Jamming…strawberries

Last month I bought some Hood strawberries, local berries that are so delicate they don’t go for sale outside the area. They’re tender and sweet and perfect. We ate some, and I made a small batch of strawberry balsamic jam with the rest.

Three little jars of heaven. I liked Marisa’s recipe at Food in Jars, but I prefer my strawberry jam less cooked, so that there are still chunks of berries and a lighter color and less cooked flavor. This recipe uses no added pectin, so you have to cook it longer for it to set as jam. Still, delicious.

This week California berries are on sale at the supermarket for 99 cents/pound, so I decided to have another go at it. I bought 3 one pound boxes of berries, and used them all. A bit more than planned, but I don’t really like fresh strawberries, so there was no use in keeping some back!

I decided to use Pomona’s Pectin, which works with less sugar and the cooking time is minimal. You might remember my plum jam adventures from last year with Pomona’s Pectin. Ultimately, I decided that plum jam really wants to be made with traditional pectin and more sugar for that jewel-like set, so I’ll be back to that this summer. But for strawberries? Perfect.

I like the fresher taste and bits of fruit in this version with less cooking time. The only thing that I didn’t love is that my fruit wants to float in the jam after processing. Marisa says that it’s due to air trapped in the fruit, making it lighter than the rest of the jam. Possible fixes: Cut the fruit smaller (I wanted chunks, so no), macerate fruit with sugar overnight (too late for this time), or swirl fruit in jars as they cool (bingo).

I guess I missed one of the jars! I’ll keep that one for me, and mix it up when I open it. I have 4 half pints and 6 4-ounce jars.

The instructions for Pomona’s Pectin say to mix the pectin with the sugar, I think so it doesn’t clump. Next time, I’ll keep back half the sugar to mix with the pectin, and use the other half to macerate the berries overnight. Problem solved.

Notes to self for next year’s strawberry, with or without balsamic:

Strawberry balsamic jam

6 cups mashed berries, a little less than 3 pounds (I gave them a quick whirl in the food processor)
3 cups sugar (I might cut it back to 2.5 next time)
3 tsp Pomona’s Pectin
3 tsp calcium water
2 TBS balsamic vinegar, or more to taste

Combine fruit and 2 cups sugar; macerate in refrigerator overnight.

Canning day: Combine pectin with remaining sugar; set aside.
Add calcium water to fruit. Bring to boil. Add remaining sugar and pectin. Return to boil, stirring to dissolve pectin. Remove from heat.

Fill jars to 1/4″ from top, wipe rims clean, screw on lids. Process 10 minutes in boiling water bath canner. (Sea level, your altitude may vary! See instructions in the Pomona’s Pectin packet.)

Yield: 8-9 cups

If fruit still wants to float, swirl in jar after cooling 30 minutes. Any sooner and it’s still too liquid to keep it from floating back up.

What else? I noticed that a vine has taken over our dead bamboo stand. I thought it might be morning glory, which would need to be removed. It’s been growing on the bamboo for a couple years, wispy and delicate. But this year it’s very vigorous, and covered with buds, which don’t look like like morning glory.

Yesterday it came into bloom. It’s too high for me to see from the ground, so I took this picture through the window.

It’s a passionflower (passiflora) vine! I think it was a volunteer from the neighbor’s yard. Pretty, but I can see how it might get out of hand. In fact, it is jumping over to the lilac on the left, so I pulled some down.

Should I let it run free, as long as it leaves my lilac alone? The lilac needs pruning, so that will leave space between. But this thing is WILD! I read that some varieties make fruit, and so I guess I’ll wait it out. Passionfruit jam?

Are you jamming this season? I’m looking forward to plums. This year it’s going to be plum bourbon jam…

  1. Passion flowers are so pretty, but keeping control of the vines? Oh MY! The jam looks so GOOD!!! I see toast in your future.

    Yum! I’ve always wanted to try jam/canning.

  3. I haven’t made jam in years!! Inspired to make some this year!

  5. You should definitely wait it out to see if it bears fruit. Fresh off the vine passionfruit(lilikoi in Hawaiian) is so incredibly delicious!! I grew up eating them off the vine with a tiny bit of powdered sugar sprinkled on it. Yum!
