I suppose I'm wondering whether fudge with alcohol needs to boil to a higher temp, or for longer, or just needs longer to set or something. ATM - after hours - there is a skin on top but it's quite soft inside, possibly runny, but we haven't taken it out of the tray.
The other stuff wasn't sticky at all, it crumbled beautifully and melted in your mouth (not like modern fudge which is a bit sticky/toffee-ish, iyswim).
DD scraped it off the greaseproof this morning as it still wasn't set, and reboiled it. Got up to temp vv quickly and up to 270 before dd noticed ... Now waiting for it to set again. Will add alcohol a bit later in the process next time.
not sure whiskey works with fudge tbh, but dh wanted it.....
