A chance thought as I was enjoying a glass of gin and tonic led me to ponder the possibility of using other kinds of citrus fruit, limes in particular.
Which resulted in me making 2 small batches of lime marmalade, one lime with Gin and Tonic, and the other Mojito - lime with fresh mint and rum.
I think they worked out reasonably well.
I may also use some in baking - chocolate and orange cupcakes,perhaps. . .
