Oyster Plant

Ingredients

Directions

Prepare

  1. Scrape the roots and place them in cold water immediately to prevent blackening.

  2. Cut the roots into 1‑inch pieces and place them in a saucepan with hot water to cover.

Cook and serve

  1. Stew until tender, then drain the water.

  2. Add enough soup, stock, or milk to cover the salsify and stew for 10 minutes after it begins to boil.

  3. Add a large lump of butter cut into bits and rolled in flour, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salsify
Is the main vegetable, becoming tender and mild when stewed.
Butter
Adds richness and fat, giving the stew a smooth, silky body.
Flour
Coats the butter so it thickens the liquid as it melts into the stew.
Soup, stock, or milk
Forms the cooking liquid that gives the stew its savoury flavour and body.

The step that matters

Add the butter and flour rolled in flour. Butter and flour added at the end thicken the liquid when it melts and stirs in. If the butter is added in one large lump without being worked in, the sauce may be uneven and greasy rather than smooth.
