I've come in a bit late on this thread!
Anyway, my sister, years back, would make pineapple gin. It was so exotic to me then, and I thought it must be incredibly difficult to make. In a way it was - getting hold of a fresh pineapple in Lincolnshire in the 1970s was a challenge, but making the gin was simplicity - cut up the fresh, skinned pineapple, put in a kilner/preserving jar, add sugar according to your own taste, then gin, then wait! It was absolutely delicious.
Mmmm - think I'll just pop out for a pineapple and a bottle of gin ...
