I've been known to go pretty citrus crazy this time of year, but due to our move and some other circumstances I scaled down my usual citrus extravaganza to more of a low-key citrus shindig this time around. Despite my late start to the season, I still managed to get my paws on a lone bergamot that I knew would be the perfect addition to Marisa's grapefruit jam that I had bookmarked last year. If you are a marmalade wimp like me, this jam will be right up your alley. The small amount of bergamot zest adds a bitter, floral note to this preserve which I admit sounds odd, but if you like earl grey tea you know what I am talking about.
Next year I am going to order some real-deal Seville oranges like Tim from Lottie and Doof.

If you can't find bergamot oranges where you live don't let that turn you away from this recipe. This jam is super tasty even without the extra hit of bitter bergamot flavor.
8 grapefruit (approximately 4 pounds)
1 bergamot orange
2 1/2 cups granulated white sugar
1. Wash and dry the fruit and prepare your canning jars.
2. Use a vegetable peeler to remove the peel from the bergamot being careful to avoid the bitter white pith, then slice the peels into very thin strips. Combine the zest strips with about 2 cups of cold water in a medium sized saucepan and bring the mixture to a boil. Cook the zest strips until they are very soft, about 30 minutes then drain and rinse them quickly with cool water. Juice the bergamot and reserve it for later.
3. Supreme the grapefruit by cutting away the tops and bottoms of the fruit, then with a very sharp knife, cut the skin and white pith away from the outside of the fruit and discard it. Over a bowl, carefully cut the wedges of fruit away from the membrane letting the fruit and juices fall into the bowl. Save the membrane and seeds and place them in a cheesecloth bundle. You will use this bundle to add some natural pectin while cooking the marmalade.
4. Add the grapefruit segments, juice, cheesecloth bundle, and prepared bergamot zest and juice into a large, non-reactive pot. Stir in the sugar.
5. Put the pan over high heat and stir until the sugar dissolves and the mixture comes to a rolling boil. Cook the jam, stirring occasionally, until it comes to 220º or passes the wrinkle test. Remove the cheesecloth bundle and ladle the finished jam into prepared jars. Process for 10 minutes in a boiling water bath.
