I found a spiced courgette chutney recipe and followed the basics, but doubled it up as the marrow was so large, and added a couple of extras.
4 onions, chopped
600g Tomatoes, chopped
1100g Marrow, chopped (spongy flesh in middle removed)
600ml Sarsons pickling vinegar
2 large Granny Smiths apples
500g light Muscovado sugar
1 tbps Mixed Spice
1" piece of fresh ginger, grated
4 garlic cloves, finely chopped
2 green chillies, finely chopped
3 tbsp dark Rum
3 cinnamon sticks
I never followed the last step (leaving 2-3 weeks before eating) and ate some immediately with cheese spread on a crumpet.
Chutney makes a great Christmas present, along with some nice cheese, crackers and a bottle of Port or wine, wrapped in a gift basket.
If you want to make it look really special you can use hinged jars, available from craft or kitchen stores. Or you can use jam jars and tart them up a bit with a piece of fabric and a label. I used a circle of hessian secured with ribbon and a small wooden star (my handwriting leaves a lot to be desired!) - both purchased from Ebay.
