Easy Orange Marmalade Recipe
Ingredients (makes 3 cups of marmalade)
3 large oranges, or four small ones
2 cups (roughly 1lb) white sugar - the same weight of sugar as the weight of your oranges once they're peeled.
No need to use special jam sugar or setting agent. Oranges have plenty of pectin in them so the marmalade will thicken up nicely even with regular sugar.
Method
Use a peeler to remove a thin layer of zest from the oranges. Slice the zest thinly and put it aside.
Peel the white pith away from the oranges. Remove seeds. Chop the oranges finely and put them in a large bowl along with the zest. A 3L or 3 quart bowl should be big enough.
Measure out the same weight of sugar as your peeled oranges, and add it to the bowl. If you don't have kitchen scales, then just use the same volume (i.e. 1 cup sugar for each cup of chopped oranges).
Microwave on high for 15-20minutes, uncovered, stirring every few minutes. Remember to stir and check on it, or it might boil over. Placing the bowl on a dinner plate will make it easier to put in/out of the microwave when it's hot.
Smear a little bit of marmalade onto a cold plate and check the consistency. If it's not thick enough yet, then microwave it a little longer.
While marmalade is in microwave, prepare some clean jars by pouring boiling water over them to sterilise them.
When marmalade is finished, ladle it into the jars, up to 1/2 inch from the top. Put lids on jars, and turn jars upside-down for 5 minutes to seal and sterilise the lids. Then turn upright and let cool.
