Notes for August 2017: Blueberries and peaches are going still in northern and cooler areas, but are mostly finished in the Deep South. Blackberries, figs, and raspberries are in season now. Tomatoes are going strong, although the crop is way diminished in rainy areas like the southeast. Strawberries are finished, except in the far north, and if the farm planted Day Neutral varieties. Early apples, like Gala, are about to start!

Sometimes after you have canned your jam, jelly or other preserves and let it cool, you open a jar, only to find it hasn't set properly an d is too runny! If your jam or jelly turns out too soft or runny, don't despair, and don't throw it away! It can be fixed! Here's how!
If the jam is too thick, before you put it in the jars, just heat 1 or 2 cups of grape juice (or any other fruit juice of similar or neutral taste, like apple or white grape) to boiling. Then, gradually pour and stir it in until you reach the desired consistency, then continue canning!
If the jars are already sealed / canned, then when you use them, just stir in a little grape juice until you reach the desired thickness.
If the jam turns out too runny, that is a little different to fix. Here's how:

It takes 3 ingredients for jams and jellies to set: pectin, sugar and acidity. The amount of pectin that is naturally occurring in the fruit varies from one type of fruit to another and by ripeness (counter intuitively, unripe contains more pectin). See this page for more about pectin in fruit. It takes the right balance, and sufficient amounts of each of pectin, sugar and acidity to result in a firm jam or jelly. And there are two conditions that must be met: the right amount of heat for the right amount of time. It takes a brief period (1 minute) of a hard boil, to provide enough heat to bring the three together. Generally speaking, if your jam doesn't firm up, you were short in pectin, sugar or acidity or didn't get a hard boil. We will correct that when we remake the jam or jelly!
Finally, you CANNOT reliably make batches of jam larger than 6 cups of raw fruit (of course, but the time you add sweetener, lemon juice, etc. it will be more than that). No matter how much you stir, you won't get effective heat penetration in larger batches, so some pectin gets overcooked, while other pectin is not activated. So, to reliably fix the jam, you will need to split it into batches of less than 7 cups each.
Measure the jam or jelly to be recooked. Work with no more than 4 to 6 cups
at a time. Check all the jars from the batch - if one failed to set, most or all
probably failed. You can check by just turning them upside down and seeing
how quickly the jam or jelly shlooshes* around in the jar.
(* - Schloosh - from the old German verb, "schlushen" meaning to flop around like a freshly caught trout)
Add up the volumes of all the jars to be reworked, to figure out the size of the batch (in quarts) for step 2.
1 qt = 32 oz = 2 pints = four 8oz jars = eight 4oz jars).
Open the jars to be fixed and dump them all into a large pot.
Since you will probably want to reuse the jars, get the now emptied jars washing in the dishwasher.
If you are using powdered pectin:
For each quart of jam or jelly to be fixed, mix ¼ cup sugar, ¼ cup water or white grape juice, 2 tablespoons bottled lemon juice, and 4 teaspoons powdered pectin in a large pot. So, if you made a batch of jam and have 10 eight-ounce jars that didn't set, that would be an average batch (10 cups or 2.5 quarts). For that average batch of about 2.5 quarts total, you would need 2/3 cups sugar, 2/3 cups water or juice and about 1/3 cup lemon juice, plus about 3/4 of a box of pectin, preferably the no-sugar variety.
This table may help you with calculations:
|Amount of jam or
jelly to re-make
|2 cups (1pint)||4 teaspoons||4 teaspoons||1 tablespoon||2 teaspoons|
|3 cups||6 teaspoons||6 teaspoons||1.5 tablespoons||3 teaspoons|
|4 cups (1 quart)||1/4 cup||1/4 cup||2 tablespoons||4 teaspoons|
|5 cups||1/4 cup||1/4 cup||2.5 tablespoons||5 teaspoons|
|6 cups (1.5 quarts)||1/3 cup||1/3 cup||3 tablespoons||6 teaspoons|
|7 cups||1/3 cup||1/3 cup||3.5 tablespoons||7 teaspoons|
|8 cups (2 quarts)||1/2 cup||1/2 cup||4 tablespoons||8 teaspoons|
Remember, if you have more than 6 cupo of jam,
If you are using liquid pectin:
For each quart of jam or jelly, measure ¾ cup sugar, 2 tablespoons bottled lemon juice, and 2 tablespoons liquid pectin in a large pot.
Add the jam or jelly to the pectin mixture and bring it to a rolling boil again, over high heat, stirring constantly. Keep in mind that one reason jams and jellies don't set is because people try to double batches, and there is non-uniform heating. That results in some pectin becoming over-cooked and some pectin in the batch is under cooked. Never make a new batch of jam or jelly starting with more than 6 cups of crushed fresh or frozen fruit; and never try to remake a batch larger than 2.5 quarts.
Once it is a rolling boil, boil hard for 45 to 60 seconds (1 minute).
I keep a metal tablespoon sitting in a glass of ice water, take it out, shake off the water and then take a half spoonful of the mix and let it cool to room temperature on the spoon. in a minute or so. If it thickens up to the consistency I like, then I know the jam is ready. If not, I mix in a little more pectin (about 1/4 to 1/2 of another package) and bring it to a boil again for 1 minute.
Remove from heat, and quickly skim the foam off jam or jelly.
Fill sterile jars (automatic dishwashers often have a sanitize setting, otherwise, wash and dry and add 5 minutes to the processing time), leaving ¼-inch headspace. Adjust new lids (don't reuse the previous lids, they are single use) and...
... process as recommended in the table below.
|Recommended process time for Remade Soft Jellies in a boiling-water canner.|
|Process Time at Altitudes of|
|Jar Size*||0 - 1,000 ft||1,001 - 6,000 ft||Above 6,000 ft|
|Half-pints or pints||5 min||10||15|
*Larger sizes are generally not recommended for jams and jellies
