I recently decided to make something that required liquid glucose, 140g of it. No problem in general, but for some reason none of my usual suppliers had stock (even tried pharmacies). The closest I found was glucose powder.
Unfortunately, having no clue how to "re-hydrate" the powder to a liquid form, I experimented. :-)
I can safely say that 100g glucose powder was way to much as a substitute for 140g of liquid glucose (which I expected).
However, I was wondering if any of you had a convenient method of turning powdered glucose into the wonderfully thick and sticky liquid glucose, in case I ever find myself in that position.
