Jelly contains gelatin, which is a processed form of collagen. Collagen is the most common protein found in humans and other mammals. When the gelatin is dissolved in hot water the bonds holding the collagen protein together are broken. Bromelain is a protein-digesting enzyme mixture found in the stem, fruit, and juice of the pineapple plant. Bromelain has also been used to medicinally for centuries as it has anti inflammatory properties.

If your recipe says to use a certain amount of mashed fruit, you need to mash the fruit before you measure it. If you measure the whole berries first you will end up with less fruit then the recipe calls for. This changes the ratio of sugar, fruit, and pectin. This can also happen if you remove the seeds from the pulp before making jelly. Another common reason for jam or jelly not setting is that there is something wrong with your pectin.
You should always store pectin in an airtight container to keep the moisture out. Also storing in a cool, dry place is best. If you added to much water when you were making the juice for jelly it creates a thinner juice that will need more pectin to properly jell. If you bought presweetened juice to make jelly with this also throw off the balance of sugar and pectin in the recipe and can cause it not to set.
If it has set it on your counter and let it return to room temperature. If it retains the jell constantly then you can refrigerate the rest of the jars until they have jelled. Then remove them to store in your pantry. This type of pectin is made to form a gel with little to no sugar.
If you were to use regular pectin you would have to add the full amount of sugar you used in your recipe over again making the finished product way to sweet. Place this in a large pot and mix together. Then pour the jam or jelly into the pot and bring the mixture to a rolling boil over high heat.
Remember to stir it constantly as it can burn easily. At the 1 minute stage take it out and place a little jam on an ice-cold spoon.
Let it cool down to room temperature on the spoon and see if it thickens up. If it has you know your jelly or jam is ready. As soon as it reaches a boil remove it from the heat and quickly add the pectin and lemon juice and stir to combine. Add lids and tighten until finger tight and process for 10 minutes or according to your altitude. Pour your soft jelly or jam into a medium-sized pot and add 2 tablespoons of lemon juice for each quart of jelly.
When the jelly is setting, remove the pot from the heat and skim off the foam. Need an easy way to keep track of your food storage? As an Amazon Associate and member of other affiliate programs, I earn from qualifying purchases. Please leave a comment on the blog or share a photo on Instagram.

Unfortunately, I tried to redo my jelly a 2nd time. Thank you! Good morning Kim, I appreciate your fabulous knowledge about so many things, but today my question is about jelly.
I measured everything, juice, lemon juice, surejell, sugar but reduced the sugar because it was so sweet.
