This is the first preserve I made and it was such a success; friends and family loved it and it gave me the confidence to play with the ingredients to make different marmalade for example, change the type of sugar used or add limes instead of lemons or add a blood red grapefruit or add whiskey. Seville oranges come into the shops in January and I usually buy enough oranges to freeze and they last me a year. Oranges contain large amount of pectin so you do not need to use special jam making sugars.
Once you have made the basic marmalade start experimenting with different sugars and add whisky or brandy to give the extra kick.
I haven't made marmalade for years and found this is to be an excellent recipe. There might look to be a lot of peel as you are chopping it up but yes, you do need it all. I shall certainly make this again as my grandchildren loved it.. - 24 Jan 2016 (Review from Allrecipes UK & Ireland)
