- strawberries

- 29.6 ml Pomona's calcium water
- 946 ml sugar or vanilla sugar
- 19.7 ml Pomona's Universal Pectin powder
Prepare
- 4 vanilla beans, cut lengthwise
Let's Cook
-
Step 1.
Prepare the calcium water: In a small bowl or jar with a lid, combine 1/2 teaspoon calcium powder and 1/2 cup water. Shake well to dissolve. Store in the refrigerator and shake before using; this makes enough for several batches.
-
Step 2.
Sterilize your jars, prepare bands and lids, and have all canning tools ready.
-
Step 3.
Hull the strawberries and cut the largest berries in half. Leave smaller ones whole if you like a chunky texture, or halve them too. You should have about 16 cups of berries.
-
Step 4.
In a large stockpot, combine the berries, lemon juice, and calcium water. Cut the vanilla beans lengthwise, scrape out the seeds with a sharp paring knife, and add both seeds and pods to the pot.
-
Step 5.
In a medium bowl, stir together the sugar and Pomona's Universal Pectin powder until well combined.
-
Step 6.
Over medium-high heat, bring the fruit mixture to a boil, stirring frequently to prevent scorching. Once boiling, add the sugar-pectin mixture and stir to dissolve. Reduce the heat to low and simmer for 20 to 25 minutes, stirring occasionally, until the jam thickens.
-
Step 7.
Ladle the hot jam into sterilized jars, leaving 1/4 inch of headspace. Wipe the rims clean, place lids on top, and screw on bands until fingertip-tight.
-
Step 8.
Process the jars in a water-bath canner according to the manufacturer's instructions. Store in the refrigerator or pantry for up to 1 year.
