I've received a request for the cranberry marmalade recipe. The title of this blog post is linked to the original post about the making of it; those photos will give you a good idea of what it should look like, start to finish.
Cranberry marmalade is just a little more refined than cranberry relish, and contains the same sort of ingredients.
The making is straightforward, but you will have to be on hand for most of the cooking; as with most preserves, the high sugar content makes it liable to catch, and when the cranberries first begin to cook, they will foam quite high and need to be stirred down frequently. Make sure the pot/kettle you use has high sides. A 4-1/2 quart dutch oven is just large enough.
2-1/2 lbs. washed and picked-over cranberries (frozen may be used)
2-1/2 lbs. white sugar
1-1/4 c. grapefruit juice
1 lemon; 1 orange; 1/4 grapefruit
Strip the zest, discarding the pith (the bitter white portion of the peel); cut into very thin slivers and set aside. Juice the citrus fruits next; set aside.
Stir water & sugar together until dissolved, over low heat. Add cranberries, juice, and zest.
Simmer until it jells. (This should take about an hour.) The simplest jell test is this: dip a wooden spoon into the mixture and allow the liquids to drop off the long side. When two drops come together into one before falling, the mixture is jelled. Cranberries contain plenty of natural pectin; it's not necessary to add any more.
Pour the mixture into sterilized jars, and cover. When cool, cover with a thin layer of melted paraffin. When that has cooled, add one more. When all wax is solid, replace covers and store in a cool place.
If you prefer to process in a water bath, process for 25 minutes.
Makes approximately ten 8 oz. jars.
