This cannabis jam recipe makes a small batch of raspberry freezer jam and stirs the infusion in only after cooking. That spares it the hard boil, and measuring the finished jam first keeps the dose per tablespoon simple.
Dosing: total mg divided by tablespoons
Divide the THC in your infusion by the tablespoons of finished jam. This batch makes about 2 1/2 cups, or 40 tablespoons, so 100 mg gives roughly 2.5 mg per level tablespoon; half of a tincture labeled 200 mg per bottle would do it. Stir it in for a full minute, then count one level tablespoon as a serving and give it at least 2 hours; our THC dosage guide explains the wait.
What you need
Raspberries, fresh or thawed frozen, sugar warmed in a low oven so it dissolves fast, and lemon juice. For the infusion, use a glycerin or alcohol tincture or melted canna-coconut oil. Selection varies by store, so check your local High Society store's menu for tinctures.
The cannabis jam recipe, step by step
Bring the berries to a boil, mashing as they soften, then add the warm sugar and lemon juice and boil hard, stirring often. Start testing after about 5 minutes. The jam is ready at 220°F at sea level, minus 2°F per 1,000 feet of elevation. Or spoon a little onto a cold plate and set it in the freezer for a few minutes; if it gels, the jam is ready. Let it cool off the heat for 5 minutes, then stir in the infusion.
Choosing an infusion
THC dissolves in alcohol, glycerin and fats, so each one carries it into a jam that's mostly fruit, sugar and water.
| Infusion | Taste | Texture |
|---|---|---|
| Glycerin tincture | Sweet, mild | Mixes in easily |
| Alcohol tincture | Sharper, a little boozy | Mixes in easily |
| Canna-coconut oil | Mild | Firms up and can fleck when cold |
See our tincture guide and canna oil recipe for each base.
Storage and labeling
This isn't a canning recipe, so keep the jam in the fridge or freezer. Ohio State University Extension gives uncooked freezer jams up to three weeks refrigerated or a year frozen, and an opened jar a few days. If you used infused oil, freeze every jar but the open one. Mark each lid "infused," with the mg per tablespoon and the date, and keep the jars apart from your regular jam, out of reach of curious kids and pets.
