when life gives you glycerol ester of wood rosin, make … lemonade?

I’ve never been very impressed or spurred on through a predicament by the saying, “When life gives you lemons, make lemonade.” Any fool can make lemonade out of lemons. If you’ve been given lemons, and all you need is lemonade, things must be working out pretty well.

But what if what you have is some wood?

I was startled recently to read the ingredients on a bottle of Lorina Lemonade.
Lorina makes a carbonated beverage they go as far as to call lemonade, though it contains no lemon juice at all. I searched the label: is it maybe the citric acid? or the ascorbic acid?

Carbonated Water, Sugar, Citric Acid, Arabic Gum (Stabilizer)Ascorbic Acid, Natural Flavor, Glycerol Ester of Wood Rosin (Stabilizer)Turmeric and Riboflavin for Color.

Sure, you can make lemonade out of lemons, but can you make lemonade out of glycerol of wood rosin?
