Why it works: Carrot and potato match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,107 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Minced Beef or Shepherd’s Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a skillet, cook the minced beef until browned.
Add the vegetables and cook until tender.
Season with salt and pepper.
Assemble and bake
Transfer the beef mixture to a baking dish.
Spread the mashed potatoes on top.
Dot with butter and bake for 30 minutes until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced beef
- Browns in the pan to build savory flavor and forms the body of the filling.
- Vegetables
- Add moisture, sweetness and texture to the filling as they soften while cooking.
- Mashed potatoes
- Form a soft topping that browns in the oven, adding a golden crust.
- Butter
- Adds richness and helps the potato topping brown in the oven.
The step that matters
Browning the minced beef. Cooking the beef until well browned develops deep savory flavor through the Maillard reaction. Pale, steamed meat leaves the filling tasting flat and greyish.
Swap the peas
How well each one fits the dish's main ingredients (beef, carrot, potato, pepper, butter):

Fit is the average pairing score against beef, carrot, potato, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
