Empty the marmalade into a large jar and pour the gin over it.
Stir until blended, cover and set to one side for around two weeks. Stir or shake occasionally - this will help the gin infuse.
Place a sieve over a large jug and pour the contents of the jar through the sieve - save the marmalade peel!
Either return the marmalade gin to the original bottle or decant into smaller bottles to store. If you want to make a really bespoke present, keep your eye out for vintage glass bottles you could use to pour the gin into. And a homemade label is a must!
TOP TIP: Line a tray with non-stick baking parchment. Blot the drained peel with kitchen paper and distribute evenly over the tray
Melt 2 bars plain chocolate in a small bowl either in the microwave or over a pan of hot water then pour over the orange peel pieces. Leave to set and then break into large shards. Can be stored in a sealed jar. Serve the marmalade gin in small glasses to sip while nibbling the dark, orange chocolate bark.
