I used grapefruit, oranges, blood oranges and meyer lemons.
It is dee-licious.
You should make some.
Four Fruit Marmalade
www.rurification.com
2 grapefruit, sectioned. Zest one of them.
2 oranges, zested and sectioned.
2 blood oranges, zested and sectioned.
4 meyer lemons, zested and sectioned.
7 cups of sugar
1/2 tsp salt [to cut the bitter]
Do your zesting first. Put the zest in a pot with 3 cups of water, bring it to a boil and let it boil happily until you have all the sectioning done.
I use a serrated grapefruit spoon for the sectioning. Just cut the fruit in half and go at it. Pull the seeds out as you find them.

Put all the fruit stuff and the zest stuff in a good pot with a wide bottom. Add the sugar and salt. Bring it all to a boil. There's no pectin in this recipe, so you're going to have to boil it down until the gelling point - 220 degrees here in Indiana. Check my Jam page [tab above] for the gelling points at higher altitudes.
Let it boil hard. Mine boiled until the foam started creeping up the sides of the pan. That's normal. You might stir it once in a while to make sure it's not sticking.
When you reach the gelling temp, turn off the heat, ladle into jars, put the lids on and process 10 minutes for canning. [See my Jam page, tab above, for more information on processing for canning.]

I made a little extra of this marmalade because, guess what!
Under Indiana law, I am allowed to sell my jam now as a Home Based Vendor. This means I have to label things with a specific disclaimer and I have to do pH testing of every batch, but that's not a problem.
How do you like the front side of my labels?
