I'm locked in the quote mode to reply on my phone, but this is my two cents:
I did the american amber ale recipe in there and let it finish on top of 3 pounds of apricot puree. I liked how they went together. I like in that book the way they talk about creating recipes and how you want the flavors to meld, yet represent their individual qualities. I was going for the amber as a breast, biscuity, malt forward crust like element in an apricot tart. The apricot preserves took a while to meld and make one beer, but now that it has been in the bottle for a couple months, it is very nice. Pectin enzyme may be helpful for a clearer beer, if that is important to you. I found mine to be slightly cloudy, and it is something I would address is I was to rebrew it. I can see the peach playing well with some stone fruit notes in certain varieties of hops. Amarillo may be worth considering for that. Have fun!
