Okay, I'm questioning the author cooking skills...
Don't need so much freaking sugar in apricots, there's plenty of fructose in them to pasteurize and make a fine jam. -_-
Apricots are very resilient to weather, thous are available for very long, not very rare...
But, he/she is right about Amaretto, mostly it's made from almonds, but apricot, peaches or cherry seeds verify exist...
