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 ↓

Ingredients
Directions
Prepare
Strew bacon over the hare after removing excess fat.
Layer hare and bacon in a jug, then add ale.
Cook
Cover the jug tightly and place it in a kettle of cold water.
Add a lid on top and boil for 3 hours for young hare, or 4-5 hours for older hare.
Finish the gravy
Shake the hare in a stewpan with mushroom ketchup, port wine, mushroom powder, butter, and flour to thicken the gravy.
Add lemon-pickle and browning to enhance flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Adds fat and savoury flavour that seasons the meat and the gravy.
- Flour
- Thickens the gravy as it cooks with the butter and juices.
- Butter
- Adds richness and helps the flour form a smooth, thickened gravy.
- Port wine
- Adds sweetness and depth to the gravy.
- Ale
- Moistens the meat and adds malty flavour during slow cooking.
The step that matters
Keep the jug sealed and the water gently boiling. A tightly covered jug traps moisture so the meat braises in its own juices rather than drying out. Long, gentle heat breaks down the connective tissue in the hare, so it turns tender instead of tough.
