YIELD: 1 pint 

Use the most flavorful tangerines you can find.

Do not double the recipe, the microwave will not like it and you will end up with a giant mess.

Use a high-sided microwaveable container as the jam bubbles up like a 2-quart glass mixer bowl, from which you can pour directly into the jars.

After you get the basic technique down feel free to play a bit adding a touch of booze or spices.

INGREDIENTS:

¾ lb tangerines, (Satsuma, Clementine or Dancy)

1 ¼ cup sugar

1-tablespoon rum (optional)

½ teaspoon freshly grated nutmeg (optional)

METHOD:

Start your hot water bath and prepare your jars and lids.

Peel and seed tangerines (or get seedless) removing and discarding all the white stringy bits from the outside and down the center of the fruit.

Place peel, pulp and sugar in the bowl of a food processor. Puree, making sure that all the peel and section skins are reduced to a pulp. It will be quite liquidly.

Pour into a high-sided microwaveable bowl adding rum and nutmeg. Cover tightly with saran wrap that you have pierced a few times to vent.

Microwave on high for 5 minutes. Stir; remove saran wrap and return to microwave for 7 minutes. Remove, stir and check thickness. At this point, depending on the juiciness of your fruit you may want to return it to the microwave for another 2-3 minutes. It continues thickening as it cools.

Stir again and pour or ladle marmalade into your prepared jars, leaving 1/2-inch headroom and removing any air bubbles. Wipe rims and place lids on screwing on lightly.

Place jars in canner making sure the jars are submerged. Return to a boil and process 5 minutes (timed from the boil) for 4oz jars and 10 minutes for 8oz jars. Remove canner lid and wait 5 minutes before carefully removing jars. Place jars on towels or a cutting board to cool. Label and enjoy.

Am thinking that this method should work for any citrus fruit to make marmalade.  If there was a LOT of thick walled peel, I'd probably scrape a bunch of the pith away first, though.

Also, I ran into this recipe yesterday somewhere.  Got interrupted and will post the source when I remember what it was!
