For the coconut cups I made, I just sealed them with canning parafin. You can get that stuff at most grocery stores. AND it's sure to be food-safe. Then buffed the hell out of them to remove the excess wax.

I don't know how such items would be professionally finished.

(Of course, I epoxied the cup to the base, so what do I know. Looks like something the Professor made.)
