China teapot spout - had a clean break. How do I fix it?

I have a china teapot that I'm very fond of. The spout got broken. It's a very clean break, so would glue nicely.

The question - is there a food-grade epoxy I can use? I almost used regular household epoxy, but after reading the ingredients, I thought I should try to find out if there is a product which will hold like epoxy, but not add a little poison to each cup of tea.

Which glue do you recommend?
