Make Ahead: Gazpacho tastes best made at least 2 hours ahead, and ideally the night before. The flavors deepen and meld beautifully with time. Storage: Store in an airtight container in the refrigerator for up to 4 days. Stir well before serving. Do not freeze. Tomato Tip: Use the ripest, most flavorful tomatoes available. Peak-season heirloom or vine-ripened tomatoes produce the most vibrant, flavorful result. Vinegar: Sherry vinegar is traditional and provides the most nuanced flavor. Red wine vinegar is a good substitute. Apple cider vinegar works in a pinch but will change the flavor profile slightly. Texture: For a silkier soup, strain through a fine-mesh sieve. For a chunkier texture, blend less and skip straining. Serving Suggestion: Serve in chilled bowls or even tall glasses as a refreshing starter shot.
