just remembered: Soreen malt loaf, black pudding, and recently I really liked haggis
And, I know it's not food, but I do think it's a bit strange-- I'm a big fan of Lemsip when I'm sick (powder sachets containing paracetamol/aka acetaminophen, Phenylephrine HCl, and flavorings to dissolve in boiling water). Today, we got the Blackcurrant flavor for the first time (as opposed to lemon); it's alright, but I'm not fully convinced.
But, speaking of blackcurrant drinks-- I used to drink a lot of "Cider and Black" and Snakebites (lager, cider, blackcurrant cordial). I also like a Soda and Lime sometimes (lime cordial with soda water). I guess these aren't particularly strange, but I'd never heard of blackcurrant before I came here.
