Instructions

Place the strawberries in a large bowl and mash them so that just a few chunks remain. I like to do this with a potato masher but you can also use a fork. Mix in the sugar and let sit for 10 minutes.

After 10 minutes, stir together the boiling water and liquid pectin and mix it into the strawberries. Stir in the lemon juice. Let sit for 5 minutes.

Pour the mixture into clean glass jars and cover/ seal. Let sit on the counter, at room temperature, for 24 hours, and then place in the freezer.

To enjoy, remove a jar the night before you’d like to enjoy it! I let mine sit on the counter overnight and it’s perfect in the morning.

The jam will last in the fridge for about 4 weeks or in the freezer for up to a year.

Notes

Pectin- I used a 3oz packet of Certo liquid fruit pectin (see photo above for reference)- I’ve found it at most major grocery stores.

Other fruit- I haven’t personally tried this with other berries, but I’ve heard of people swapping out some of the strawberries for other berries and the recipe still works great.

Tips & Tricks (5)

Macerate Berries First 🍓
Toss fresh strawberries with sugar 15-20 minutes before cooking to release their natural juices, creating a more flavorful and naturally pectin-rich base for your jam.
Crush Berries Unevenly 🔨
Use a potato masher to create a mix of chunky pieces and smaller bits rather than pureeing completely—this gives you authentic jam texture with both substance and spreadability.
Add Lemon Juice Last ✨
Stir in lemon juice after cooking rather than before to preserve its bright, fresh acidity and prevent it from breaking down during the heating process.
Master the Pectin Timing ⏱️
Bring your mixture to a rolling boil before adding liquid pectin, then boil for exactly 1-2 minutes—over-cooking destroys pectin's gelling power, while under-cooking results in runny jam.
Chill Test Before Freezing 🧊
Place a spoonful on a frozen plate for 2-3 minutes to test consistency before transferring to containers—this ensures proper set without relying on guesswork or failed batches.
