Why it works: Parsley and lemon 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 ↓
Braised Liver
Ingredients
Directions
Prepare
Lard the liver with the salt pork.
Melt the butter in a small iron pot with a tight cover.
Braise
Add the onions, mushrooms, parsley, and lemon to the pot.
Place the liver in the pot and cover tightly to prevent steam from escaping.
Cook for 2 hours.
Serve
Remove the liver from the pot, strain the gravy, and pour it over the liver.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Forms the main dish; the long, covered braise makes it tender.
- Salt pork
- Adds fat and savoury flavour to the lean liver as it cooks.
- Butter
- Adds richness and helps brown the pot before the braise.
- Onions
- Soften and sweeten as they braise, flavouring the gravy.
- Mushrooms
- Release moisture and savoury flavour into the gravy.
- Lemon
- Adds acidity that brightens the rich, fatty gravy.
The step that matters
Cover the pot tightly for the full 2 hours. Liver is lean and toughens and dries if it cooks in open steam. A tight lid traps moisture so the braise stays juicy and the gravy stays concentrated.
