Does anyone have a ratio chart on over-the-counter liquid thickeners for nectar and honey thickness?

Liquid thickeners should all have a web site. I would go there. Geaton is right. We have to keep ourselves internet savvy to survive.

In my experience it's a lot like cooking - use your preferred product and once you understand the basics you can wing it a little, remembering that too thick is always better than too thin, and since these products are fast acting adding a little extra is no big deal.

Instructions vary according to product.
Look product up online.
Experiment with product in home.

I used the product Thick It for my late husband and the ratio was right on the container for the consistency you need/want.
It's not complicated.
