Method
Finely dice the cherry tomatoes, mince the shallot, and finely chop the fresh basil leaves. Keep the basil separate to prevent oxidation.
In a medium mixing bowl, combine the diced tomatoes, minced shallot, white wine vinegar, Dijon mustard, and kosher salt.
Allow the tomato mixture to rest at room temperature. The salt will draw out the natural juices from the tomatoes, creating a flavorful liquid base.
While whisking the tomato mixture continuously, slowly drizzle in the extra virgin olive oil until the dressing is fully incorporated and slightly thickened.
Gently fold in the chopped fresh basil and black pepper. Taste the vinaigrette and add a small pinch of additional salt if needed to balance the acidity.
Chef's Notes
- For the best flavor, use ripe, seasonal tomatoes. If out of season, cherry or grape tomatoes consistently offer the best natural sweetness.
- Do not prepare this vinaigrette too far in advance; the fresh basil will oxidize and turn dark if left sitting in the acidic vinegar for more than a few hours.
- When serving over hot fish, spoon the room-temperature vinaigrette over the protein right at the table. The residual heat of the fish will release the aromatic oils of the basil.
- The Dijon mustard is crucial not just for flavor, but for structure. It acts as a natural emulsifier, helping the oil and vinegar bind together into a cohesive sauce.
Storage
Refrigerator: 2 days — Store in an airtight container. Bring to room temperature before serving, as olive oil may solidify when chilled.
