The story goes that the Seville orange marmalade was invented in the early 18C, when a Spanish ship with a cargo of Seville oranges found refuge in Dundee. The oranges were snapped for pennies by the local merchant James Keiller, and his wife turned them into a novelty preserve.
There are many recipe for Seville orange marmalade online, the one that I used as my source of reference is the ultimate Seville orange marmalade by BBC Good Food. I have adapted it and used a mix of Seville and blood oranges, plus added some whisky.
Seville & Blood Orange Marmalade
800g Seville oranges
500g blood oranges
1 lemon (juice)
1kg preserving sugar
1.6kg granulated sugar
Take a cooking pan big enough to take in all the oranges, pour about 2 litres of water to cover the fruit as well as the lemon juice. Bring to boil, then lower the heat and simmer on low for 2 hours. At this point the peel will be easily pierced with a knife or fork. Once cooled to tepid, take the oranges out and let them drip via a colander over the pan to get all the juices.
Cut the oranges in half. Scoop the insides, pips and all (that gives a high pectin content to your preserve), add them to the pan with the water where the oranges were cooked. Bring the liquid to boil and cook for about 10 minutes. Then strain the liquid through a sieve, and using a wooden spoon, squash the orange bits through. Discard the remaining pips and pith.
Cut the peel with a sharp knife into strips of your preferable thickness, fine or wide. Add the sugar, both granulated and preserving to the pan of orange liquid and bring to boil, until all the sugar is dissolved. Add the shredded peel. Bring to boil again and bubble rapidly for 20-25 minutes until the setting point is reached.
Add the whisky if using. You might want to add a little blob of butter to get rid of the scum, stir it in gently. Let the marmalade cool a little (maybe 10 minutes), then pour it with a ladle into sterilised jam jars. Seal them while still hot.
If you don't have blood oranges, just use the Seville oranges, but the combination of two types of oranges makes it more exciting and the colour is beautiful.
Chris from Cooking Around the World has invited the bloggers to submit a recipe which represents Great Britain, and though I'm fashionably late, this is my entry for this linky.
