steak, combine rind, 1/3 cup juice, oil, 2 jalapeños, and 2 garlic cloves in a large zip-top plastic bag. Add steak; seal. Marinate in refrigerator 8 hours or overnight, turning bag occasionally.
Prepare grill.
Remove steak from bag; discard marinade. Sprinkle both sides of steak evenly with 1/2 teaspoon salt. Place steak on a grill rack coated with cooking spray; grill 3 minutes on each side or until desired degree of doneness. Let stand 5 minutes. Cut steak diagonally across the grain into thin slices. Serve with jam.
