On a parchment lined cookie sheet roast onion, tomatoes, garlic, and peppers at 250 degrees for about 40 minutes until vegetables are soft and have begun to sweat. I only roasted the peppers for about twenty as I had the rest of the ingredients in the oven already as I prepared the peppers. (i’m not sure that roasting makes much difference but I wanted to roast the garlic)
Peel the garlic cloves and then combine all ingredients except lime juice in a medium sized non-reactive pan.
Simmer over low heat for at least an hour (I went two or three), allow to cool and puree in a food processor or blender. Add lime juice and a bit more vinegar to achieve desired consistency.
Store in clean glass jars and refrigerate.
