Kids Blackberry Jam Recipe in 40 Minutes

Instructions:

1. Rinse the blackberries under cold water and pat them dry.
2. Place the berries in a large heavy-bottomed pot and use a potato masher to gently crush them.
3. Stir in the granulated sugar and lemon juice over medium heat.
4. Bring the mixture to a gentle boil, stirring constantly to ensure the sugar dissolves completely.
5. Lower the heat to a simmer and let the mixture bubble for 20–30 minutes until it reaches a deep, glossy mahogany color and bubbles become larger and heavier.
6. Perform the plate test: Drop a teaspoon of jam onto a frozen plate, let it sit for 30 seconds, and push it with your finger; if it wrinkles, it is ready.
7. Carefully pour the hot jam into sterilized jars, leaving about ¼ inch of headspace.
8. Wipe the rims clean, seal tightly with lids, and let cool completely on the counter before refrigerating.
