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 ↓
Irish Stew
Ingredients
Directions
In a deep kettle, layer sliced potatoes, followed by a layer of sliced onions, then a layer of mutton.
Repeat the layers, finishing with a layer of potatoes on top.
Sprinkle salt and a little flour between each layer.
Add enough water to prevent burning.
Cook slowly for four hours without stirring over a hot fire.
