If you're not a fan of the bitter flavour in matcha, you have two options. First, make sure that you're not using boiling water in matcha. The ideal water temperature for matcha is 176 degrees Fahrenheit (just before boiling). Lower water temperatures will results in softer, mellower flavour. Higher temperatures will results in a more bitter flavour. If your drink is already bitter, then you can add in other flavours to counteract the bitterness. These include: 1) more of the spices in this recipe (cardamom, ginger, turmeric root); 2) a touch of lemon, lime or orange zest; 3) a natural sweetener like honey.
