Why it works: Butter and mushroom 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 ↓
Beef in Stout
Ingredients
Directions
Prepare
Preheat the oven to 180 °C / 350 °F / Gas 4.
Brown and soften
Heat the butter and oil in a large flame-proof casserole and cook the meat for 10 minutes, until browned all over. Remove from the pan with a slotted spoon.
Add the onions and mushrooms to the pan and fry until softened. Add the flour and stir well so that the flour absorbs the fat.
Braise and serve
Return the meat to the pan, add the stout, bay leaf and sugar. Stir well.
Cover and cook in the oven for about 2 hours or until the meat is tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewing steak
- Becomes tender during long, slow cooking, giving the stew its main body and bite.
- Plain flour
- Absorbs the fat from the pan and thickens the cooking liquid into a rich sauce.
- Stout
- Forms the cooking liquid, adding depth and a roasted, bitter aroma to the stew.
- Onions
- Soften and sweeten as they cook, adding body and flavour to the sauce.
- Button mushrooms
- Release moisture and savoury flavour into the sauce as they fry and braise.
The step that matters
Browning the meat. Searing the meat in hot fat over direct heat creates browned flavour through the Maillard reaction. Crowding the pan or stopping early steams the meat, leaving the stew pale and flat-tasting.
Swap the onion
How well each one fits the dish's main ingredients (butter, mushroom, flour, sugar):
- Shallotfits better
- Arrowrootfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against butter, mushroom, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
