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 ↓
Vegetable Pot Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Wash the lima beans and soak them in water.
Add more water, celery, onion, salt, and pepper.
Cook on low heat until done.
Assemble
In a large baking dish, layer the beans, corn, tomatoes, and parboiled, sliced potatoes.
Repeat layers until the dish is almost full.
Mix 1 cup of milk with 1 tablespoon of flour until smooth.
Pour the milk‑flour mixture over the layers.
Bake and top
Bake in a 400°F (200°C) oven for 30 minutes.
Top with baking powder biscuits.
Bake for an additional 15 minutes or until golden brown.
