Tips for the Best Texture and Flavor in Tomato Cucumber Recipes

• Letting the salad sit for at least 1 hour deepens the flavor dramatically

These tips make a simple cucumber salad tomato dish taste like something you’d find in a country farmhouse kitchen.

FAQ: Tomatoes Cucumbers and Onion Salad Essentials

Can I use other types of vinegar?
Yes. White wine vinegar, apple cider vinegar, or red wine vinegar all work well.

What’s the best tomato for this salad?
Firm varieties like Roma, grape, or cherry tomatoes work best. They hold their shape and soak up flavor.

Can I use white onion instead of red?
You can, but red onion provides better color and a milder bite. White onions can be stronger and should be soaked first.

Absolutely—add sliced jalapeños or a pinch of crushed red pepper flakes to the marinade.
