Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Orange Pepper Frittata with Fresh Thyme
Ingredients
Directions
Prepare
Beat eggs, milk and cheese in a large bowl, then stir in salt and pepper and set aside.
Melt butter with olive oil in a medium skillet over medium‑high heat.
Add onion and bell pepper and sauté until onion is translucent.
Reduce heat to medium and cook until pepper is soft.
Cook the frittata
Pour egg mixture over the vegetables.
Reduce heat to low and cook until eggs are firm around the edges.
Lift edges of the eggs with a spatula and tilt pan to let uncooked eggs run under cooked eggs.
Cook until eggs are almost set on top, about 5 minutes more.
Invert a plate on top of the pan.
Hold plate and pan firmly together with pot holders and invert.
Slip the frittata cooked side up back into the pan.
Cook 2 minutes more.
Invert a serving plate over the pan and invert as before.
Finish and serve
Sprinkle with thyme.
Serve hot or at room temperature.
Cut into wedges.
Drizzle with extra‑virgin olive oil.
Season with salt and pepper.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a custardy structure that holds the frittata together when cooked.
- Parmesan cheese
- Adds savory, salty flavor and helps the eggs brown lightly at the surface.
- Milk
- Adds moisture and softness to the egg mixture, keeping the frittata tender.
- Bell pepper
- Contributes sweetness and moisture as it softens in the butter and oil.
- Butter
- Adds richness and flavor and helps keep the eggs from sticking to the pan.
The step that matters
Cook the eggs over low heat and flip with a plate. Eggs cooked too hot toughen and brown or scorch before the centre sets. Low heat lets the proteins set gently, and the plate flip lets the top cook through without breaking the frittata.
