I boiled canned apricots in a little water and honey in a covered sauce pan (to retain as much flavor/aroma as possible) for 5 min. Let it cool, put it in secondary, gently rack onto it.
I use campden tablets (crushed and dissolved) for fruit additions. Generally, it's one crushed tablet in a couple of cups of water over 3 pounds of fruit, and let sit overnight and then add to the fermenter and rack the wine into it, if it's in secondary.
