In a small skillet over medium heat, warm the olive oil. Add the garlic and cook, stirring frequently, until fragrant, 1 to 2 minutes. Be careful not to let the garlic scorch or the resulting sauce will be bitter.
In a nonreactive bowl, stir together the garlic and its oil along with the tomatoes and their juices, the dried basil, dried oregano, dried thyme, pepper, water, and 1 1/2 tablespoons of the vinegar. Taste and season with salt and additional vinegar as desired.
Canned tomatoes vary in salt content, so season the sauce with just a pinch of salt to start, and then gradually add more to taste. When seasoning with the red wine vinegar, add just enough to make the flavor really sparkle; the sauce shouldn’t taste tangy.
Use the sauce right away or cover and refrigerate it for up to 1 week.
