Yes and yes - although I do put in a little cold water first as the instructions say water should be hot but not boiling. My hand blender works wonders either way (I don't use my shaker as a shaker, just as a measure/mixer).When using hot water do you boil it and use straight from kettle and also do you use same amount as if you were making it cold ( 8 flo oz).
Whoa, I never thought of that! Will have to try it (I only have one Tetra a week when I'm at work, but it's a bit rich by itself).I usually have the chocolate tetra hot (half tetra in a mug then top up with hot water).
