Place everything in a saucepan and simmer gently for 20 minutes.
Whizz everything until smooth.
Notes
You can leave out the red lentils, or add any other cooked bean. Leave them whole, whizz them up or do half and half. The curry can be anything at all. So a tblsp of any curry paste, say Balti, Rogan Josh or Jalfrezi, or any curry powder mix. Or you could use any separate powders. If I was doing that, I would use a tsp each of coriander, cumin and turmeric, and a bit of chilli from the greenhouse.I am using up apples in absolutely everything at the moment, so I added 4 tiny ones, just quartered and cored, not peeled – too small!You could leave out the coconut and add more water, or use half a tin.Some leftover roasted vegetables would be lovely in this.
