Step 1 Coarsely chop the chiles, onion, cilantro and lemon rind, and place them in a blender. Add the black pepper, garlic, salt, coriander, cumin, Laos powder and turmeric. With the blender running, slowly add the canola oil to make a paste. This makes a generous cup of curry paste, more than is needed for the remainder of the recipe. The paste can be frozen, then thawed as needed to be used in recipes.
