Why it works: Butter and parmesan cheese are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,163 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Paste Soup
Ingredients
Directions
Make the paste
In a bowl, rub together the butter and baked flour until perfectly mixed.
Beat the yolk of egg and stir it into the flour mixture.
Knead the mixture into a stiff paste and roll it out as thin as a shilling.
Cut the paste into strips, each 1 inch long and ⅛ inch wide.
Set the strips in a cool, airy place for 5 to 6 hours.
Cook and serve
Boil the cold water in a pot.
Add the paste to the boiling water and cook for 20 minutes.
Grate and add the Parmesan cheese and Marsala wine before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh butter
- Adds richness and fat, giving the paste a tender texture and flavour.
- Baked flour
- Provides the starch and structure that hold the paste together.
- Yolk of egg
- Binds the dough and adds richness to the paste.
- Parmesan cheese
- Adds salty, savoury flavour to the finished soup.
- Marsala wine
- Adds a sweet, aromatic depth of flavour to the soup.
The step that matters
Rolling and resting the paste. Rolling the paste very thin and letting the strips rest lets the dough dry slightly and firm up, so the pasta holds its shape and cooks evenly in the water rather than turning gummy or breaking apart.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
