Cover the apples in cold water and bring to the boil, gently cook for 30 mins until the apples are soft and mushy.
I have a jelly bag which is basically just muslin with handles, put the pulp into the bag hang it over the pan and let it drip into a saucepan over night. Never stir it or it will make the jelly cloudy.
Bring to a rolling boil, the recipe I found suggested 30-40mins of boiling but I felt this might be too long. Keep an eye on it as it can set quite quickly as there is loads of pectin in apples, which creates the set.
Chill two plates in your freezer to test for setting if you do not have a thermometer. To test put a spoonful of jelly on to the cold plate, after a minute or so touch the jelly and if it has set it will wrinkle. Turn off the heat and pour into steralised jars.Your done!! I love the colour its a really lovely pinkish red:)
