Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Ragout of Roast Pig
Ingredients
Directions
Prepare the sauce and pig
In a saucepan, combine gravy and mushrooms; heat to boiling.
Add butter rolled in flour to the saucepan.
Cut the slices of pig into nearly equal sizes; rub with pepper, salt, mace, and lemon peel.
Finish and serve
Place the slices into the gravy and heat until very hot, but do not boil.
Stir in the beaten eggs and lemon juice; simmer for three minutes.
Pour the mixture into a dish lined with crustless slices of fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast pig
- Forms the main body of the dish, carrying most of its savoury meaty flavour.
- Mushrooms
- Add soft texture and earthy savour that complements the meat and gravy.
- Butter
- Adds richness and, with flour, helps thicken the gravy smoothly.
- Eggs
- Thicken and enrich the sauce as they gently set with the heat.
- Gravy or stock
- Provides the liquid base and most of the sauce's savoury flavour.
- Lemon
- Adds bright acidity and aroma that cut through the richness of the sauce.
The step that matters
Keep the sauce below a boil once the eggs go in. Egg proteins set when heated, and boiling makes them tighten and curdle. Gentle heat lets the eggs thicken the sauce smoothly.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, butter, egg, lemon, parsley):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against mushroom, butter, egg, lemon, parsley. Candidates are from the same food group and used in at least 100 recipes.
