2ltrs water 
Cinnamon, fresh rosemary or your choice of additional  flavouring
Method:
Cut the oranges into quarters and squeeze out all the juice through the sieve, into the pan. 
Remove all the pith and insides from the skin, then place this in the square of muslin and add flavourings. Slice the skins into strips – thin or chunky, depending on your preference.
Add the water and sugar to the pan of juice, and bring to the boil. Add the strips of peel to your pan, bring to a simmer and cook until it is 105°C. 
Have a cold plate in your fridge, ready to spoon on a little  marmalade to check it has set.
Pour into jars and hot seal. Pour into jars while still hot, fasten the lids then turn upside down to seal the jars. Leave to cool.
Blood Orange Curd
Ingredients:
315g butter 
250g sugar 
250g egg yolk  (approx. 12 eggs)                                                                         250ml blood orange juice                                                                                         Zest of 2 blood oranges
Method:
Place the blood orange juice, half the butter and half the sugar into a pan, and bring to the boil.
Meanwhile, whisk together the egg yolks and the remaining sugar.  Once the pan has come to the boil, slowly whisk this juice into the egg yolks, then return the mix to the pan. Cook gently,  stirring constantly, until it thickens.
Now stir in the remaining butter and finally, add the zest. Pour into jars, seal and chill in the fridge to set – will take 2hrs.
