Why it works: Onion and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 21,599 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
10 servingsIngredients
Contains: egg, peanut, tree nuts, soy (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the vegetable oil in a large saucepan over medium heat. Add the onion, carrot and mushrooms and cook, stirring often, for 8 minutes until soft and lightly browned.
Stir in the vegetable broth, dry red lentils and steel cut oats. Bring to a boil, then reduce the heat to low, cover and simmer for 25 minutes, stirring now and then, until the oats are tender and most liquid is absorbed.
Remove the pan from the heat. Stir in the mashed kidney beans, ground peanuts, ground hazelnuts, soy sauce, lemon juice, dried thyme, dried rosemary, cayenne pepper and mixed spice until evenly combined.
Let the mixture cool for 5 minutes, then stir in the beaten egg until fully blended.
Preheat the oven to 350°F (175°C). Line a loaf pan or small baking dish with foil and press the mixture firmly into it.
Set the dish in a larger pan with boiling water poured around it to halfway up the sides. Bake for 25 minutes until firm and an instant-read thermometer reads 160°F (71°C) in the center.
Let stand for 10 minutes, then lift out using the foil and slice to serve.

Fit is the average pairing score against onion, carrot, mushroom, lentils, peanut, hazelnut, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
