Why it works: Lettuce and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 425 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Grouse Salad
Ingredients
Directions
Prepare the grouse
Roast the grouse and cut it into neat joints.
Place the joints in a pie dish, sprinkle with salt and pepper, and pour lemon juice and olive oil over them.
Let marinate for 3-4 hours, turning and basting frequently.
Assemble the salad
Wash and dry the lettuce thoroughly, then shred it finely.
Create a deep bed of lettuce in a serving dish.
Arrange the grouse pieces on top of the lettuce.
Garnish with slices of hard-boiled egg, parsley, and savory jelly if desired.
Add a border of curled celery and additional slices of hard-boiled egg around the dish.
Make the sauce and serve
In a bowl, beat the egg yolks for 3-4 minutes, then add salt and pepper.
Gradually mix in olive oil and tarragon vinegar until the sauce reaches desired thickness.
Pour the sauce over the grouse and lettuce just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Beaten yolks emulsify the olive oil into a thick, smooth sauce.
- Olive oil
- Fat that carries flavor and gives the marinade and sauce a rich, smooth body.
- Lemon juice
- Acidity that flavors the grouse during marinating and brightens the dish.
- Tarragon vinegar
- Acidity in the sauce that balances the richness of the yolks and oil.
- Grouse
- Main protein, which is cooked first and then marinated to add moisture and flavor.
The step that matters
Gradually mixing the oil into the egg yolks. Adding oil slowly while beating lets the yolk lecithin emulsify it into a stable sauce. Adding it too fast can cause the sauce to split and become oily.
