Right, if you have caffeine sensitivity, are pregnant or on any medication that is not suitable for use with caffeine I would advise against drinking one of these.
This makes about 1L (one litre) of finished coffee. It is strong and will give you more than a perk. It contains about 200mg caffeine which is a fifth of a lethal dose you have been warned.
Step 1: Getting the Equiptment...
A smoothie maker is best but a blender would work as well.
A jug or bottle for the finished product.
Sugar or sweetener to taste.
About one litre of milk.
About 10 teaspoons of instant coffee granules.
First things first, measure out the coffee. I use 10 teaspoons, add more or less if you wish. Then add the sugar or sweetener to taste.
Step 2: Making It Smooth.
Step 3: Add Milk
That will ensure a smoother, more even mix.
