This versatile recipe combines the smoky flavors of charred tomatoes with the freshness of cilantro. Whether you use it as a salsa for dipping or a vinaigrette for salads, it brings a burst of flavor to any dish. The roasting process intensifies the natural sweetness of the tomatoes and onions, creating a rich and complex taste.
While most of the ingredients in this recipe are common, you might need to pay special attention to the cilantro. Fresh cilantro can be found in the produce section of your supermarket, often near other fresh herbs. Make sure to pick a bunch that looks vibrant and green, avoiding any wilted or yellowing leaves.

Ingredients For Charred Tomato Salsa / Roasted Tomato Vinaigrette
Tomatoes: The base of the recipe, providing a rich, smoky flavor when roasted.
Onion: Adds sweetness and depth to the salsa or vinaigrette.
Garlic: Enhances the overall flavor with its aromatic and pungent qualities.
Olive oil: Helps in roasting the vegetables and adds a smooth texture.
Salt: Essential for seasoning and bringing out the flavors of the ingredients.

Technique Tip for This Recipe
To achieve a deeper, smokier flavor in your charred tomato salsa or roasted tomato vinaigrette, consider using a cast iron skillet instead of a baking sheet. Preheat the skillet in the oven, then add the tomatoes, onions, and garlic directly to the hot surface. This method will enhance the caramelization and give your dish an extra layer of complexity.

tomatoes - Substitute with red bell peppers: Red bell peppers provide a similar sweetness and can be charred to mimic the smoky flavor of roasted tomatoes.
onion - Substitute with shallots: Shallots offer a milder, sweeter flavor that can complement the other ingredients without overpowering them.
garlic - Substitute with garlic powder: Garlic powder can provide a similar depth of flavor, though it lacks the fresh, pungent kick of raw garlic.
olive oil - Substitute with avocado oil: Avocado oil has a high smoke point and a neutral flavor, making it a good alternative for roasting.
salt - Substitute with soy sauce: Soy sauce can add a salty, umami flavor that enhances the overall taste of the dish.
black pepper - Substitute with white pepper: White pepper offers a similar heat but with a slightly different, more earthy flavor profile.
lime juice - Substitute with lemon juice: Lemon juice provides a similar acidity and brightness, though it has a slightly different citrus flavor.
cilantro - Substitute with parsley: Parsley offers a fresh, slightly peppery flavor that can stand in for cilantro, especially for those who find cilantro's taste soapy.

How to Store or Freeze This Recipe
Allow the charred tomato salsa / roasted tomato vinaigrette to cool completely before storing. This prevents condensation, which can affect the texture and flavor.
Transfer the cooled mixture to an airtight container. Glass jars or BPA-free plastic containers work best to maintain freshness.
Store in the refrigerator for up to one week. The flavors will meld and intensify over time, making it even more delicious.
For longer storage, consider freezing. Pour the salsa or vinaigrette into freezer-safe containers or zip-top bags. Leave some space at the top to allow for expansion as it freezes.
Label the containers with the date and contents. This helps you keep track of how long it has been stored.
When ready to use, thaw the frozen salsa or vinaigrette in the refrigerator overnight. Stir well before serving to recombine any separated ingredients.
If you prefer smaller portions, freeze the mixture in ice cube trays. Once frozen, transfer the cubes to a zip-top bag. This method allows you to thaw only what you need.
Avoid refreezing once thawed. This can degrade the quality and texture of the salsa or vinaigrette.
For an added burst of flavor, consider adding fresh cilantro or a squeeze of lime juice after thawing to brighten up the taste.
