To add to the taste-bud deceptions ... I learned a long time ago that Bitter-Almond Extract was made from peach pits. .... After reading your post, I went to Google University to find out ....
Of course, I found a decent answer on a sewing website??? here
and a video --
So ... you apparently can make almond extract from most of the fruits that have stones - but you always need to be careful that you release the cyanide. To avoid the cyanide ... just use almonds. Now, I might have to make some.
Thanks for your post - it took inspired me to dig a little deeper!!
