Tart, sweet flavoured rhubarb usually appears in January. Another field-grown variety also appears in April and is less tender but often more flavourful. It's a good source of vitamin C and studies have also linked the fibre from rhubarb with reduced cholesterol levels. Cardamon has a warm, spicy-sweet flavour which complements the rhubarb well.
450g rhubarb, coarsely chopped
Preheat the oven to 190c/Gas mark 5.
Mix the rhubarb, honey and orange juice and zest together. Place in an ovenproof dish and cook in the oven for 30-45 minutes, until the rhubarb is completely soft. Remove from the oven and leave to cool completely.
Take out the cardamom pods and puree the fruit. Fold the greek yoghurt into the puree, creating a pretty ripple effect. The taste test: If it is not quite sweet enough, you could add a little more runny honey or maple syrup at this stage.
