Mango Purée is made by pureeing the mango with a blender to make a smooth mixture. To turn the puree into a coulis, you pass it through a sieve to remove all the extra pieces of pulp and fibres. Coulis is like a smooth sauce that you might be served with a dessert, whereas puree may be used in smoothies, cocktails and desserts as an ingredient. In this recipe, we take the extra step of straining the mango puree as we also put the mango coulis inside and on top of the cupcake and it's more enjoyable to eat if the coulis is nice and smooth.
