All you need is:
1 large marrow
1 medium potato
1 medium onion
2 chicken or vegetable stock cubes
3 cups of water
All you do is:
Peel, core and dice marrow. Peel and dice potato and onion.
Boil them in large pot with 3 cups of water and stock cubes until veg is soft.
Either blend with a stick blender or just use a potato masher depending if you want it smooth or chunky.
If it's a bit bland you could always add some paprika or chilli flakes, once served, to give it a bit of a kick.
The best thing about this soup is that it's all come from my allotment. Don't forget to save some of the marrow seeds for next year. Till next time and thanks for reading.
