Summer Tomato Salad
Ingredients
Directions
Make the vinaigrette
Place the onions in a small mixing bowl.
In a small saucepan, bring the vinegar just to a boil. As soon as it reaches a boil, pour it over the onions.
Let it sit until it cools.
When cool, drain the vinegar from the onions into a food processor or blender.
With the machine running, add the olive oil in a slow, steady stream until all of the oil has been added and the mixture is pale and creamy.
Add season salt and pepper.
Assemble and serve
Place the tomato slices on each serving plate.
Arrange the onions on top of the tomatoes and sprinkle the cheese over the onions.
Drizzle 2 tablespoons of the vinaigrette on each just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red onion
- Its sharp flavour is mellowed by the hot vinegar and adds bite to the dressing.
- Distilled white vinegar
- Provides the acidity that gives the vinaigrette its tang and balances the oil.
- Olive oil
- Emulsifies with the vinegar and onion to make the dressing pale, creamy and rich.
- Vine-ripened beefsteak tomatoes
- Supply the juicy, sweet body of the salad that the dressing coats.
- Mozzarella cheese
- Adds mild, creamy richness that softens the acidity of the dressing.
The step that matters
Adding the olive oil slowly while the machine runs. Adding oil in a slow, steady stream lets it disperse into the vinegar as tiny droplets, forming a stable emulsion. Pouring it in quickly can make the dressing separate into oily and watery layers.
