I saw a video online by Jack Mack who created a unique coffee cup and saucer on the lathe by pouring coffee beans and what looked like white glue into a mold. The white liquid looked too thin to be epoxy so I'm guessing it's glue. The brands I have tried all dry either clear or yellowish. Do any of you know of a white glue that actually dries white? I read the comments on his video but he did not answer any of the questions that asked about the glue or epoxy.

White glue that dries WHITE

My initial guess is some kind of resin. Do you have a link to the video?
My knowledge of resin is limited but I thought it looked too thin of a liquid to be resin? Here is the link

That is going to a white resin. I would expect an epoxy would be best for embedding the coffee beans but others may have better experience.

you can make white epoxy or resin by adding pigment to the glue. The same would probably work with PVA.
Epoxy can be thinned, to a water consistency if desired, by heating it.
One caution when heating at least some types of epoxy. It does get quite thin, but if heated epoxy is poured mostly into one shape, such as into a cup, it can experience exothermic runaway and get very hot. When operating a small metallography lab I had some I poured into a mold get smoking hot, turn a burned brown color, and cracked badly. Ruined probably a $500 test. I learned from that!
If the epoxy is dispersed around and through the volume, such as with the coffee beans described by the OP, such a reaction is less likely since the heat might be dispersed.
