Ingredients
Directions
Prepare the tomatoes
Chill the tomatoes in the refrigerator until very cold, but not frozen.
Remove the skins from the tomatoes without using hot water and slice them while keeping their shape.
Marinate and dress
Marinate the tomato slices by dipping them in a mixture of 3 tablespoons vinegar, 1 tablespoon oil, pepper, and coarse sea salt.
Drain and mix with mayonnaise sauce.
Arrange and serve
Arrange the tomato slices on a serving dish in a uniform order.
Top each tomato slice with a spoonful of thick mayonnaise sauce.
Garnish the dish with parsley or other leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and juice of the salad, and their flavour carries the dish.
- Mayonnaise sauce
- Adds richness and a creamy fat coating that softens the sharp tomato acidity.
- Vinegar
- Adds acidity that brightens the tomatoes and balances the richness of the mayonnaise.
- Oil
- Adds fat that carries flavour into the tomato slices during marinating.
The step that matters
Chill the tomatoes until very cold, but not frozen. Cold firms the flesh so slices hold their shape when peeled and cut. Freezing would damage the cell walls, leaving the tomato mushy and watery once thawed.
Swap the tomato
How well each one fits the dish's main ingredients (sauce, vinegar, pepper, parsley):
- Capsicumfits better
- Shallotfits better
- Mustardfits better
- Tomatothe original
Fit is the average pairing score against sauce, vinegar, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
