Cucumbers in Milk

Ingredients

2 cucumbers, peeled and cut into small squares
¼ teaspoon coarse sea salt
water, as needed
1 pint milk
2 tablespoons all-purpose flour

Directions

Cook the cucumbers

Place the cucumbers in a saucepan over low heat.
Add salt and just enough water to prevent burning; cook until tender.

Make the milk base

In another pot, heat the milk until it boils.
Mix the flour with ½ cup of the reserved milk until smooth, then add to the boiling milk.
Stir until the mixture thickens to a cream‑like consistency.

Combine and serve

Drain the cucumbers and add them to the thickened milk mixture.
Sweeten slightly to taste and serve.

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

What each ingredient does

Cucumbers: Provide the main vegetable flavour and soft, tender pieces in the finished dish.
Milk: Forms the creamy base that thickens and gives the dish its body.
All-purpose flour: Thickens the boiling milk so it turns cream-like instead of watery.

The step that matters

Adding the flour mixture to the boiling milk. Flour must be fully smooth before it goes into the hot milk, because lumps form when starch hits heat unevenly. Stirring keeps the starch dispersed so it thickens evenly.

Swap the cucumber

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

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