Spring has sprung and not only are the birds and bees stirring, but humans on the Central Coast are out and about after a much-needed rainy winter season.
There are parties, garden workdays and spring cleaning to attend to. All of these activities leave very little time for working in the kitchen! When my rhubarb started coming in, I decided I wanted to use the fresh stalks without spending too much time in the kitchen. So, I made strawberry rhubarb jam with low-sugar pectin. (Ball Realfruit Low or No-Sugar Needed Pectin)
Friends and family often ask for a lower sugar product so no-sugar/low-sugar pectin is a great solution to use with a berry jam recipe. The peel-off label on the jar of pectin provides a useful table of ingredients listing the amounts to multiply by the number of jars you wish to make. My water bath canner fits about 7 jars, so I multiply the recipe by four to make about 8 - 8oz. jars of jam. That eighth jar is always my sampler that I do not process and just store in the fridge.
Strawberries can often be found at the farmers markets on the Central Coast, sometimes year-round! These were purchased at Cal Poly while I was in the orchard u-picking citrus fruit.
I grew up with rhubarb growing in our garden in Michigan. My Finnish grandmother always had a patch in her garden, too. It is not always easy to find here on the Central Coast, so I decided to plant my own. These stalks came from my second plant which did much better planted in full sun.
The people of China were the first to use this plant as a medicinal herb over 5,000 years ago. When the English discovered rhubarb, they began eating the leaves which caused great stomach discomfort as the leaves contain oxalic acid and should never be eaten. Two hundred years later, Europeans discovered the tart stalks and used them to make tarts, which gave rise to the nickname “pie plant.”

Now let's get started. First, follow this link to read up on how to properly prepare your jars.
Once your jars are preparred, clean and remove any blemishes and stems. Chop your strawberries, arranging them in a single layer. I use an old-fashioned biscuit cutter for chopping the berries. I leave it a little chunky as I like pieces of fruit in my jam.
Then, measure the chopped strawberries.
Chop the rhubarb into equal sized pieces.
Then, mix the chopped and measured fruit into heavy bottom pan and add water or fruit juice.
Gradually stir in pectin and bring to a full rolling boil, stirring constantly.
Then add sugar. It is important to fully dissolve the pectin before adding the sugar.
Return to a full rolling boil and boil hard for 1 minutes, stirring constantly. Remove from heat and skim any foam off the top that has formed.
Pack jam into prepared 8 ounce jars and measure the head space. There should be ¼ inch from the jam to the top of jar.
De-bubble each jar by sliding the tool down the sides of each jar.
Process the jars for 10 minutes in a boiling water bath canner at a full rolling boil. Steam will escape through the side of the lid during this process. At any point, if the water drops below the boiling point, start your timer over for the full processing time as directed by the recipe. After 10 minutes, turn off the heat, remove the lid and let the jars stand for 5 minutes.
After the 10 minute processing time and 5 minute standing time, carefully remove the lid and let the steam escape away from you. Leave the jars in the water bath canner for another 5 minutes.
When removing the jars, be careful not to tip the jars. Leave any remaining water collected on the lid in place. Water spots will likely form on the lid, which is ok. A little vinegar on a clean towel will easily remove those water stains.
Remember to label and date the jar and remove the band for storage. Store for a max of one year.
This recipe is a quick process and perfect for a teacher gift or host gift for spring parties, or to include with your beach picnic in the summertime!

It's that time of year again! The dominant variety of apricots, Blenheim, that have a short season here on the Central Coast, have arrived. I used to have a Royal apricot tree in my yard and made delicious jam every year. Unfortunately, it contracted a fungal disease and slowly lost its limbs one by one which ended my annual tradition of making jam.
Last year, I wanted to bring this jam making tradition back so now I purchase my Blenheim apricots from my local farmer's market. The farmers there have been growing apricots for years and they have some of the tastiest ones around.
First, gather your ingredients and canning supplies. This recipe makes about nine 8-ounce jars and you will need 8 cups chopped and pitted apricots, 4 tablespoons of lemon juice, and 6 cups granulated sugar. Make sure your cooking space is clean and wash your hands.
I decided on a simple no-pectin recipe from the Ball Complete Book of Home Preserving (2006) so the pure delicious flavor of the apricots could shine through.
I like to listen to music while I jam, mostly bluegrass, but any music will enhance your experience and help pass the long minutes of stirring the pot when you choose the long boil, no pectin method.
I washed and dried and chopped the apricots, removing any blemishes and getting rid of any damaged pieces. You want a mix of about ¾ ripe to ¼ under-ripe apricots since the latter contain more natural pectin to help the jam set. Prepare fruit in small batches, just enough for one recipe for best results. For my second batch, I chopped the apricots in smaller pieces and ended up with more fruit in my recipe.
In a large saucepan, combine the sugar, lemon juice and the apricots. I let this mixture sit for about a half hour as the fruit begins to release its juices and starts to form a syrup. This helps prevent sticking as you heat the mixture over medium heat.
Add 6 cups of granulated sugar.
Add 4 Tablespoons of lemon juice. The juice needs to be from a bottle purchased at the store. This is a guarantee that the juice will have the right pH, at least 4.5 percent acidity whereas freshly picked lemons can vary in their pH.
Add the 8 cups of chopped apricots. Although the recipe calls for peeling the apricots, I leave the skins on and end up with a smooth jam.
Stir the pot occasionally to help the sugar dissolve and keep the mixture from sticking. Once the mixture has broken down and begins to thicken you need to stir constantly as it boils. This is where your favorite music or a good podcast comes into play.
I decided to use the temperature test since it is the most accurate way to see if the gel stage of the jam has been reached (Ball Book, 2006, pg. 21). After cooking for an hour, the jam reached only 210 degrees, so I decided to try the sheet test with a spoon that had been in the freezer for several minutes. The jam came off the spoon in sheets, so I decided to ladle into the hot jars. The second batch of jam did reach 220 degrees after only about 45 minutes as I boiled this one a little harder. Interestingly, the first batch which was cooked longer turned a darker shade of orange while the second batch was brighter.
Spoon or sheet test: Dip a cool metal spoon into the boiling jam. Lift the spoon up and out of the steam so it starts to fall off the spoon. If the jam forms light and syrupy drips, keep boiling. If the jam comes off in one sheet, the jam is ready to place into hot jars.
Ladle the hot jam into half-pint jars leaving a ¼ inch headspace. Use a debubbler or chopstick to release any air bubbles that may have formed.
This jam is very sticky so make sure the rim is wiped clean with a damp paper towel before placing the lid on the jar.
Place the lids on the rims and screw on the bands just until fingertip tight.
Set filled jars onto a canning rack and submerge into a water bath canner with 2-3 inches of water covering the tops of the jars. Bring to a full rolling boil and process for 10 minutes. After 10 minutes, turn off heat, remove the lid and let the jars stand in the canner for 5 minutes before removing the jars to a clean towel on your counter. Be sure not to tip the jars as you are removing them as the mixture could bubble under the lid and cause the lids not to seal properly.
Let the jars stand 24 hours before checking that they are sealed properly. Place any unsealed jars into the refrigerator immediately. Store jars in a cool dark location after removing the bands. By removing the bands, you will be able to notice if at any time during storage the lids become unsealed and thus not edible.
To remove water stains on lids before marking the type and date of jam, take a cloth dipped in vinegar and wipe the lid.
In the second batch I made, I placed one cinnamon stick to add a little flavor. You can also add a vanilla bean or the apricot kernels in a stainless-steel tea strainer to compliment the flavor of the apricots. You can safely add up to 1 teaspoon of flavoring or herb to a jam or jelly recipe.
Because the Blenheim apricot season is so short, making jam is a great way to savor this flavor year-round and your friends will be happy when you bring over a jar of this delicious fruit. Enjoy!

In the last few months, the UC Master Food Preserver Program in the County of San Luis Obispo has received a couple of donations to support our mission to teach research-based practices of safe home food preservation to the residents of San Luis Obispo County. In one instance, a local community organization donates several cases of wine as the COVID-19 pandemic meant they would not be able to use the wine at any events this year. Last week, we received quite a few pounds of figs that otherwise would have been treated as food waste. With these donations, we knew the perfect recipe to make: Rosemary, Fig, and Red Wine Jam a safe, home-based recipe from Ball®.
The first step was to sort and clean the figs. Figs that were spoiled were composted. The rest of the figs were washed, wiped with clean towels, and then destemmed. Fig skin is very thin, so I did not scrub them with a vegetable brush.
Since we had so many figs, I decided to make 4 batches of jam. The second step was to harvest and wash the whole rosemary leaves, after removing them from the stems. I brought two tablespoons of rosemary leaves and half a bottle of red wine to a simmer. The herbaceous and berry scents filled the kitchen with an invigorating fragrance, which I enjoyed while moving on to prepare the figs.

The recipe indicated that the figs needed to be finely chopped. I was surprised at how long it took to chop the figs for the first batch. Once I completed this first batch of jam, I also realized that I had chopped them larger than desired.
So for the next batch, I decided to use a food processor, making the chopping much faster and providing a more consistent result. After cutting the figs, I moved them into a large enameled pot on the stove, adding pectin, and bottled lemon juice, which I brought to a vigorous boil. The lemon juice is an important ingredient in this fig-based recipe to ensure that there is enough acid to make the product safe to consume after canning.

Then I measured the sugar. With this large volume of sugar, the jam would make a wonderful seasonal treat rather than as a daily complement to breakfast. While I brought the mixture back to a boil, I started to pull the canning jars out of the boiling water canner, so they would be hot when I added the jam.

Since this jam has so much sugar, the jars were very sticky after I filled them. I cleaned all the rims and the sides of the jars with a warm wet towel. Then, I added the lids and hand tightened the rings. To save energy and time, I used an atmospheric steam canner following the processing time in the recipe.

After pulling the jars out of the canner, I left them to set undisturbed for 24 hours. The next day, I took off the rings and checked the seals on all the jars. Two of the jars did not seal, so I cleaned the jar rims and replaced with new lids and rings. Then, I re-processed these two jars in the atmospheric steam canner for a second time. They still did not seal, so I stored them in the fridge.
These jams would make a lovely thank you gift or holiday present. The recipe suggests pairing the jam with blue cheese, which sounds delicious on homemade sourdough crackers. You can find this jam recipe on the Ball® website freshpreserving.com.
