Another version of pumpkin soup

There is a reference to pumpkin soup in a list of my mother's which I discovered at random. She also refers to spiced pumpkin soup in her account of Christmas 1990. Here, in her book of recipes, is what I think she was referring to:

"1 young and soft skinned small pumpkin, peeled & cubed (scrape off coarse fibres in middle).
1 large onion.
2 spring onions & greens.
1 level teaspoon curry powder.
2 beef stock cubes.
1 large can chopped tomatoes.
Olive oil/butter.

Fry chopped onions & pumpkin in butter/olive oil gently. Sprinkle on curry powder & fry until curry powder cooked through. Add tomatoes & stock cubes & 1/2 pint water. Simmer until pumpkin soft. Liquidise & add water until right consistency. Salt/freshly ground black pepper to taste."
