Why it works: Tomato and onion 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 ↓
Spam Pizza
Ingredients
Directions
Make the dough
Mix the sourdough starter, flour and salt together (adding a bit of flour at a time until it takes shape but is still a little sticky) and knead the dough for about 30 seconds.
Place the dough in a lightly floured bowl and cover with a towel, set aside for 1 hour.
Prepare the toppings
Slice Spam into eighths.
Slice onion and tomatoes.
Grate mozzarella.
Shape and bake
Place the pizza stone in the oven and preheat to 550 degrees for 1 hour.
Flour a surface and roll out the dough.
Put a floured pizza peel underneath the dough.
Add sauce, cheese, and toppings.
Pat down the toppings before putting into the oven.
Bake pizza in the oven at 550 degrees F. for 8-10 minutes.
Remove pizza from oven with pizza peel and let cool for 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sourdough starter
- Ferments and leavens the dough, giving it rise and a tangy flavor.
- Bread flour
- Provides the gluten structure that holds the dough together and lets it stretch.
- Mozzarella
- Melts and browns on top, adding richness and a stretchy texture.
- Tomato sauce
- Adds moisture and acidity that give the pizza its base flavor.
The step that matters
Preheat the pizza stone fully. A stone that is fully heated delivers strong bottom heat right away, which crisps the crust and helps prevent a soggy, pale base.
Swap the onion
How well each one fits the dish's main ingredients (tomato, sauce, bread, flour):
