Spicy Sweet Potato Soup (Easy)

Sweet Potatoes (Orange-fleshed look best)
Potato (Mashing Variety) - optional
Garlic
1 Vegetarian Stock Cube

To Taste:
Natural Yogurt, Cream, or Soured Cream*
Curry Paste (your preferred type)
Fresh Coriander to garnish

Peel and dice the sweet potatoes and potatoes, roughly chop the garlic. Simmer with the stock cubes, a teaspoon of curry paste and water to cover until the veges are soft. Puree. Add yoghurt or cream to taste. Do not boil after adding yoghurt. Taste it and adjust seasonings if required. If it's too thick (like baby-food) add a little boiling water.

Serve garnished with a drizzle of yoghurt and a generous amount of fresh chopped coriander.

Note: * To make a dairy-free or vegan version, you can skip the cream altogether or use coconut cream, soy or rice-milk.
