Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Ravioli
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 dough
In a bowl, mix flour, eggs, and salt to form a dough.
Roll the dough until it is as thin as parchment.
Cut the dough into circular pieces, 3-4 inches in diameter.
Fill and seal
Place a portion of forcemeat on each piece.
Fold the dough over and pinch the edges to seal.
Bake and serve
Place the ravioli in a deep dish, pour broth over them, and sprinkle with Parmesan cheese.
Bake in a preheated oven at 350°F (175°C) for 20-30 minutes.
Serve the dish without disturbing the ravioli.

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the gluten network that gives the dough its structure and elasticity.
- Eggs
- Bind the dough and add richness and firmness once cooked.
- Parmesan cheese
- Melts and browns on top, adding savory flavor and a golden crust.
- Broth
- Adds moisture and flavor as the ravioli bake.
The step that matters
Pinch the edges to seal. If the dough edges are not sealed firmly, the filling can leak out during baking and the pasta can open up. A tight seal keeps the forcemeat enclosed while it cooks.
