Why it works: Parmesan cheese and cheese match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 1,041 recipes. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
Macaroni Au Jus
Ingredients
Directions
Prepare
Pour off all the water from the macaroni.
Place the macaroni in a stewpan with 1 pint of stock.
Add ½ teaspoon of coarse sea salt and ¼ teaspoon of black pepper.
Cook and thicken
Simmer until the macaroni is tender, about 25-30 minutes for Neapolitan or 50-60 minutes for Genoese.
Test the macaroni by trying a small piece.
If needed, strengthen the remaining stock with 1 teaspoon of Liebig’s Extract of Meat.
Thicken the stock with baked flour until desired consistency.
If desired, stir in 1 ounce of grated Parmesan and ½ ounce of English cheese during the last half of cooking.
Serve
Add a pat of butter and sprinkle with Parmesan before serving.
Serve hot, optionally with tomato sauce on top or on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the body of the dish and absorbs the stock as it cooks.
- Beef or veal stock
- Provides the liquid and savoury meat flavour that the whole dish is built on.
- Baked flour
- Thickens the stock so it clings to the macaroni.
- Parmesan cheese
- Adds salty, savoury flavour and richness to the stock and finished dish.
- Butter
- Adds fat and a smooth, rich mouthfeel to the finished dish.
The step that matters
Thicken the stock with baked flour. Flour must be fully mixed in and cooked through, or it stays lumpy and tastes raw. Starch thickens the liquid only as it heats, so add it gradually and simmer until the stock reaches the desired consistency.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (beef, pepper, meat, flour, parmesan cheese, cheese, butter):
