Just thought this might be of interest to folks.
Just measured then weighed the following several times, then took the average. Measured with a proper measuring spoon and weighed with decent digital scales. Been meaning to do this for a few weeks now, I'd assumed they'd be the same. Maybe someone else can have a go weighing either of these sugars and see if they get the same results.
Glucose powder
40 x level teaspoons = 81.5g
Granulated sugar
40 x level teaspoons = 132g
I've no idea if it's the weight or volume which is the sweetness equivalent.
If it was only 10g or so different I wouldn't have bothered bringing this up, but over 50g is worth mentioning I feel.
Differences in volume/weight of glucose & sugar.
