Why it works: Flour and lemon are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 30,404 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid into a smooth, lightly bodied sauce as it cooks.
- Beef suet
- Adds richness and fat, giving the sauce a rounder, more savoury mouthfeel.
- Lemon juice
- Adds acidity that brightens the sauce and helps keep the oyster plant pale.
- Oyster plant (salsify)
- Provides the main vegetable, which turns tender through slow simmering.
The step that matters
Simmer the oyster plant slowly until tender. Vigorous boiling breaks up the vegetable and cloudies the sauce, while gentle simmering lets starch and fibres soften evenly. Checking for tenderness prevents both undercooked centres and mushy pieces.
