Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

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.
Prepare the meat
Fry the bacon in a pan until slightly browned.
Add the onion and fry until softened.
Add the hamburger steak and cook until thoroughly browned.
Combine and bake
Boil the spaghetti according to package instructions, then drain.
Mix the cooked bacon, onion, hamburger, and spaghetti together. Season to taste.
Pour the can of tomatoes over the mixture.
Cover and bake in a preheated oven at 350°F (175°C) for 2 hours.

What each ingredient does
- Bacon
- Renders fat that cooks the onion and meat, and adds savory, smoky flavor.
- Hamburger steak
- Provides the main meaty body and browned flavor of the sauce.
- Spaghetti
- Forms the starchy base that absorbs the sauce and holds the dish together.
- Tomatoes
- Supply moisture and acidity that build the sauce during long baking.
- Chili powder
- Adds warm spice and depth to the meat and tomato mixture.
The step that matters
Thoroughly brown the hamburger steak. Browning meat through the Maillard reaction creates deep savory flavor. Pale, steamed meat stays grey and bland, and that flavor carries into the baked sauce.
