40 gram (1½ ounces) butter
2 large brown onions (400g), chopped coarsely
3 clove garlic, crushed
1 litre (4 cups) vegetable stock
1.2 kilogram (2½ pounds) cauliflower, cut into florets
250 gram parsnips, peeled, core removed and roughly chopped
2 cup (500ml) water
1 1/4 cup (310ml) pouring cream
2 tablespoon finely chopped fresh flat-leaf parsley
Heat butter in large frying pan; cook onion, stirring, until softened. Add garlic; cook, stirring, until fragrant. Add stock; bring to the boil.
Transfer onion mixture to 4.5-litre (18-cup) slow cooker with cauliflower, parsnip and the water. Cook, covered, on low, 6½ hours.
Blend or process soup, in batches, until smooth. Return to cooker; stir in cream. Cook, covered, on high, about 30 minutes or until soup is hot. Season to taste. Sprinkle with parsley.
It is fine just to use 1 x 300ml carton of cream for this recipe. You will need about 2 small cauliflowers for this recipe.
