Put your chopped onion and rapeseed oil into your machine if you have a saute version, or do the sauteeing on the stove. Lightly fry your onions until soft.
Add the garlic and stock cubes, and finish the saute, by adding carrots and pumpkin. Stir and switch off the saute button.
Add in milk, water and salt/pepper to taste. Ensure the level of ingredients and liquid is below the maximum and above the minimum fill marks.
