Stewed Cucumbers

Ingredients

4 to 5 young cucumbers
White pepper or cayenne, to taste
Flour, for dusting
Butter, for frying
Brown gravy, enough to cover cucumbers
Optional: lemon juice, chili vinegar, or cucumber vinegar

Directions

Prepare

Peel and quarter the cucumbers, removing the seeds.
Cut each quarter in half and sprinkle with white pepper or cayenne and flour.

Fry and stew

Fry the cucumbers lightly in butter until golden.
Remove from the pan and drain on a sieve.
Place the cucumbers in a pot with enough brown gravy to nearly cover them.
Stew gently for 25 to 30 minutes until tender.

Finish the gravy

If the gravy needs thickening, remove the cucumbers and keep them warm.
Stir in a little flour and butter to the gravy to thicken it.
Add lemon juice, chili vinegar, or cucumber vinegar to taste, if desired.

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

What each ingredient does

Cucumbers: Main vegetable that softens during stewing and absorbs the flavour of the gravy.
Brown gravy: Forms the cooking liquid, supplying savoury depth and moisture for the stew.
Flour: Dusted on the cucumbers to help them brown, and stirred into the gravy to thicken it.
Butter: Fat for frying that gives the cucumbers golden colour and a rich, nutty flavour.

Swap the cucumber

The recipe marks cucumber as optional. How well each one fits the dish's main ingredients (white pepper, flour, butter, lemon):
