Which side to install baroque glass?

I want to put baroque glass instead of plain glass in two cabinet doors in my kitchen.

The baroque glass has two sides that aren’t very different, only slightly:

Only one side has the edge of the swirl sticking out. You can feel the unevenness when you run your hand on the surface of that side.

My question is, which side faces the inside of the cabinet? The groovey side, or the smooth side?
