How to make Marmalade.
I used 5 large oranges for this recipe. First, take all the peel off the orange by cutting the top and bottom of the fruit, and slicing off the skin. Place the fruit in a food processor and blitz for a few minutes to make the juice.
To prepare the orange peel, you want to cut as much of the pith as possible. Pith is the white part of the skin, which is very bitter in flavour and will give the marmalade a bitter aftertaste. Using a sharp knife, cut the pith off. Once the peel is pith-free, (well, as much as you can!) julienne the peel (cut into thin strips). To remove the last bit of bitterness, I boiled the chopped peel in water three times, changing water in between each stage. After the third boil, strain from the water and place in a large pan.
Going back to the blitzed orange, pass through a sieve and pour the juice into the large pan. I added one vanilla pod and a thumb-sized piece of ginger- however these ingredients are optional. Top up the juice with 1.6L water and bring to a gentle boil and leave to reduce by half.
Once the liquid has reduced by half, add 1kg caster sugar and reduce the heat. Leave to boil for a further 15 minutes and pour into sterilised jars, sealing it with the lid immediately.
