Step 5: Mix the pulp, sugar, lemon peel, and salt in a saucepan. Cook the pulp for about 5 - 10 minutes until softened, and the sugar is dissolved.
Step 6: Pass the softened pulp through a sieve to remove the seeds (doesn’t need to be a fine sieve, just small enough to catch all the seeds) and place it back in the saucepan.
Step 7: The lemon peel will also be caught in the sieve. Remove this and add it back into the saucepan.
Step 8: Add the concord grape skins into a blender and add about 1 - 2 cups of the pulp. Blend until smooth.
Step 9: OPTIONAL - You can pass this grape skin mixture through a sieve as well to have a super smooth jam, but it's not necessary.
Step 10: Add the concord grape skin mix (sieved or not), to the rest of the pulp in the saucepan.
Step 11: Cook over medium heat, and bring the mix to a boil. Stir frequently to make sure that the jam doesn't stick to the bottom of the pan.
Step 12: Cook for about 45 -50 minutes. Do the jelly test (as described below) at around 45 minutes - place a small amount of jam on a freezing cold saucer. Put it back in the freezer for about 1 minute (until the grape jam has cooled down, but not frozen). Then track your finger through the jam to test the consistency.
Step 13: If the parted jam flows back easily and meets in the middle again, then it’s too runny. A slightly thicker consistency where the jelly/jam flows back a little, but it's slow and doesn't meet in the middle again, is the perfect consistency for me.
Step 14: If the grape jelly is still a tad too runny, cook for a few minutes longer. Test the jelly every 5 - 10 minutes until you get the desired consistency. I don’t cook for longer than 60 minutes because this overcooks the jelly/jam on my stove. The time may change according to your stove and pan that you use.
Step 15: Remove the lemon peel, and let the jam cool down slightly.
Step 16: While the jam is still hot, ladle the jam into hot sterilized jars. Close the jars with sterilized lids, and allow the jam to cool down completely. Store in the fridge overnight and use AFTER the jam has rested for at least 6 hours.
Step 17: Store in the fridge for up to 3 months. But once opened use within 2 weeks.
Step 1: Wash the jars and lids before sterilizing them. Place the jars and lids on a steaming rack, and fill the pot with water. Bring the water to a boil, and allow the jars and lids to boil for 10 minutes in the water. Remove the jars from the pot (use tongs), and place them on a tray. Fill the jars immediately with the hot jam and close with the lids.
Step 2: You can start sterilizing the jars while the jam is being cooked. Then leave the jars in the hot water, until you’re ready to store away the jam.
