Orange Marmalade

On Wednesday, I made two batches of orange marmalade to give away as Christmas gifts. Mom helped me to keep the "candy" from burning all over the stove and to make sure I canned it all correctly. We started with Alton Brown's recipe, but lacking a good scale and a lemon zester, we had to make a couple of changes.

Orange Marmalade
by Alton Brown, tweaked by Erin Handberg

1 3/4 lbs oranges, 3 large or 4-5 medium
1 lemon
6 c. water
3 lbs + 12 oz sugar

10 (8 oz) canning jars with lids and rings
Canner
8 quart stainless steel pot

Wash the oranges and lemon thoroughly. (I used warm soapy water and scrubbed them with a vegetable brush.) Cut the oranges and lemon with a mandolin, removing seeds as you go. Stack the slices and cut into quarters (I preferred pieces smaller than quarters.) Place the oranges and lemons into an 8-quart stainless steel pot. Set over high heat and bring to a boil. Once boiling, reduce the heat to maintain a rapid simmer and cook, stirring frequently, for 40 minutes or until the fruit is very soft.

Sterilize the jars and rings, canning funnel, ladle and tongs using a boiling water bath or the hot cycle on the dishwasher. Use a small saucepan for sterilizing the lids - they cannot be boiled as long as the other tools or they won't seal.

Place two small plates in the freezer. Increase the heat under the orange mixture until it returns to a full boil. Add the sugar and stir the mixture continually until it reaches 222 F or 223 F on a candy thermometer, and darkens in color, approximately 15 to 20 minutes. You may need to adjust the heat in order to prevent boil over. (This is important - especially if you're using a glass cooktop!) Test the readiness of the marmalade by placing a teaspoon of the mixture on to the chilled plate and allowing it to sit for 30 seconds. Tilt the plate. The mixture should be a soft gel that moves slightly. If the mixture is thin and runs easily, it is not ready. (We ended up heating until about 225 F before the marmalade set on the plate correctly.)

Once marmalade is ready, remove from heat and place next to filling station. Place a canning funnel onto a hot, sterilized jar. Fill with marmalade to just below the threads on the jar (or leave about 1/4" headspace). Repeat until all mixture has been used. Wipe the rims and threads of the jars with a moist towel and top each with a lid. Place a ring on each jar and tighten thoroughly.

Process jars for 10 minutes in a water bath canner.

Our first batch yielded 9 jars and the last batch was an even 10. We got 19 jars of preserves in about 4 hours... not bad for an evening's work!
