Homemade Blueberry Mojito Jam: A Zesty Summer Twist with Mint and Lime
Imagine the vibrant burst of fresh blueberries, perfectly complemented by the bright, zesty notes of lime and the cool, aromatic whisper of mint. This isn’t just any jam; this is Blueberry Mojito Jam—a truly exhilarating summer twist on traditional homemade blueberry preserves. It’s an instant classic that captures the essence of a refreshing mojito cocktail in a sweet, spreadable form. Get ready to elevate your breakfast, desserts, and even your cocktails with this delightful creation.
Why Blueberry Mojito Jam is Your New Summer Obsession
While classic blueberry jam is undeniably delicious and a staple in many pantries (we certainly went through our share last year!), the addition of fresh mint and tangy lime transforms it into something truly extraordinary. This flavor profile isn’t just an improvement; it’s an adventure for your taste buds. The lime cuts through the sweetness of the blueberries, adding a beautiful tartness, while the mint provides a cool, herbaceous finish that brightens every spoonful. It’s like bottling sunshine with a hint of garden freshness. Trust us, these jars won’t linger on your shelves for long!
The Simple Joy of Homemade Preserves
There’s an undeniable satisfaction that comes with making your own jam. From selecting the freshest ingredients to watching the fruit transform into a glossy, jewel-toned preserve, the process is incredibly rewarding. Lately, I’ve been on a bit of a jam-making spree, revisiting beloved recipes like my strawberry and rose water jam and exploring exciting new combinations. This blueberry mojito jam recipe, inspired by a canning magazine, quickly became a new favorite because of its wonderfully fresh, bright, and surprisingly complex flavor.
Achieving the Perfect Jam Consistency
The texture of your jam is a matter of personal preference. I often prefer my jam a little softer, less rigidly set, making it wonderfully spreadable and versatile. This looser consistency is absolutely divine as a topping for fluffy pancakes, a generous swirl into creamy yogurt, a vibrant accompaniment to ice cream, or even as an intriguing addition to your favorite cocktails – imagine a mojito jam-infused spritzer! If you prefer a thicker, more traditional gelled jam, simply cook it a bit longer. The key is to find the consistency that you enjoy most, and the flexibility of this recipe allows for just that.
Mastering Jam Making Without Added Pectin
Many modern jam recipes rely on commercial pectin to achieve a quick and reliable set. However, a secret to truly delicious, old-fashioned jam lies in understanding and utilizing the pectin that naturally occurs within fruits. Pectin is a soluble fiber found in the cell walls of fruits, particularly concentrated in their skins, seeds, and pulp. When heated with sugar and acid (like the lime juice in our recipe), pectin forms a gel, giving jam its characteristic texture.
While extracting natural pectin requires a bit more cooking time, the result is often a jam with a more intense, pure fruit flavor, as you’re not masking it with added gelling agents. It’s a method that allows the fruit’s true essence to shine through, creating a superior final product that tastes homemade in the best possible way.
Understanding Fruit Pectin Levels
Not all fruits are created equal when it comes to pectin content. Some fruits are naturally high in pectin, making them ideal for setting jams without additional help. These include:
- High Pectin Fruits: Apples (especially Granny Smith), cranberries, lemons, limes, quince, sour cherries, some plums, and gooseberries.
Other fruits have a lower pectin content, which can make achieving a firm set more challenging on their own. For these fruits, you might consider:
- Low Pectin Fruits: Apricots, sweet cherries, peaches, pears, rhubarb, and most berries (including blueberries!).
For low-pectin fruits like blueberries, adding a high-pectin fruit (such as lemon or lime juice and zest, as we do in this mojito jam recipe) or cooking for a longer duration is essential. The lime juice not only adds fantastic flavor but also provides the necessary acidity to help the natural pectin in the blueberries to gel.
How to Test the Jelling Point for Perfect Jam
Knowing when your jam has reached its “jelling point” is crucial for the right consistency. There are a few reliable methods to test this:
- The Cold Plate Test: Place a small plate in the freezer before you start cooking. When you think the jam is ready, spoon a small amount onto the cold plate. Let it sit for 30-60 seconds, then push it with your finger. If it wrinkles and forms a skin, it’s ready. If it’s still runny, cook for a few more minutes and retest.
- The Spoon Test (or Sheeting Test): Dip a cold spoon into the hot jam and lift it horizontally, allowing the jam to drip off. If the jam forms two drops that merge into a “sheet” or a single drop that hangs off the spoon before falling, it’s ready. If it drips off quickly in individual drops, it needs more time.
- The Temperature Test: Using a candy thermometer, cook the jam until it reaches 220°F (104°C) at sea level. This temperature indicates that enough water has evaporated for the pectin to gel. Adjust for altitude (subtract 2°F for every 1000 feet above sea level).
Combining these methods gives you the best chance for perfect results every time. Remember, the cooking time for jam without pectin can vary, typically ranging from 30-45 minutes or even longer, depending on the fruit and the desired thickness. Patience is key!
Blueberry Mojito Jam

Ingredients
- 2 lbs fresh blueberries (900 grams)
- 2 ½ cups granulated sugar (500 grams)
- Zest of 3 limes
- ¼ cup fresh lime juice (60 ml, from 2-3 limes)
- 4 sprigs fresh mint , bundled together with cotton string
Instructions
-
In a large heavy-bottom pot, combine the blueberries, sugar, lime zest and lime juice. Set over medium heat. Bring to a boil, stirring occasionally to dissolve sugar.
-
Add the bundle of mint to the jam. Let jam simmer until thickened and reduced, about 30-45 minutes. Stir frequently and skim foam from surface as it cooks.
-
Test the jelling point by using a cool spoon to scoop up some of the jam. Tip the spoon so that it runs back into the pot. If it all runs off, it needs more time. If it forms drops that hang before falling into the pot, then it is ready. [See this cheat sheet for more information on how to tell if your jam is done|http://www.portlandpreserve.com/TestingTheJellyPoint.pdf].
-
Remove the mint bundle and discard (see Note). Ladle jam into sterilized jars. Top with a lid and screw on with a ring. Process jars in a water bath for 10 minutes (15 minutes for 5,000+ ft elevation). Remove from water bath and let cool.
-
Check that lids have sealed by pressing down into the center of each one. It should not move. Store jam in a cool dry place like a pantry and consume within 1 year.

Tips for Successful Water Bath Canning
Once your delicious Blueberry Mojito Jam is ready, proper canning techniques are essential to ensure its safety and longevity. Water bath canning is a simple and effective method for high-acid foods like jam:
- Sterilize Your Jars: Always start with clean, sterilized jars and lids. You can sterilize them by boiling in water for 10 minutes, running them through a dishwasher’s sanitizing cycle, or heating them in an oven (jars only).
- Fill Jars Properly: Ladle hot jam into hot sterilized jars, leaving about ¼ inch (0.6 cm) headspace. Wipe the rims clean to ensure a good seal. Place new lids and rings on the jars, tightening finger-tight.
- Process in Water Bath: Carefully place jars into a boiling water canner, ensuring they are fully submerged by at least an inch of water. Bring the water back to a rolling boil and process for the recommended time (typically 10 minutes for half-pint jars at sea level; adjust for higher altitudes).
- Cool and Check Seals: After processing, remove jars and place them on a towel to cool completely for 12-24 hours. You should hear a “pop” as the lids seal. To check the seal, press the center of the lid; if it doesn’t flex, it’s sealed. Unsealed jars should be refrigerated and consumed within a few weeks.
Following these steps will ensure your homemade blueberry mojito jam is safely preserved and ready to enjoy for months to come. Store sealed jars in a cool, dark pantry and savor the taste of summer even in the depths of winter.
