Managed to leave a courgette on the plant long enough to become a four pound marrow and decided to make this soup.

not my marrow
1 large bulb of garlic, seperated into cloves, root end cut off but not skinned. Roasted in oven in a couple of tablespoons of oil for about 20 minutes.
1 large onion, chopped and sweated in a large saucepan in a tablespoon of oil (and optional butter)
2 Ib peeled and deseeded marrow, chopped roughly.
1 1/2 pints stock (I used veggie)
Add the marrow to the cooking onions and squeeze the roasted pulp out of the garlic. I got fed up doing this and ended up just removing the peel and bunging the cloves in whole. Cook for a couple of minutes, then add the liquid. Bring to the boil and cook for about 20-30 minutes, depending how big your lumps of marrow. Remove from heat, liquidize and/or pass thru a seive (optional).
I pepped the soup up a bit with some turmeric and curry powder then swirled some cream through it ~ beautiful.
