Balsamic Tomato Bruschetta Topping

This recipe makes only the fresh, balsamic-dressed tomato mixture, so the bread can be prepared separately and stay crisp. Spoon it onto crisp baguette slices just before serving, or use it over grilled chicken, beans, pasta, or salad.

Although any ripe, firm tomato can work in this mixture, this recipe calls for Roma tomatoes. Roma and other paste-type tomatoes have firm, meaty flesh, fewer seeds, and less juice than many slicing tomatoes, so they make a substantial topping without releasing as much water.

Needed equipment

• Knife and cutting surface
• Medium bowl
• Measuring cups and spoons
• Spoon for mixing

Optional equipment

• Colander, fine-mesh strainer, or cheesecloth for draining especially juicy tomatoes
• Garlic press for preparing the garlic quickly

Ingredients

• 6 Roma tomatoes, cored and chopped into 1/4-inch pieces
• 1 tablespoon minced garlic
• 1/4 cup chopped fresh basil
• 1/4 cup chopped red onion
• 1/8 cup (2 tablespoons) olive oil
• 1/2 tablespoon salt
• 1 tablespoon ground black pepper
• 4 tablespoons balsamic vinegar

Instructions

1. Rinse and dry the tomatoes. Cut a thin slice from the stem end of each tomato, then quarter it lengthwise.

2. Cut the tomato quarters into roughly 1/4-inch pieces. Put them in the bowl, leaving excess juice on the cutting board so the finished topping does not immediately soak the bread.

3. Rinse and dry the basil. Remove any thick stems, gather the leaves, and chop them. Add the basil, minced garlic, and chopped red onion to the tomatoes.

4. Toss gently until the basil, garlic, and red onion are distributed through the tomatoes.

5. Pour in the olive oil and balsamic vinegar. Stir until every piece of tomato looks lightly coated.

6. Add the measured salt and pepper gradually, mixing and tasting as you go. Stop when the tomato flavor is bright and savory; reserve any seasoning that would make the mixture taste harsh or overly salty.

7. Let the mixture rest for 10 to 15 minutes at room temperature. Stir once more, then taste and adjust the vinegar, oil, salt, or pepper if needed.

8. Use a slotted spoon to transfer the topping onto crisp baguette slices immediately before serving. This leaves the released tomato liquid in the bowl and helps the bread stay crisp.

Sensory indicators

Look

The tomatoes should hold their shape while releasing a small amount of rosy, seasoned juice. Bits of basil and red onion should be distributed throughout the mixture.

Oil and vinegar naturally separate after the mixture sits. Small pools of olive oil on the surface are normal; stir with a spoon or rubber spatula before serving. For a more polished look and a sweeter, more concentrated balsamic flavor, drizzle a small amount of balsamic glaze over the topped baguette slices.

Smell

The mixture should smell fresh and aromatic, balancing basil and garlic with the tang of balsamic vinegar.

Taste

It should taste bright and savory, with balsamic tang supporting the tomatoes rather than hiding or overpowering them.

Common mistakes

Too salty

Adding all the salt at once can draw a large amount of water from the tomatoes and make the topping too salty. Start with half the measured salt, let the mixture rest, and add more only after tasting.

If the mixture is too salty, fold in an additional chopped fresh tomato. Plain, no-salt-added canned diced tomatoes can work in an emergency, but canned tomatoes are heat-processed and softer than fresh tomatoes. Drain them thoroughly before adding them.

Too watery

Salt and resting naturally draw juice from chopped tomatoes. If the mixture becomes too watery, drain it briefly and serve it with a slotted spoon. Leave a little seasoned liquid behind so the topping does not taste dry.

Soggy bread

Do not top the bread far in advance. Tomato juice will soften even well-toasted slices. Serving the toast and tomato mixture separately preserves the toast's crispness.

Substitutions

Any ripe, firm tomato can replace Roma tomatoes; scoop out some seeds from especially juicy varieties. AnotherBudgetGamer uses whichever garden tomatoes are ripe, including:

• Cherry or grape tomatoes
• Beefsteak tomatoes
• Brandywine tomatoes
• Favorite hybrid varieties

Garlic powder can replace fresh garlic, though its flavor will be softer and less pungent. Start with 1/2 teaspoon, let it hydrate in the mixture, then add more to taste.

Red wine vinegar can replace balsamic for a sharper, less sweet result.

Dried basil is not a direct substitute for fresh basil. The general conversion is 1 teaspoon dried herbs for every 1 tablespoon fresh herbs, which makes 4 teaspoons dried basil equivalent to the recipe's 1/4 cup fresh basil. Because dried basil can taste stronger and less bright in an uncooked topping, start with 2 to 3 teaspoons, let the mixture rest for a few minutes, then taste and adjust.

Shredded mozzarella can be added to the baguette slices in place of fresh mozzarella. If no mozzarella is available, a tangy cheese such as feta or goat cheese also works.

Sun-dried tomatoes can be added for concentrated sweetness and richness, but they are not a one-for-one replacement for fresh tomatoes. If using oil-packed sun-dried tomatoes, drain and chop them, then reduce the fresh olive oil as needed.

Storage and reheating

Serve the mixture after its 10- to 15-minute rest, or refrigerate it for up to 1 hour before serving if you prefer it chilled. Keep it in a covered container at 40°F or below and use it within 3 days.

It is best the day it is made. Refrigerate the cut-tomato mixture within 2 hours, or within 1 hour when the temperature is above 90°F. Stir before serving and drain excess liquid as needed. Do not reheat; after refrigeration, let it sit at room temperature for 15 to 20 minutes so the olive oil loosens and the tomato flavor becomes more noticeable.

Variations

Add red pepper flakes for heat or small cubes of mozzarella for a more substantial topping. For a sweeter finish, reduce the balsamic vinegar slightly; for more acidity, add it a teaspoon at a time after the mixture rests.
