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 body of the stew, becoming tender with gentle simmering.
- Flour
- Browned in fat, it thickens the water into a gravy-like sauce.
- Dripping
- Fat for browning the flour and adds rich flavour to the gravy.
- Onion
- Softens during simmering and adds sweetness and aroma to the sauce.
The step that matters
Stirring the flour as it browns. Flour browned in fat develops nutty flavour and colour, but if it scorches it turns bitter. Keep it moving over steady heat, then stir constantly when adding water so lumps do not form.
