Can I Double the Recipe in My Slow Cooker?

Yes, you can double the recipe, but make sure your slow cooker can handle it without overflowing. It’s crucial not to overcrowd it to allow even cooking and proper heat circulation.

Slow Cooker Grape Jam Ingredients

• 1.7 kg / 3 lb 12 oz seedless grapes – I used equal quantities or red, black & green grapes
• 1 kg / 2 lb 3 oz granulated sugar
• 3 tbsp lemon juice

How To Make Slow Cooker Grape Jam

1. Prepare Your Ingredients: Combine the grapes, sugar, and lemon juice in a large slow cooker. Ensure your cooker is large enough to mix these comfortably.
2. Heat It Up Slowly: Set your slow cooker on low to gently dissolve the sugar without rushing. Stir the mix now and then to prevent sticking.
3. Mash the Grapes: As the grapes warm up, they’ll begin to release their juices. Take a potato masher and gently mash the grapes to help them along. Don’t go too wild; just enough to break them up.
4. Blend the Mixture: Once the sugar has completely dissolved, which should take about 20 minutes, turn off the cooker. Use a stick blender to puree the grapes until the mixture looks like a smooth juice.
5. Boil and Set the Jam: Turn the slow cooker to high and bring the mixture to a boil. Let it boil vigorously for about 25 minutes, stirring often to keep it from scorching. If the jam isn’t setting as expected, you might adjust the time by a couple of minutes.
6. Test the Set: To check if your jam is ready, drop a few spoonfuls on a chilled saucer and pop it back in the fridge for a minute. Push your finger through the jam — if it wrinkles, it’s set. If not, give it a few more minutes to boil and test again.
7. Jar Your Jam: Once set, ladle the hot jam into sterilized jars. Seal them tightly with lids and let them cool before storing them in a cool, dry place.

Is This Grape Jam Recipe Suitable for Canning?

Recipe Tips

• Sugar variety works wonders: Don’t be afraid to mix things up with your sugar choices; try using half-brown sugar for a deeper flavor that compliments the natural tartness of the grapes.
• Stir occasionally, not constantly: Let the slow cooker do its thing! A gentle stir every now and then is enough to keep things from sticking without you standing guard.
• Mash those grapes well: Getting the right consistency starts with a good mash. If you prefer chunkier jam, go easy on the mashing; if you like it smoother, give those grapes a thorough workout.

Recipe Variations

• Spice it up: Add a cinnamon stick or a few cloves during cooking to introduce a warm spice flavor, perfect for those chilly months when a slice of toast needs a bit more comfort.
• Berry delightful twist: Mix in some raspberries or blackberries for a berry version that’s bursting with flavor and vibrant color that screams gourmet without the fuss.
• Citrus zing: Throw in the zest of one orange or lemon during the cooking process to add a zesty punch that cuts through the sweetness and brings a fresh brightness to your jam.

What To Serve With Grape Jam

Serve your Grape Jam with vanilla bean panna cotta, brie on toasted baguette slices, dark chocolate desserts, almond flour pancakes, and oatmeal cookies.

You can also pair it with pecan pie, and baked brie with walnuts, enhancing the flavors with a sweet touch.

How To Store Leftover Grape Jam

In The Fridge:

Store your Grape Jam in a clean, airtight container to maintain its freshness. Ensure the lid is tightly sealed to prevent any moisture or odors from entering. This setup will keep the jam fresh for up to 3 weeks.

In The Freezer:

Grape Jam should not be stored in the freezer as freezing can alter its texture and flavor. The high sugar content can prevent proper freezing, leading to a syrupy consistency when thawed.
