Mushrooms on Toast

Ingredients

Directions

Prepare the mushrooms

Wash the mushrooms carefully and peel them with a silver knife.
Divide the mushrooms into quarters and soak them in cold water with a little vinegar.

Cook

In a saucepan, melt the butter over low heat.
Add the mushrooms, water, and salt to the saucepan, cover, and cook slowly for 10 minutes until tender.
Divide the cream into two portions; add one portion to the mushrooms.
Mix the remaining cream with the flour and add it to the mushrooms, stirring until very hot.

Serve

Serve the mushroom mixture on toasted bread or biscuits.

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

What each ingredient does

Meadow mushrooms: Provide the main body and earthy flavour of the dish.
Cream: Adds richness and moisture, giving the mixture a smooth, rich texture.
Flour: Thickens the cream as it heats, so the mixture becomes smooth and coats the mushrooms.
Butter: Adds fat and flavour for gently cooking the mushrooms.

The step that matters

Adding the flour and cream mixture. Flour must be blended smoothly into cream before it goes in, otherwise it clumps. Stirring as the mixture heats lets the starch swell and thicken evenly into a smooth sauce.
