Overview
If you’re searching for the best strawberry jam ever, the secret is using ripe, flavorful strawberries, the proper balance of sugar, and either commercial pectin or enough natural pectin and acid to achieve the perfect consistency. Homemade strawberry jam stands out because it delivers a brighter, fresher berry flavor than most store-bought varieties while allowing you to control sweetness and ingredients. For long-term pantry storage, always follow a tested water-bath canning method and avoid doubling recipes, as larger batches may not set properly. Many experienced jam makers also recommend using peak-season berries, gently crushing the fruit instead of pureeing it, and cooking only until the jam reaches the gel stage for the best texture and flavor.

The sweet aroma of homemade strawberry jam fills my kitchen, making it impossible not to crave a warm slice of toast generously topped with fresh strawberry jam. Every year, I prepare around 350 jars of jam, with strawberry, blueberry, and raspberry always being the most requested flavors. It may sound like a lot, but there is a good reason behind it. I love sharing homemade jam with family, friends, and the amazing staff in the emergency department where I work. Every Christmas, everyone on my gift list receives a jar of homemade jam, and somehow that list keeps getting longer. That is how my annual jam-making tradition has grown to nearly 350 jars each year.
Making homemade jam is surprisingly simple—which is a good thing when you have 350 jars on your canning list.
This recipe is easy to scale up or down, whether you’re making a small batch or preserving a large harvest. Today was a big canning day, yielding 54 jars of Fresh Strawberry Jam from a single kettle of ripe strawberries. Delicious!
Perfectly ripe berries, harvested at peak freshness, are the secret to making flavorful homemade jam. This recipe uses fruit pectin as the thickening agent, making the jam completely vegan since it contains no animal-derived ingredients. Fruit pectin is widely available in most grocery stores under brands such as Sure-Jell or RealFruit Pectin. The measurements in this recipe are designed for one full box of pectin and yield approximately eight 1/2-pint jars of jam. If you only have enough berries for a half batch, simply use 4 tablespoons of pectin and adjust the remaining ingredients accordingly.
Fresh Strawberry Jam
Equipment
- 1/2 pint jam/jelly jars with lids and rings You will need 8 or 9 jars
- This page contains Amazon affiliate links. If you click a link, I may earn a small commission from qualifying purchases at no extra cost to you
Ingredients
- 5 cups strawberries washed, stems removed, and chopped
- 7 cups sugar granulated
- 4 tbsp fruit pectin
- 2 Tbsp. lemon juice use bottled not fresh
Instructions
- Add the crushed berries to a large kettle. The kettle shouldn't be more than 1/2 full.
- Add the lemon juice to the crushed berries. The lemon juice helps the jam jell and add acidity to lower the ph and prevent the growth of bacteria.
- Add the Fruit Pectin to the berries and stir well.
- Stir constantly to prevent scorching and bring to a full rolling boil that can't be stirred down. Boiling gives lots of bubbles on the top of the jam. A rolling boil that can't be stirred down means you can't make the bubbles go away by vigorous stirring. Boil for 1 minute.
- Add the sugar all at once and stir in. Stir constantly to bring to a second rolling boil that can't be stirred down. Boil a full minute again.
- Remove from the heat. Skim off the foam and discard. Fill the jam jars. Leave about 1/2 inch of space between the jam and the top of the jar. You will need 9 half-pint mason jars.
- Put the jars in a water bath canner. Cover the jars with water and bring to a boil in a water bath canner. Boil the jars for 20 minutes. Remove the jars from the water and let them cool completely.
- 8. Once the jars have cooled test the lids to make sure the jars are sealed. Test for a seal by pressing down in the center of the lid with your finger. If the lid springs back up when you release your finger the jar isn't sealed. If the jar doesn't seal, take off the lid and check the jar rim to make sure it is not chipped. Discard the lid and put a new lid on the jar. Reheat the jar in the water batch
- Optional: a TBS. of butter or oil helps break up the surface tension of the jam and minimizes the foam you will have to skim and discard before you fill the jars.
