Love the taste of my protein shakes, I look forward to having them daily, so if yours do not taste decent I think you are buying the wrong whey.
For a great recipe that tastes as good if not better than a Gloria Jeans Iced chocolate or similar combine 200ml of milk, about 10 ice cubes, 40gram of WPI, I use BN Chocolate or Vanilla and blend till it is a nice consistency.
It's ice cold, delicious and good for you, plus it fills me up, much better than ice cream.
PS I don't add carbs to my shakes as they already have enough calories for my liking.
