Why it works: Thyme and pepper are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 11,585 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Egg Plant Au Gratin
Ingredients
Directions
Prepare the filling
Boil 2 eggplants for 20 minutes.
Cut lengthwise, scoop out the center, mash, and mix with ½ cup bread crumbs, ½ teaspoon thyme, 1 teaspoon vinegar, 1 teaspoon onion juice, salt and pepper to taste, ¾ cup finely chopped salt pork, and 1 tgg.
Add 2 tablespoons melted butter to the mixture, and cook for 5 minutes, stirring constantly.
Bake
Pour into a baking dish, cover lightly with bread crumbs and small bits of butter, and bake slowly for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggplant (in the method)
- Forms the bulk of the filling and gives a soft, moist base once cooked.
- Bread crumbs
- Absorb moisture and help bind the mashed filling, and form a crisp topping.
- Egg
- Binds the filling so it sets firm when baked.
- Salt pork
- Adds fat and savory flavor that carries through the filling.
- Butter
- Adds richness and helps the top brown during baking.
The step that matters
Cook the mixture while stirring constantly. Stirring keeps the mashed eggplant and fat from scorching on the bottom of the pan and helps the filling cook evenly before baking.
