Rinse the tomatoes. Cut them in half and remove the seeds using a teaspoon. Place the tomatoes (skin up), garlic and coarsely chopped onion on a baking sheet lined with baking paper.
Preheat the broiler in your oven. Broil the tomatoes (insert the pan directly under the broiler) until the skins begin to blacken (about 5 – 7 minutes).
Transfer the vegetables into a blender, add salt and fresh chili peper to taste, then blend into a smooth puree. Transfer in a heatproof bowl and let cool down at room temperature.
Add the lime juice, taste and season with more salt or lime juice if necessary. Store in refrigerator for up to 4 days.
