I am making a white chocolate fondant recipe. The recipe calls for 5 oz. of glucose. Is this 5 oz. liquid or 5 oz. in weight?

Also, I purchased the Wilton glucose and it is difficult
to work with. Is light corn syrup a good substitution for the glucose?

Thank you so much, Brooke

Light corn syrup isn't exactly the same, the kind of sugar is slightly different, but it works just as well in fondant and most other recipes. I never buy the glucose because it's just way more expensive than the corn syrup.

As far as measuring goes, the measurement should be the same whether it's by volume or by weight, just seems like weight would be easier to do. You can spray your measuring cup with non-stick spray before putting the syrup in and it will come out much easier.

According to Rose Levy Beranbaum in "The Cake Bible,"
"Since the major difference between glucose and corn syrup is the
water content, if some of the water in the corn syrup is e evaporated,
it can be used interchangeably with glucose."

To do that, her "recipe" is:
"Bring 1 cup light corn syrup to a full boil and remove from heat
Cool completely and stir in 1/2 cup unheated corn syrup."

Hope that helps.

The reason for glucose is that unlike corn syrup glucose will not recrystallize it is an invert sugar.Corn syrup is a type of invert sugar but it will recrystallize.

Thank you so much for all of your replies. I am glad to hear I don't have to keep buying glucose. It is expensive and I want to make a few recipes that call for it.

I am making a white chocolate fondant and went ahead and measured in 5 liquid oz. of glucose. It has to sit 24 hours but seems to be a good consistency this morning. My confusion was because the Wilton Glucose was listed as a 12 oz container. When I measured out 5 oz in a liquid measure there was less than half left in the container and it didn't seem to make sense. Why package it by weight if it is a liquid?

I'll have to do more research on the invert sugar/crystalizing thing; that doesn't sound good. The science behind all of this is lost on me at this point but I am a beginner so hopefully will learn.

Thanks again for the help!!
