How To Make And Can Blackcurrant Jostaberry Jelly

Views: 6

Back at home, we started having doubts. Yes, these berries looked like purple gooseberries. However, they were much, much smaller. After some diligent online research, we discovered they were actually jostaberries—a cross between gooseberries and blackcurrants.

Ribes × nidigrolaria, commonly called jostaberry, is a hybrid, deciduous, fruiting shrub resulting from a complex cross between two hybrid Ribes: a powdery mildew resistant selection of R. divaricatum (spreading gooseberry or coastal black gooseberry) × R. nigrum (black current), and the white pine blister rust resistant R. uva-crispa (European gooseberry) × R. nigrum.

So, what do you do when you end up with jostaberries instead of gooseberries? The answer really depends on the type of jostaberries you have. Be that as it may, we went ahead with combining the two berries and making a blackcurrant jostaberry jelly. Lo and behold, it turned out to be a good choice.

Our blackcurrant jostaberry jelly is sweet and tangy, a pleasant surprise that made our original plan even better.

We are glad you asked! Surprisingly, the answer is “it depends”. The jostaberries we picked had a distinct gooseberry flavor. Fortunatelly, they weren’t tart like blackcurrants but still carried that earthy note typical of blackcurrants. Overall, our jostaberries tasted more like gooseberries. However, this isn’t always the case since there are many different jostaberry hybrids. If you have jostaberries and want to combine them with other berries to make jam or jelly, we strongly recommend tasting them first to ensure their flavor match your expectations.

The specified in this jelly recipe quantity of ingredients should yield enough jelly to fill three 8 oz. (250 ml.) mason jars. The final yield may vary based on your preferred level of jam doneness.

Ingredients

  • 1 lb. gooseberries 450 g.
  • 1 lb. blackcurrants 450 g.
  • 1.2 lb. sugar 550 g.
  • 1 tsp. pectin

Instructions

Preparing the berries:

  • Place the blackcurrants and jostaberries in a large pot or salad spinner. Fill it with water and let the berries soak for 5 minutes to loosen any debris and leaves. Rinse thoroughly until the water runs clear.
  • Because we only need juice for this preserve, there’s no need to remove the stems and blossom ends from either the blackcurrants or jostaberries.

Rendering the blackcurrant and jostaberry juices:

  • Place the blackcurrants and jostaberries into a suitably sized pot and add roughly one-third of the sugar required for this recipe.
  • Use a potato masher to mash the berries with the sugar.
  • Cover the pot and let it sit for at least 8 hours or overnight. This allows the sugar to draw out the juices from the berries, which is essential for making the jelly.
  • After the resting period, you should see plenty of berry juices in the pot. Bring the berries and their juices to a boil over medium heat, stirring often to dissolve the sugar.
  • Don’t worry about skimming the foam at this step.
  • Once boiling, lower the heat to medium-low and cook for 15 minutes.
  • Turn off the heat and use a fine mesh strainer to strain the blackcurrant and jostaberry juices into a separate pot. We will use these juices to make the jelly. You can discard the berry pulp or use it to make a crusty pie.

Making the Blackcurrant Jostaberry Jelly:

  • First, mix the remaining sugar and pectin together and set aside.
  • Pour the strained blackcurrant and jostaberry juices back into the pot and bring it to a boil.
  • Once boiling, reduce the heat to the lowest setting and let the liquid simmer for 10 more minutes.
  • As the liquid simmers, remove any impurities that form on the surface.
  • Add the sugar and pectin mixture to the simmering blackcurrant jostaberry liquid. Stir vigorously to ensure the sugar and pectin are well incorporated into the mixture.
  • Cook for an additional 15 minutes. If desired, perform a chilled plate test to check the jelly’s consistency. Cook for 5-10 minutes more if you prefer a denser jelly.
  • Pour the hot jelly into clean, sterilized canning jars. Process using your preferred canning method.

Frequently asked questions

Blackcurrant jostaberry jam tends to be moderately acidic. While both blackcurrants and jostaberries have natural acidity, they get balanced by the sweetness of the berries and the sugar added during the jam-making process. As a result, this jelly has a pleasantly tart and sweet flavor.

Keep in mind that the exact level of acidity in your jostaberry jelly will vary depending on the specific hybrid of jostaberry you end up using to make the recipe.

Indeed, both blackcurrants and jostaberries are naturally high in pectin! However, to make this jelly, we are not using the pulp of the berries, a source of these berries’ natural pectin. Therefore, you must add extra pectin to help this jelly set properly. By adding extra pectin, you ensure that your jelly achieves the right consistency and firmness. Without it, your jelly might end up too runny.
