For plain milk, omit the cocoa powder, extracts and sweetener. Don't omit the salt, that little bit makes a big difference in the flavor! Toasting the hazelnuts for 8-10 minutes in a 300F oven will help improve the hazelnut flavor of the milk, but it's good even without the toasting. If you're using almonds, there is no need to toast them first. If your tap water doesn't taste good (mine doesn't), be sure to use bottled water for this recipe.
