Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
A Nice Ragout From Cold Lamb
Ingredients
Directions
Prepare the lamb
Remove the lamb from the bones and cut it into convenient pieces.
Lard the lamb with the fried bacon and stew it lightly in mutton gravy until covered.
Season with sweet herbs, pepper, coarse sea salt, and spice.
Make the sauce
Strain off the gravy, keeping the meat hot.
Add oysters, port wine, mushrooms, and butter rolled in flour to the gravy.
Add the lemon juice and boil together for a few minutes.
Serve
Pour the sauce over the lamb before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold lamb
- Forms the bulk of the ragout, providing the meat that the sauce coats.
- Bacon
- Adds fat and savoury flavour as it is larded into the lamb.
- Butter
- Rolled in flour, it thickens the gravy into a smooth, glossy sauce.
- Port wine
- Adds sweetness and depth of flavour to the sauce as it reduces.
- Oysters
- Contribute a briny, savoury flavour that enriches the sauce.
- Lemon juice
- Adds acidity that brightens the rich gravy and balances the fat.
The step that matters
Adding the butter rolled in flour to the gravy. Flour must be fully dispersed in the hot liquid, or it forms lumps. Boiling for a few minutes after adding it cooks out the raw flour taste and lets the sauce thicken evenly.
