I have omitted the word "hidden" from the whippet group, which would *technically* have saved me from one word being interchangeable. If you didn't spot it anyway, great- if you did, please pretend that I did write "hidden" and enjoy the fact that one word could fit in all four groups! Sorry about that :)

Yes I was about to mention Cream! Maybe a finger of whisky too?
Or maybe I’m making excuses cos you beat me hands down with this one :)

Devious! 😀

Trust you to spot it CM4PM! I'm ok with whisky as I don't think there's a food called whisky finger- but I think I'll invent some! Maybe a cross between cranachan and a cream finger? (drool). Wish I'd just put hidden, then I'd get away with it. Hey hoo :)
