Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Heighten the Colour and the Flavour of Gravies
Ingredients
Directions
Prepare
Dice an ounce or two of lean unboiled ham.
In a small stewpan or iron saucepan, add less than an ounce of butter, a blade of mace, two or three cloves, a bay leaf, a few sprigs of savoury herbs, an eschalot or two (or about a teaspoonful of minced onion), and a little young parsley root.
Make the gravy
Cook the ham and aromatics slowly until the side of the stewpan is coloured a reddish brown.
Stir in a teaspoonful of flour, and simmer for three or four minutes before adding the stock.
Gradually add the stock (common shin of beef stock or strong broth) after the ham has stewed slowly for about half an hour, then boil with them for twenty minutes or more.
Shake the pan strongly after adding the stock to detach the browning, and repeat often while the ham is stewing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham (in the method)
- Provides the meaty flavour and the browned residue that colours and seasons the gravy.
- Butter
- Fat that cooks the ham and aromatics and helps the browning begin.
- Flour
- Thickens the gravy as it cooks in the fat and stock.
- Cloves
- Adds warm aromatic flavour to the gravy base.
- Onion
- Adds savoury sweetness and aroma as it softens and browns.
- Stock (in the method)
- Forms the liquid base of the gravy and carries the flavour of the ham and aromatics.
The step that matters
Browning the ham and aromatics. If the ham and aromatics are cooked too hot or too briefly, they burn or stay pale. Slow cooking to a reddish brown builds colour and flavour through browning reactions, which the stock then lifts from the pan.
