Katie, I can't tell you how much
I love Pistachio Fudge! Years ago you could buy it at a little candy shop here but it went out of business. For the longest time, I looked for pistachio extract but it seemed to be only available in huge quantities for professional use. Maybe a year ago I finally found the extract in a little bottle and ordered it from now I can't remember where. Big help, I know.
Anyway, I guess the hunt was more important than the find, and I forgot all about it till now. If I put your recipe in a safe place where I won't forget where I put it, I'll try to remember to make it.
I know the pistachio extract will make it perfect.
