Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Lentil 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.
Make the filling
Melt the butter in a skillet and fry the diced potatoes and onion until nearly soft.
Add the sliced tomatoes, cooked lentils, herbs, and seasoning to the skillet and mix well.
Transfer the mixture to a pie dish and add enough water or vegetable stock to create gravy.
Assemble and bake
Arrange the quartered hard-boiled eggs on top.
Cover with a short crust and bake at 350°F (175°C) for 1 to 1½ hours.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

What each ingredient does
- Lentils
- Form the bulk of the filling and give it a hearty, substantial texture.
- Potatoes
- Soften during frying and add starch that thickens the filling and gives body.
- Tomatoes
- Add moisture and a mild acidity that brightens the savoury filling.
- Butter
- Adds fat for frying the vegetables and rich flavour.
- Eggs
- Add richness and set into firm pieces through the baked filling.
