Makes approx 6kg – I used 7 small kilner jars when potting up.
Ingredients
2kg (approx 4 lbs) of Seville oranges
4 lemons
4 litres (approx 8 pints) of water
4kg (approx 8 lbs) granulated sugar or preserving sugar
12tsp Scotch whisky (optional)
Method
Put all the fruit into bowl of warm water and give them a gentle scrub to remove any impurities from the skin. Place the fruit into a large saucepan/ preserving pan with a lid and add the water and a lid and simmer for about 1½ -2 hours until the skins are soft and can be effortlessly pierced with a skewer. Remove the fruit from the water and place into a large dish/plate, to cool. Keep the cooking water – you will need this later on.
Place all the sugar in a large roasting tin and place in a low oven to warm through; this helps the sugar to dissolve quicker.
When the fruit is cool enough to handle cut them in half scoop out the pulp and pips and place with any remaining juice and water from the dish back into cooking water. Cut the orange halves very finely into shreds, *I shred about halve the peel to use – its personnel choice how much*.
Bring the pan up to a boil for 15 minutes. Strain out the pulp, pips and put all the liquid back into the pan. Add the warmed sugar and the shredded peel to the pan then heat the mixture slowly, stirring until it has fully dissolved.
Bring to the boil and continue to boil rapidly without stirring for approx 30 minutes. This should take the marmalade to setting point, *see below for setting point*, if not keep boiling.
Leave the marmalade in the hot pan to cool at little it will show signs of the peel suspended in the mixture. Add the whisky if using and stir though.
Carefully ladle the marmalade into warm sterilised jars, seal the finished jars.
*Testing for setting point* - put a small spoonful of marmalade onto a very cold plate – I like to put two plates in the freezer for this. Allow to cool a little and then push it with your finger. The marmalade will wrinkle up when ready - see my post for Lemon & Lime Marmalade this post has pictures showing setting point.
