Homemade Mixed Berry Jam Recipe
Berry Good Times: Homemade Mixed Berry Jam 🍓🍇
Okay, so have you ever had a moment when you just need a taste of summer? Like, it’s freezing outside, and all you want is that burst of berry sweetness on a piece of toast? Yup, that’s my jam, literally! 😜

Okay, Let’s Talk Ingredients
So, here’s the lowdown on what you’ll need to make this deliciousness happen. You gotta grab:
– 4 cups raspberries (fresh is best but frozen works too—who am I to judge?)
– 4 cups blackberries (they’re like the underrated berry, you know?)
– 4 cups blueberries (because, why not?)
– 3 cups sugar (I know, I know, but it’s jam, not a salad)
– ¾ cup fresh lemon juice (just trust me on this, it balances everything out)
You might think that’s a lot of sugar, but it’s jam! It needs it! And don’t freak out about the lemons—grab a few at the store, it’s worth it!
So Here’s Why I Make This Constantly
Alright, real talk. I make this jam because it reminds me of summer mornings at my grandma’s house. She’d have toast ready with her homemade jam, and we’d sit outside, sticky fingers and all, listening to the birds and basically just living our best lives. One time, I made this for a brunch with friends, and they were like, “OMG, this is SO GOOD!” I literally felt like a kitchen rockstar! 😂
I mean, who doesn’t want to be the friend with the homemade jam? It’s like instant cred! Plus, it’s super easy to whip up, and you can just jar it and give it as gifts. Perfect for that one friend who’s always “supporting local” or whatever.

The One Trick That Changes Everything
Okay, here’s my game changer: let the berries and sugar sit together for about 10-15 minutes before cooking. It’s like they’re having a little berry party, and it helps release all that juice! Trust me, it’s magic. You’ll see the sugar start to dissolve, and it’ll make the whole jamming process smoother.
Don’t Mess This Up (My Top Tips)
– Don’t rush the cooking! If it says cook for 15 minutes, set a timer. Actually, set it for 18 minutes and check—just in case. 🙃
– If you see foam while cooking, just skim it off! It’s not cute, and it’ll make your jam look all weird.
– When you’re ladling it into jars, leave that ¼ inch of headspace! I learned that the hard way. Let’s just say, my first batch looked like a lava explosion. 😬
How to Keep Them From Disappearing (Or, How to Store Them)
Okay, so once you’ve got those jars packed up, you can store them in a cool, dark place for up to a year! Can you believe that? But, if one doesn’t seal right? Put that sucker in the fridge and eat it within a month—no waste, my friend! And trust me, it won’t last that long once you taste it.
If You Liked This, You’ll Probably Like These Too
If you’re into this, you’ll LOVE my peach preserves! Or, how about some strawberry rhubarb pie? Honestly, I could go on forever… just let me know and I’ll share ALL my recipes. 😍
So, what’s your favorite way to enjoy jam? On toast? In yogurt? Or are you one of those people who just eats it straight from the jar with a spoon? (No judgment here, that’s a whole vibe!) Let’s chat!

Ingredients
- 4 cups raspberries
Instructions
- Have ready 6 hot, sterilized half-pint jars and their lids.
- Place the berries and sugar in a large bowl. Gently stir together and let sit for 10-15 minutes.
- In a large nonreactive saucepan, gently stir together the berries and lemon juice. Bring to a boil over medium-high heat, reduce the heat to medium and cook, uncovered, stirring frequently and removing any foam, until the jam has thickened, about 15 minutes. It will continue to thicken as it cools.
- Ladle the hot jam into the jars, leaving ¼ inch of headspace. Remove any air bubbles. Wipe the rims clean and seal tightly with the lids.
- Put the jars in a boiling-water bath for 10 minutes. Make sure the jars are covered in water. The sealed jars can be stored in a cool, dark place for up to 1 year. If a sealed has failed, store the jar in the refrigerator for up to 1 month. Makes 6 half-pint jars.
