Coconut milk is one of my favourite ingredients and it makes a fantastic creamy base for all the other robust flavours in this Asian-style soup. Choose firm sweet potatoes with orange flesh for their vibrant colour.
COOK AHEAD
This soup can be made up to 2–3 days in advance and kept covered in the fridge. It can also be frozen for up to 1 month but may need to be blitzed with a hand blender when reheating, as it may split.
WINE
An Alsace Gewürztraminer or German Riesling.

Ingredients
Preparation
Step 1
Preheat the oven to 200°C (400°F/gas mark 6).
Step 2
Place the sweet potatoes in a baking tin, drizzle over 1 tablespoon of the sunflower oil and roast for 20–30 minutes, until tender. Set aside.
Step 3
Heat the remaining 1 tablespoon of oil in a pan over a medium heat. Add the onion, leek, lemon grass, half the chilli and the ginger and sweat for 4 minutes, stirring occasionally. Add the roasted sweet potato with the stock and tomato purée, then bring to the boil. Reduce the heat and simmer for 10 minutes, until the liquid has slightly reduced and all the vegetables are completely tender.
Step 4
Pour the coconut milk into the pan, reserving about 3 tablespoons from the top of the can as a garnish, and cook for another 5 minutes, stirring constantly. Season to taste. Remove the lemon grass and then blend with a hand blender until smooth.
Step 5
To serve, ladle the soup into warmed bowls and swirl in the reserved coconut milk. Add a drizzle of the chilli oil, then sprinkle over the reserved chilli slices and micro coriander.
