Chocolate containing 85% cocoa is usually about 25% sugar so about 12% fructose.

I indulge myself with a few grams of 70% on Friday and Sunday  nights while watching TV. It runs about 35-40%% sugars or up to 20% fructose. Makes you realize how pervasive it is, eh!

i have an interesting recipe from my grandma from when i was little...

1 or 2 eggs separated

mix the yolks with the glucose powder till light colored

add 1 tsp of pure cacao ( not the sweet stuff...)

beat up the egg whites till stiff peeks form and fold into it the chocolate mix,gently.

It is like a chocolate mouse
