Ingredients

1 1/4 pounds vine tomatoes 

2 jalapeno chiles, stems removed 

1/2 medium white onion, cut into wedges 

3 garlic cloves, unpeeled 

1/4 cup water 

1 tablespoon plus 1 teaspoon white vinegar 

1 teaspoon coarse salt 

Preparation

Preheat broiler. Place tomatoes, jalapenos, onion, and garlic on a rimmed baking sheet. Broil, turning vegetables often and rotating baking sheet frequently, until tomatoes are blistered with dark spots and flesh is tender, about 5 minutes. Let cool. When vegetables are cool enough to handle, peel garlic. Puree garlic, tomatoes, jalapenos, onion, water, vinegar, and salt in a blender until almost smooth. Serve warm or chilled. Sauce can be refrigerated for up to 3 days.
