2 Start curry
Heat a non-stick pan over a medium heat with a drizzle of oil. Once hot, add the onion with a pinch of salt and fry for 5-7 min until softened. Once softened, add the garlic, red curry paste (spicy!) and ginger and fry for 1 min further. Add the sweet potatoes, measured water, soy sauce, peanut butter, coconut milk, coconut sugar and lime leaves and simmer (don't boil) for 15-18 min, covered, or until the potatoes are tender.
