Few things in life bring the taste of summer back like homemade jam. Each time I twist open a jar of this Mixed Berry and Vanilla Jam, a warm wave of memories—berry-picking in sunlit fields, the scent of simmering fruit, and that first spoonful spread on fresh bread—comes flooding back. There’s something so deeply satisfying about turning fresh berries into a bright, flavorful jam that fills the kitchen with the aroma of sweet berries and warm vanilla.

This is so much more than a jam recipe; it’s about clinging to the sweetness of those long summer days. From how to pick the best berries to how to achieve the perfect jam consistency, everything youwill need to know to make this jam is right here.
Selecting the Best Berries for Jam
This recipe involves strawberries, blueberries, raspberries, and blackberries. Talking about jam, the ripe and sweetones are always way better. Strawberries provide the major flavor and give a tasteful, slightly tangy kick. Blueberries bring about dark color and sweetness into the mix of other berries, while raspberries and blackberries add a little tartness and a nice purple hue for great color toyour jam and tasteful, too.

If you’re anywhere in the middle of berry season, get fresh berries out, those that are super ripe, those are gonna give the best taste. Frozen berries are great too, though, because they can maintain a degree of sweetness and texture when it’s dead winter. Make sure to let them thaw a bit before you work with them.
Adding a Touch of Vanilla for Depth
The vanilla in this jam takes what would otherwise be a fairlystraightforward berry preserve and elevates it to something that just shines with warmth and depth, balancing out the tartness of the berries. You can make this using either a fresh vanilla bean or pure vanilla extract. While vanilla beans will give an unmistakable, subtle, slightly natural flavor with those tiny specks of seeds in the jam, extract works beautifully if you’re short of time or can’t find vanilla beans.
The Simple Art of Making Jam
This isn’t hard to make, nor does it take very much time, probably about 40 minutes. Herein is how to handle each step so that you will have a perfect batch:
Preparing the Berries
Wash all the berries well and let them drain well. Wash, hull, and cut upstrawberries if they are large so that they will cook down as easily as the smaller blueberries, raspberries and blackberries. This way, you can retain most of the berries whole so as to have a nice texture with achunk of fruit in every spoonful.
Cooking the Jam to Perfection
So, in go the berries and the sugar into a big, heavy-bottom pot, wherethe sugar pulls the juices out of the berries and creates this outstandingsweet syrup for the jam. And if you add that splash of fresh lemon juice,that really balances it out but also helps the jam to set, since it activates the natural pectins in the berries.
As this heats up, the mixture will start to bubble. Reduce the heat tolow and stir occasionally, using a spoon or potato masher to lightlypress the berries, helping them release their juices as they startsoftening, which creates a chunky fruit-smooth jam mix.
Knowing When Your Jam is Ready
The most frequent question one can hear while jam preparation is, “How will I know it’s ready?” Well, there’s a pretty easy test for this: after the jam has been at a simmer for about 25-30 minutes, just grab a little spoonful and put it on a chilled plate. Give it a minute to cool, then swipe your finger through. If the jam holds its shape and doesn’t justflow back together, it has reached the thickening stage and is ready forthe jars! If using vanilla extract rather than a vanilla bean, now is the time to add it in, so you don’t cook off too much of the fragrance.
Stashing Your Jam For short-term storage, this suffices: just fill the hot jam into clean, sterilized jars, leaving a little headroom. If you want to store the jam for longer periods of time, put the jars in a boiling water bath for about 10 minutes to seal them properly. You will then be able to store the jam at room temperature for several months-just what youneed when you crave a little taste of summer.
Bonus Tips for the Perfect Jam
- Balancing Sweetness and Tartness: If your berries are particularly sweet, you can reduce the sugar slightly. But remember, sugar helps preserve the jam and contributes to its thick texture.
- Skimming Foam: During cooking, foam may rise to the top. Skimming this off helps create a smoother, clearer jam.
- Testing Jam Consistency: Another great way to test is by using a candy thermometer. When the mixture reaches around 220°F (104°C), it’s generally thick enough to set as jam.
- Texture Options: For a smoother jam, mash the berries thoroughly as they cook. If you love a chunky texture, leave more berries whole.

Mixed Berry and Vanilla Jam Recipe
Course: Homemade Spreads u0026amp; Fillings4 cups
servings10
minutes25
minutes60 per tbsp
kcalIngredients
2 cups strawberries (hulled and chopped)
1 cup blueberries
1 cup raspberries
1 cup blackberries
2 cups granulated sugar
1 tablespoon fresh lemon juice
1 vanilla bean (split lengthwise) or 1 teaspoon pure vanilla extract
Makes about 4 cups of jam.
Steps
- Step 1: Prepare the Berries
- Rinse all the berries under cold water and let them drain thoroughly.
- Hull and chop the strawberries into smaller pieces if they are large. Leave the blueberries, raspberries, and blackberries whole.
- Step 2: Combine Ingredients
- In a large, heavy-bottomed pot, combine the strawberries, blueberries, raspberries, blackberries, and granulated sugar. Stir well to coat the berries in sugar.
- Add the lemon juice and the split vanilla bean (if using vanilla extract, wait to add it at the end).
- Step 3: Cook the Jam
- Place the pot over medium heat and cook, stirring occasionally, until the mixture begins to bubble.
- Once bubbling, reduce the heat to medium-low and let the mixture simmer. Use a spoon to mash some of the berries as they soften, releasing their juices.
- Stir frequently to prevent sticking, and skim off any foam that forms on top.
- Continue simmering for about 25–30 minutes, or until the jam thickens. To test the jam’s consistency, place a small amount on a chilled plate and run your finger through it. If it holds its shape, it’s ready.
- If you’re using vanilla extract instead of a vanilla bean, stir it in now.
- Step 4: Remove the Vanilla Bean
- If you used a vanilla bean, remove it from the jam once the jam is cooked to your desired thickness. The tiny seeds will remain, infusing the jam with a subtle vanilla flavor.
- Step 5: Jar the Jam
- Pour the hot jam into sterilized jars, leaving a ¼-inch headspace. Carefully wipe the rims clean and seal with lids.
- If you plan to store the jam for an extended period, process the jars in a boiling water bath for 10 minutes. Otherwise, allow the jam to cool before refrigerating.
