Prepare the ingredients for the shake.
Add the flaxseed meal to the milk, then add the banana, yogurt, and extract and bitters.
Blend and finally add the balance of ingredients. Blend until smooth. Sweeten to your liking. I prefer to sweeten with honey. You may add ice to the shake if you want it colder. Generally, the banana, if frozen enough, will get the shake cold enough to drink at once.
