Why it works: Tarragon and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 824 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Ingredients
Directions
Prepare the tomatoes
Arrange the tomatoes in a shallow copper tourtiere, closely together.
Remove each tomato, cut off one-third of the top, and place them face down on a plate with a pinch of coarse sea salt for 3 hours to exude acid juice.
After 3 hours, place the tomatoes back in the tourtiere with 2 teaspoons of oil at the bottom.
Stuff and cook
Fill each tomato with the stuffing made from chopped hard-boiled eggs, tarragon, chervil, breadcrumbs, cooked onions, and garlic.
Cover the tourtiere and set it on a charcoal fire covered with ashes.
Let it stew gently for 2 to 2.5 hours until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the dish's body; salting draws out acid juice and moisture as they stew.
- Hard-boiled eggs
- Bind the stuffing and add richness and a firm, sliceable texture.
- Breadcrumbs
- Absorb liquid and give the stuffing body so it holds its shape.
- Cooked onions
- Add savoury sweetness and depth of flavour to the stuffing.
The step that matters
Salting the tomatoes for 3 hours. Salt draws acid juice and moisture out of the tomato flesh. Skipping or shortening this rest leaves a watery filling and a less concentrated tomato flavour after gentle stewing.
Swap the onion
How well each one fits the dish's main ingredients (tomato, egg, tarragon, chervil, garlic):
- Chivefits better
