Wash the oranges and lemon. Slice them coarsely. If you like peel in the marmalade, slice one of the oranges very thinly and cut into ½-inch pieces and set aside.
Place the remaining fruit in a food processor and process until the peel in is tiny pieces.
Put the fruit in a medium saucepan, and add the slices set aside. Add honey and whisky and water. Bring to a full rolling boil stirring frequently. Keep at a full, rolling boil until mixture resembles a thick syrup, maybe 2 hours.
Remove pan from heat, and allow to cool 30 minutes.
Slowly add gelatin stirring constantly to avoid clumping
Then pour into a jar or storage container.
Notes
Any leftovers can be refrigerated for 3 days, or freeze them for several months. This is so delicious it won’t last long. You can also can this marmalade for longer-term storage if you have the time and equipment.
