Canning is the new knitting. Or is it the new sewing? I can never remember what the correct order of domestic fads is. All I know is that everywhere I look I see people canning.

Ball, the major producer of canning supplies, had record sales in 2009. Even if you don’t know anyone who cans, that should tell you something.

I love seeing this revert back to simplicity. I’m sure many of you will say it is easier to run to the store when you need more jam, but canning is a lot easier than most people think. And seeing a cupboard stacked full of goodies you created yourself has a high level of satisfaction attached to it. It’s the fruits of your labor. Literally.

Not to mention how fantastic this stuff tastes. I love canning because you know exactly what goes into it. Definitely no high fructose corn syrup here.

Just the amount of sugar you want. Spices you want. Combinations you can’t get at the grocery store, at least not for a reasonable price.

In 2009 I made strawberry jam, dill pickles, spicy pickled okra, apple butter, applesauce, spicy pepper jam, pasta sauce, and pomegranate jelly. Is this enough, you ask?

Last month while surfing the myriad food blogs I read, I happened upon tigress’ can jam and instantly signed up. Why not? I already wanted to can more in 2010, probably to the horror of my husband who doesn’t quite understand why we need so many berries or tomatoes.

But considering we’re on our last jar of strawberry freezer jam (granted, I gave away two), I need to remedy the situation in spring, with strawberry, blackberry, and jumbleberry jams.

There will also be lots of salsa, provided I can find a recipe we like. And whatever else the Can Jam will bring, because each month we have a theme to work with. I’m excited.

Even though my January can didn’t go as well as I’d hoped.

January’s theme was citrus, and while I adore clementines, they’re not local (a key part to the Can Jam, as it should be). So I picked out some huge Texas red grapefruit and found a recipe that sounded good. Vanilla Grapefruit Marmalade.

Vanilla grapefruit marmalade is great on ice cream or mixed with honey. Or spread it on buttered toast to wake up your morning!

I had problems getting the marmalade thick enough, and even unsealed the jars and redid them the next day, adding pectin. But it was fun to do, and smelled pretty great as it was cooking.

Added bonus of my hands smelling like vanilla the rest of the day after scraping the beans. (Does anyone have a good method for bean scraping? I always make a mess.) After I had it all done I tasted a little, and I remembered something I had forgotten — I don’t actually like grapefruit.

And I might have done it wrong, or maybe my grapefruit were just stronger, or I cooked it too long, or something … but this was a bit bitter. It makes me sad, but what are you going to do? Learn from it and move on. Maybe it will be great on ice cream or mixed with honey.

Fortunately, a few days later I tasted the marmalade on some buttered toast and it was a lot better. Plus I gave a jar to a grapefruit-lovin’ friend and she raved about it. So I didn’t do anything wrong; it’s just the grapefruit!

Onward to February!

  • 3 large Texas Red grapefruit
  • 3 cups water
  • 4 cups granulated sugar
  • 2 vanilla beans, seeds scraped
  • 1/2 package powdered pectin
  • 2 tablespoons lemon juice


  • Cut the peel from the grapefruit leaving most (but not all) of the white pith on the fruit. Slice the peel into thin strips.
  • Place peel in a pot and cover with water. Bring to a boil. Once it starts to boil, remove from the heat and cover. Let it sit for about 20 minutes. Drain and repeat.
  • Cut off all of the white pith from the fruit. Working over a bowl or a large pot, separate the sections of the fruit, peeling off the membrane and removing the seeds. Squeeze as much juice from the membranes as you can. (Discard all seeds).
  • Add the peel and sectioned fruit (with juice) to a large pot. Add the water and sugar. Bring to a boil and stir to combine. Add pectin and stir until completely dissolved.
  • Lower the heat to a low simmer. Cook until the marmalade is thick and translucent.
  • Add the vanilla bean seeds and simmer another five minutes. Remove from the heat and stir in the lemon juice.
  • Ladle into jars and process in a hot water bath for 10 minutes. Let rest on a dry towel until cool and the lids have popped. Any unpopped jars can be stored in the fridge or re-processed.

  1. OMG the pomegranate jelly sounds amazing…do you still have the recipe for that? I had the same thing happen with my jelly not thickening enough and having to add more pectin. Keep up the good work!!

    1. It was just pomegranate juice, honey, and pectin. There is a recipe for it on the pectin instruction packet. I used the low-sugar pectin since I was using honey. I don’t know if using the regular kind would have helped it be less runny!

  2. Just tried this recipe. Did it take a while for the marmalade to set up after the water bath? It’s been about 24 hours and it’s still kind of runny.


    1. Hi Christina,
      Yes, it did. Jams and such can take up to two weeks to set properly. If you’re worried you can empty all the jars and re-cook the marmalade with added pectin, but based on the recipe I posted it *should* set!

  3. i know this post is pretty old but i figured i would share how i scrape vanilla beans.

    you want to split the bean down the length with a very sharp paring knife. take one half and use the back of the knife and scrape all the seeds out of the hull. i do this 3-4 times to make sure i get as much as possible! repeat with the other half. and after you are done with the empty hulls you can add them to where ever you store your sugar to make vanilla sugar (which is out of this world) or start your own vanilla extract (vodka and vanilla beans)! i never throw away any of the hulls! i have a HUGE container for my sugar since i do so much baking and canning. it seriously holds like 20 lbs of sugar and i keep adding the hulls to that!
