Why it works: Beer and parmesan cheese share more aroma than cooks usually use. They rank in the top 6% of all ingredient pairs, and 37 recipes mention both. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Heat the stock to near boiling and keep it hot.
Sweat the onion in a heavy, medium saucepan with olive oil and a generous pinch of salt.
When the onions are soft and transparent, add the rice and sauté until each grain is coated.
Cook the risotto
Add the beer and heat to a simmer, stirring constantly.
When the beer is mostly absorbed, add about ⅓ to ½ cup of hot stock, stirring constantly while simmering.
Repeat this process for about twenty minutes, until most of the stock is consumed and the rice is tender.
Finish with cheese
Remove from heat, add the Parmesan cheese and stir to incorporate.
Let the cheese melt, then add the cheddar and stir to combine.
If a cheesier rice is desired, add more cheese.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arborio rice
- Its starch releases gradually during stirring, giving the risotto a creamy, thick texture.
- Vegetable stock
- Provides the liquid that the rice absorbs as it cooks, so the grains become tender.
- Parmesan cheese
- Melts into the hot rice, adding savory flavor and helping create a creamy body.
- Sharp cheddar cheese
- Adds sharp, savory flavor and extra richness as it melts into the rice.
- Beer
- Adds malty flavor and acidity as it is absorbed into the rice.
The step that matters
Adding stock gradually while stirring. Adding liquid in small amounts and stirring releases starch from the rice surface, which creates the creamy texture. Adding too much liquid at once or stopping the stirring can leave the rice soupy or unevenly cooked.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (olive, rice, beer, parmesan cheese, cheddar cheese):
- Tomatobetter flavor fit
- Potatobetter flavor fit
- Capsicumbetter flavor fit
- Onionthe original
Fit is the average pairing score against olive, rice, beer, parmesan cheese, cheddar cheese. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
