I made this last night and am eating the first bowl for lunch - and it wins the prize for best soup I have EVER made! I think a touch of chilli wouldn't go amiss though...
Beetroot, lime and coconut soup – for 2-3
6 medium-sized beetroot (about 400g)
1 tablespoon of olive oil
1 small onion, thinly sliced
1 stalk of lemongrass, white part only, thinly sliced
2 kaffir lime leaves, spines discarded and thinly sliced
¼ of a dried lime, seeds discarded OPTIONAL, OF COURSE
250ml of vegetable stock or water
1 small tin (about 200ml or less) of coconut milk
Sea salt and pepper
Juice and zest of 1 lime
Tamari to taste
Thick, plain yoghurt
Chives, snipped into short lengths, to serve
Preheat the oven to 200 C (400 F). Lightly scrub the beetroots and trim all but 2 cm (1 inch) of the stalks. Wrap them, unpeeled and whiskery tails in tact, in a decent-sized sheet of baking paper, then wrap this parcel tightly with aluminium foil. Bake in the oven for 1 ½ hours, or until tender all the way through. This can be done hours, even days ahead.
When cool enough to handle, trim and discard the stalks and tails, then peel – the skins should come away easily when rubbed with your thumb. Cut into large chunks and set aside.
Heat the oil in a saucepan. Add the onion, lemongrass, lime leaves and crumble in the dried lime. Cook over a low heat until softened, about 5 minutes. Add the beetroot chunks and the stock. Bring to the boil, then lower the heat and simmer for 20 minutes.
Whiz in a blender. Add the coconut milk and puree until smooth. Rinse out the saucepan, return the pureed soup to it and gently reheat. Taste for salt and pepper. Add a little tamari to taste for a deeper flavour and squeeze in the lime juice. Serve with a spoonful of yoghurt and sprinkle the lime zest and chives over the top.
