2 quartsIngredients
Directions
Prepare the vegetables
In a large stewpan or thick iron saucepan, melt the butter until it is about to brown.
Add the sliced onions, diced vegetable marrow, cucumbers, and acid apples.
Stir often and cook over gentle heat until the vegetables are tender.
Mix in the curry powder and salt, then let the vegetables stew for 20 to 30 minutes.
Gradually add enough boiling water to just cover the vegetables.
Strain and finish
When the mixture is nearly a pulp, press it through a fine sieve with a wooden spoon.
Heat the strained mixture in a clean stewpan, adding enough liquid to make 2 quarts.
Adjust seasoning with salt, cayenne, or acid as needed, and serve extremely hot.
If butter appears on the surface, skim it off or stir in arrowroot mixed with a little cold broth or water to thicken.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and rich flavour as the vegetables begin to cook.
- Vegetable marrow
- Forms the bulk of the soup and breaks down into a smooth body.
- Cucumbers
- Contribute moisture and a mild, fresh vegetable base once stewed.
- Acid apples
- Add tartness that balances the curry powder and the sweetness of the onions.
- Mild curry powder
- Supplies the spiced aroma that defines the soup.
The step that matters
Stewing the vegetables gently with the curry powder. Over high heat the onions and butter can scorch and turn bitter, and the curry powder can burn, spoiling the flavour. Gentle heat with frequent stirring softens the vegetables evenly and lets the spices bloom without catching on the pan.
Swap the arrowroot
