This simple, two-ingredient raspberry jam recipe has an intense flavor that requires no added pectinand produces a small batch of three cups or three half-pints. When you have a bumper crop of homegrown raspberries, try making this jam with them. Raspberries have such a short shelf life, and they are rather delicate, so jam is a good use for them. If you don't have a garden full of berries, fresh from the market or frozen raspberries will do just as well.

The recipe has a lot of sugar, but it's not just to add required sweetness. Sugar acts as the preservative element to extend the shelf life of the jam. It's also needed to gel the jam; if you reduced the amount of sugar, you would need to use pectin to get the jam to set up, because raspberries, like strawberries, are not naturally very high in pectin.

The equipment you will need for this recipe includes a large pot, potato masher, canning jars and lids, and a water process canner or alternative sterilization set-up.

Ingredients

4 cups raspberries, fresh or frozen
2 cups granulated sugar

Combine the raspberries and sugar in a large stainless steel or enameled non-reactive pot. Cover and let them sit overnight. This maceration time releases the juices from the fruit and shortens the cooking time.
Sterilize the canning jars by boiling for 10 to 15 minutes in a hot water bath. Prepare the canning lids according to their directions.
Mash the fruit and sugar mixture with a potato masher to break up the berries. Place a plate in the refrigerator to chill for the gel test.
Bring the jam mixture to a boil over high heat, stirring often.
If foam forms on the surface, skim it off with a metal spoon or skimmer. Continue to boil, stirring, until the mixture reaches the gel point, about 20 minutes. If you use a candy thermometer, this is around 215 F.
Test your jam to see if it has gelled by taking the chilled plate, adding a spoonful of jam, and placing it in the freezer for 2 minutes. When you take it out, it is properly gelled if it doesn't run down the chilled plate, and when you drag your finger through it, the path remains intact.
Ladle the jam into the sterilized jars leaving 1/4-inch headspace. Cover with canning lids and process in a boiling water bath for 5 minutes.
Remove from the water bath and let drain on a towel-lined work surface. After you hear the "popping sound" indicating suction and a good seal, tighten the bands. Let cool completely and store in a cool, dark place for no more than a year for best flavor.

What Is the Best Way to Wash Raspberries?

Raspberries are very delicate, and if you run them under cold water they will undoubtedly get squished and lose the little structure that they have. There are a few schools of thought on this. One suggests placing them in a colander or fine-mesh sieve and gently run cool water over them. Then, remove them to a clean kitchen towel, perhaps lined on a rimmed baking sheet if you're worried about them rolling away, and gently pat them dry with paper towels.

If the raspberries look extra delicate, which can be the case in the height of summer, especially if you have picked them yourself, place them in a colander and gently submerge the colander in cool water. Swish them around a little and lift the colander out. Dry as directed, on a towel-lined baking sheet.

Tips

If you don't want to go through the canning process, you can simply refrigerate the jam for up to three weeks or freeze it for up to one year.
Look for very ripe fresh raspberries, as they will lend the most flavor to the jam. Cooking underripe berries won't make them taste better.
Frozen raspberries are a good choice as they are often frozen when they are very ripe. If you're worried about fruit that has been sprayed with chemicals or pesticides,you can find organic frozen berries at most supermarkets.
