How to Cook Cucumbers

Ingredients

Directions

Prepare the cucumbers

  1. Peel and slice the cucumbers thickly, then remove the seeds.

  2. Boil the cucumbers in water with salt until tender, then drain well.

Make the sauce

  1. In a separate pan, melt the butter and mix in the flour to form a cream.

  2. Add the reserved boiling water to the butter-flour mixture and stir until thickened.

  3. Season with salt, pepper, and lemon juice.

Serve

  1. Pour the sauce over the cucumbers and serve hot on toast.

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

What each ingredient does

Cucumbers
Make up the bulk of the dish and supply the main body and moisture of the sauce.
Butter
Enriches the sauce with fat and a smooth, rich mouthfeel.
Flour
Thickens the butter and boiling water into a smooth, stable sauce.
Lemon juice
Adds acidity that brightens the flavour and balances the richness of the butter.

The step that matters

Stirring the flour into the butter and adding the water. Cooking the flour in melted butter makes a roux that thickens smoothly. Adding boiling water gradually while stirring prevents lumps, since starch clumps when it hits liquid unevenly.

Swap the cucumber

How well each one fits the dish's main ingredients (butter, flour, pepper, lemon):

  1. Shallotfits better
  2. Arrowrootfits better
  3. Okrafits better
  4. Cucumberthe original

Fit is the average pairing score against butter, flour, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
