Why Make Homemade Strawberry Jam?
Making homemade strawberry jam is about more than just the final jar sitting on the shelf. It’s about slowing down long enough to enjoy the process, using real ingredients, and creating something that tastes like actual strawberries instead of overly sweet store-bought jam.
There’s something special about turning a few simple ingredients into jars of homemade jam that can be shared with family, tucked into the pantry, or opened months later and still taste like summer.
The Benefit of Making Your Own Jam
One of the biggest benefits of making your own jam is having complete control over the ingredients. You can choose fresh strawberries, adjust the sweetness to your liking, and avoid many of the additives and preservatives commonly found in store-bought versions.
Homemade jam also allows you to create a flavor that tastes brighter and more fruit-forward instead of overly sugary.
Why I Use Pomona’s Universal Pectin
For this recipe, I’m using Pomona’s Universal Pectin because it allows you to safely make jam with less sugar or alternative sweeteners like honey or maple syrup while still getting a beautiful set.
Unlike traditional pectins that rely heavily on large amounts of sugar, Pomona’s uses calcium water to help the jam set. That gives you much more flexibility in controlling the sweetness level while still safely water bath canning the jam.
It also helps the strawberry flavor shine through instead of being overwhelmed by sugar.
Lower Sugar and Sweetener Options
One of my favorite things about this recipe is that you can adjust the sweetness to fit your taste.
If you prefer a classic sweet jam, you can use more pure cane sugar. If you want a more fruit-forward jam, you can reduce the sugar significantly. Honey and maple syrup also work beautifully in this recipe.
The sweetness level changes the flavor of the jam, but with Pomona’s pectin, you still get a proper set without needing excessive amounts of sugar.
A Simple Seasonal Tradition
Making strawberry jam at home is also a wonderful way to connect with the season. Fresh strawberries at their peak are hard to beat, and the smell of simmering strawberries filling the kitchen feels like summer in a pot.
Whether you’re stocking your pantry, sharing jars with friends and family, or spooning it onto warm biscuits the next morning, homemade strawberry jam is one of those simple kitchen traditions that never really goes out of style.

Instructions
Prepare the Canner and Jars
Before starting the jam, prepare your water bath canner by filling it with enough water to cover the jars by at least 1 to 2 inches once submerged. Place the canner on the stove and begin heating the water.Wash your jars, lids, and bands in hot soapy water. Keep the jars hot until ready to use. You can keep them in the warm canner water or in a low oven while the jam cooks.Cook the Strawberries
Add the diced strawberries to a large heavy-bottomed pot over medium heat. As the strawberries begin to soften and release their juices, gently mash them to your preferred texture.Some people prefer a smoother jam while others like larger pieces of fruit.Allow the strawberries to cook for several minutes until juicy, softened, and fully heated through.Add the Calcium Water
Stir in the calcium water, kosher salt, and optional lemon juice if using.Bring the strawberries to a full rolling boil over medium-high heat.Mix the Pectin and Sweetener
In a separate bowl, thoroughly mix the pectin into your sweetener of choice. Mixing the pectin into the sweetener first helps prevent clumping when added to the hot strawberries.Finish the Jam
Slowly add the pectin mixture into the boiling strawberries while stirring constantly.Continue stirring and return the jam to a full rolling boil. Boil for 1 to 2 minutes, just until the pectin is fully dissolved.Avoid overcooking the jam, which can darken the color and dull the fresh strawberry flavor.Fill the Jars
Carefully ladle the hot jam into hot jars, leaving ¼ inch headspace.Use a clean bubble remover or utensil to remove any trapped air bubbles by gently sliding it around the inside edges of the jar.Because jam can be sticky, wipe the jar rims carefully with a cloth dipped in vinegar to help ensure a proper seal.Place the lids on the jars and apply the bands fingertip tight. Do not overtighten.Process the Jam
Carefully place the filled jars into the prepared water bath canner.Make sure the jars are covered with at least 1 to 2 inches of water.Cover the canner with the lid and bring the water to a full boil.Once boiling, process the jars for 10 minutes, adjusting for altitude if needed.When the processing time is complete, turn off the heat, remove the canner lid, and allow the jars to sit in the hot water for about 5 minutes before removing them. This helps reduce siphoning.Cool and Store
Carefully remove the jars and place them on a towel-lined counter.Allow the jars to cool undisturbed for 12 to 24 hours.As the jam cools, it will continue to thicken and set.Check the seals before storing. Any unsealed jars should be refrigerated and used first.
