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, salt, and pepper.
Simmer and test
Simmer until the macaroni is tender, about 50-60 minutes for Genoese or 25-30 minutes for Neapolitan.
Test the macaroni by trying a small piece.
If needed, strengthen the remaining stock with ½ teaspoon of Liebig's Extract of Meat and thicken with baked flour.
If desired, stir in grated Parmesan and English cheese during the last half of cooking.
Finish and serve
Add a pat of butter towards the end 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 main body of the dish and absorbs the stock as it cooks.
- Beef or veal stock
- Cooks the pasta and supplies the savoury liquid that flavours it.
- Parmesan cheese
- Adds savoury, salty depth and helps the dish taste rich when stirred in or sprinkled on top.
- Butter
- Adds fat and a smooth, rounded richness to the finished dish.
The step that matters
Testing the macaroni for tenderness. Macaroni cooked in liquid keeps softening after it leaves the heat, and the cooking time varies by style, so tasting a small piece shows when it is tender enough to serve without becoming mushy or leaving the centre firm.
