What can I do with a large amount of glacé cherries?
If you search for glacé cherries you're going to get nowhere; these are much more commonly referred to as candied cherries and there are plenty of recipes to be found.

More specifically, the most common pairing seems to be almonds. Seems you can make just about any confection from almonds and candied cherries: cookies, nut brittle, bourbon/almond balls, cookies/biscotti, quickbreads, and even fudge.
