Why is glucose not used in many cake recipes? Glucose is used in some recipes to make a cake soft and fluffy (for example, this Strawberry Shortcake recipe video https://www.youtube.com/watch?v=Wc6F_dLJo8o).

What is the reason glucose is not widely used in other cake recipes?
Glucose is very expensive, unlike caster sugar (sucrose, also commonly called "table sugar") which does the job, and is much easier to work with. Glucose in the modern kitchen is only really used in meringues.
