Re: sugar

Your point is well taken. I can certainly understand how the previous
messages could be confusing.

For the record, however, I relate the percentage or quantity of any
specific ingredient to the amount of pigmented gelatin liquid
solution. Thus, in noting that I use about 1-3% sugar I mean that I
use about 2.3g of sugar per 100ml of liquid gelatin solution. This is
consistent with the way I discuss the concentration of the gelatin in
the solution - for example, a 10% pigmented gelatin solution consists
of 10g of gelatin in 100ml of water.
