Servings: 112 servings (1 tablespoon)
Calories: 39kcal
Ingredients
- 6 cups red raspberries
- 5 ½ cups granulated sugar
- 1 (1.75 ounce / 49 gram) box Sure Jell Original Fruit Pectin
Equipment
- Mason Jars (seven ½-pint jars OR one ½-pint jar and three pint jars), or other freezer safe containers
Instructions
- Place raspberries in a large bowl, then use a potato masher (or the back of a spoon) to crush them.
- Use a dry measuring cup to measure out exactly 3 cups crushed raspberries. (If you have extra berries, reserve for another use.)
- Stir sugar into raspberries, mixing well. Let stand for 10 minutes, stirring occasionally.
- After 10 minutes is up, combine pectin and ¾ cup water in a small pot. Bring mixture to a boil on high heat, stirring constantly. Boil for 1 minute, stirring constantly, then remove from heat.
- Mix hot pectin into raspberry mixture, then continue stirring for 3 minutes, or until the sugar is totally dissolved. (This may take longer than 3 minutes.)
- Transfer jam to jars, leaving ½-inch of headspace at top. Cover with lids.
- Let jam sit at room temperature for 24 hours, or until set.
- Once jam is set, refrigerate for up to 3 weeks, or freeze for up to 1 year. Enjoy!
Notes
If you prefer jam with less seeds, press half of the crushed berries through a fine mesh strainer to remove the seeds.
I used about 1 ½ pounds (680 grams) of raspberries to make this recipe, which yielded exactly enough berries. If you're not sure how much to buy, always err on the side of buying extra. If you have leftovers, you can always use the berries for another recipe.
This Freezer Jam recipe is easy to make, but it's a bit of a science. It's important to follow all directions carefully and exactly as written, measure accurately, and do not make any substitutions.
Jam is considered "set" when it has thickened and is no longer runny. Do keep in mind though that Freezer Jam does not get as thick as commercially made jam.
Sure Jell Pectin can be found in most U.S. grocery stores (look for it in the baking aisle) or online. There are different brands of pectin, and they are not interchangeable. If you happen to purchase another brand, you can use this recipe as a guide, but you should follow the directions included with the box.
If you'd like to make this jam with less sugar, then use Sure Jell Less Sugar Pectin instead, and follow the directions on the package.
