My Amish neighbor brought jars of this stuff over, and I knew I had to copy the recipe!

 

Slow Cooker Amish Berry Jam

Let the slow cooker do the work. This gently cooked jam captures the bright flavor of fresh berries with minimal hands‑on time.

Yield: About 4–5 half‑pint jars
Prep time: 15 minutes
Cook time: 2½ hours (high)

Ingredients

Ingredient	Quantity
Mixed berries (fresh or frozen)	4 cups
Granulated sugar	3 cups
Lemon juice	1 Tbsp
Fruit pectin (powder)	1 package (1.75 oz)

---

Instructions

1. Prepare the berries

Wash the berries well.

• Strawberries: Remove green caps and quarter.

• Raspberries, blueberries, blackberries: Leave whole (small berries don't need cutting).

This step ensures a clean, enjoyable jam.

2. Mash in the slow cooker

Place the prepared berries into the slow cooker. Use a potato masher to gently mash them, releasing natural juices.
Don’t over‑mash — leave some berry texture for a more interesting jam.

3. Add sugar and lemon juice

Pour in the sugar and lemon juice. Stir thoroughly to combine, making sure the sugar is evenly distributed.

4. Slow cook (first stage)

Cover the slow cooker. Set to HIGH and cook for 2 hours, stirring occasionally to prevent sticking.

5. Add pectin and finish

After 2 hours, stir in the fruit pectin. Continue cooking on HIGH for another 30 minutes, stirring frequently.
The jam will thicken and become richer in color and translucence.

6. Jar the jam

Carefully ladle the hot jam into sterilized jars, leaving ¼ inch of headspace at the top.
Headspace is essential for a proper seal.

7. Process in a water bath

Seal the jars with lids. Process in a boiling water bath for 10 minutes (adjust for altitude if needed). This step ensures a vacuum seal and safe long‑term storage.

8. Cool and store

Remove jars from the water bath and let them cool completely at room temperature. You’ll hear a “pop” as each lid seals.
Store sealed jars in a cool, dark place. Refrigerate after opening.

Tips for Success

• Berries: Fresh or frozen both work. No need to thaw frozen berries.

• Sugar: Do not reduce the sugar – it helps the pectin set and preserves the jam.

• Pectin: Use standard powdered fruit pectin. Follow your brand’s guidelines if substituting.

• Stirring: Stir occasionally during the first 2 hours, more often during the final 30 minutes.

• Doneness test: Place a spoonful of jam on a cold plate. If it wrinkles when pushed, it’s ready.

Enjoy your homemade slow‑cooker jam — sweet, fruity, and wonderfully simple! 🫐🍓
