Cut a small onion in thin pieces and then roast it with butter. When it is golden brown add the flesh of a yellow pumpkin, which you cut before in pieces of 20 millimetres. Then roast it for 1 minute. Give water to the soup and cook it for 10 minutes. Then take the mixer and mix everything. Add the spices - I prefer salt, pepper, a little bit chilli currypowder, 3 tbl spoons vinegar and 5 tbl spoons of pumpkin seed oil. Mix everything a second time and serve it.
For decoration add some pumpkin seeds.
