Four Fruit Marmalade(makes about 4 small jars)

Ingredients:

1 large lemon
2 large limes
2 medium thin-skinned oranges
3 clementines
4 cups water
1/4 tsp. baking soda
5 1/2 cups sugar

Preparation:

Wash all fruits thoroughly. Slice off the stem-end of each fruit, far enough to reveal the flesh.

Using a mandolin or hand slicer, slice each fruit as thinly as possible, until you get to the point where there’s more pith & rind than flesh. Do this over a bowl (like a flat soup bowl) to catch the fruit and juices. Take care to remove seeds as they appear. If you get any large slices, take a knife and quarter them. You should wind up with about 5 cups of fruit.

Place the shaved fruit in a large saucepan along with the water, bring to a boil, and boil rapidly for 20 minutes, stirring occasionally.

Add the baking soda, lower heat and boil gently for another 20 minutes, stirring occasionally. The baking soda will make the contents foam up rather suddenly, so don’t be alarmed.

Add the sugar, mix well, and raise the heat. Boil rapidly, stirring occasionally, for about 30 minutes, or until the mixture passes the “gel test.” (See notes, below)

Ladle into sterilised jars and process (boiling water canning method) for 5 minutes.
