Ingredients for apple and blueberry jam recipe uk

UK pantry staples and seasonal fruit—nothing fancy, just perfect jam.

UK supermarkets like Tesco and Sainsbury's stock Braeburn apples—ideal for their tartness. Blueberries? Frozen works just as well (no need to thaw), and Waitrose often has great organic options. Sugar-wise, caster dissolves faster, but white granulated is fine. The jars? 8oz sterilized glass are standard—buy a set from Amazon UK or your local kitchen store. Look for jars with wide mouths for easy filling.

No Granny Smith apples? Cox's Orange Pippin works beautifully—just add an extra 0.25 cup sugar to balance tartness. Short on lemon? Lemon juice concentrate (diluted 1:1) saves money. The cinnamon is optional but adds warmth—Penzeys or Waitrose bulk bins have good quality. No pectin? Extra 1 tbsp lemon juice helps thicken, or just leave it—it'll still set nicely. The jam sugar? Only needed if you want a firmer jam, but the recipe works without it.

Sterilize jars by baking at 250°F (120°C) for 15 minutes—no boiling water needed. Once cooled, fill to the rim and seal with lids. Stored in a cool, dark pantry, this jam keeps for up to 12 months. I always label jars with the date—gifting season is peak jam time. Freeze extras if you're not using them within 6 months.

Step-by-step instructions for apple and blueberry jam

Here's how to make this vibrant, long-lasting jam that'll keep beautifully in your cupboard.

Start by sterilizing your jam jars. Place them upside down in a 200°F oven for 10 minutes while you prepare the fruit. This ensures clean jars that'll seal properly. Meanwhile, peel, core, and chop the 2 lb Apples (Granny Smith or Braeburn) into small, even pieces—about ¼-inch cubes. I like to use a sharp knife for this step to keep the fruit uniform.

In a separate bowl, gently rinse the 1.5 lb Blueberries if using fresh ones, then drain well. If using frozen blueberries, no need to thaw—just drain them completely. The fruit should be dry before cooking to prevent a watery jam. You'll notice the blueberries will stain your hands slightly—that's normal and part of the charm!

In a large, heavy-bottomed saucepan, combine the chopped apples, blueberries, 2 cups Granulated Sugar, 2 tbsp Lemon Juice, 1 tsp Fresh Lemon Zest, and 0.5 cup Water. Stir gently to combine—no need to mash the fruit. Place the pan over medium-high heat and bring to a gentle boil, stirring occasionally to prevent sticking.

Once boiling, reduce the heat to medium-low and let it simmer for 20 minutes, stirring every 5 minutes. You'll see the fruit soften and the juices start to release. After 20 minutes, taste the mixture—it should be sweet but still have a bit of tartness from the apples. If it needs more sweetness, add 1 cup Jam Sugar (or plain sugar) now and stir until dissolved. This extra sugar helps create that perfect set for long shelf life.

After the initial 20 minutes, increase the heat back to medium-high and bring the mixture to a rolling boil. Let it boil vigorously for 5-7 minutes, stirring constantly to prevent burning. This boiling time is crucial for developing the jam's texture and flavor. You'll notice the mixture will thicken noticeably as it cooks.

To test if the jam is ready, perform the plate test: spoon a small amount onto a chilled plate and let it sit for 1 minute. If it wrinkles slightly when you push it with your finger, it's ready. If not, boil for another 2-3 minutes and test again. I've found this test is more reliable than timing alone—every stove heats differently!

While the jam is still hot, quickly ladle it into your sterilized jars, leaving about ¼-inch headspace at the top. Wipe the jar rims with a clean, damp cloth to ensure a good seal. Sprinkle 1 tbsp Caster Sugar over the top of each jar—this helps create an airtight seal and prevents mold growth.

Place lids on the jars and tighten the rings until they're fingertip-tight (not too tight, or they won't seal properly). Process the jars in a water bath for 10 minutes—this sterilizes the sealed jars and ensures they'll keep for months. Remove the jars and let them cool completely on a towel before checking the seals. Properly sealed jars should pop when pressed in the center and won't make a "ping" sound when the lid is pressed.

Once cooled and sealed, store your jam in a cool, dark place. This beautiful apple and blueberry combination will keep for up to 12 months—perfect for gifting or enjoying throughout the year. The colors will be stunning: deep purple from the blueberries and bright green from the Granny Smith apples.

Use your jam on toast, scones, or yogurt. The balance of sweet and tart flavors makes it versatile for both breakfast and dessert applications. If you're feeling adventurous, try it in savory dishes like glazed ham—trust me, the combination is unexpected but fantastic!

Pro cooking tips for this dish

Heat Control Secrets

Jam-making is all about gentle heat control—too high, and you risk burning the fruit; too low, and it won’t set properly. I start with medium-high heat to bring the mixture to a boil, then immediately reduce to medium-low for the 20-minute simmer. This prevents scorching while allowing the fruit to break down naturally. A heavy-bottomed saucepan (like my trusty Le Creuset) is worth the investment—it distributes heat evenly and prevents hot spots that can burn your jam. 🌡️

When you reach the final boil, stir constantly to avoid sticking. If your stove runs hot, reduce the heat slightly—every kitchen is different. I’ve learned this the hard way: once, I walked away for just a minute, and my jam turned into a sad, burnt syrup. Now, I set a timer and keep my eye on it!

Pectin Hacks

This recipe skips commercial pectin, but if you want a firmer set, add 1 tbsp liquid pectin during the final boil. For a natural alternative, I’ve found that extra lemon juice (1 tbsp) or 1 tsp cornstarch (mixed with water) works surprisingly well. The key is adding it after the initial simmer but before the final boil—this ensures it activates properly. 🧪

Pro tip: If your jam isn’t setting after boiling for 5-7 minutes, don’t panic. Simmer uncovered for another 2-3 minutes—the sugar will concentrate as the water evaporates, and the jam will thicken. Just be patient; rushing it leads to grainy texture or a runny mess.

Fruit Prep Matters

Chopping apples into even ¼-inch cubes ensures consistent cooking. Larger pieces stay crunchy, while smaller ones turn mushy. I use a sharp chef’s knife (my Wüsthof) for clean cuts. For blueberries, draining them thoroughly is critical—wet fruit releases too much liquid, resulting in a watery jam. Pat them dry with a paper towel if needed. 🍎

If using frozen blueberries, no thawing required—just drain them well. The cold fruit will lower the initial temperature of the mixture, so you might need an extra 1-2 minutes of simmering to reach the same consistency. Fresh blueberries? Rinse them gently in a colander to remove dirt, but avoid soaking—they’ll absorb water and dilute the jam.

Jam Test Tricks

The plate test is foolproof: spoon a small amount of jam onto a chilled plate and let it sit for 1 minute. Push it gently with your finger—if it wrinkles slightly, it’s ready. If it slides around like syrup, boil for another 2 minutes and test again. I keep a small plate in my freezer just for this purpose. ✨

Another trick? The sheet test: spread a thin layer of jam on a piece of parchment paper. If it holds its shape and doesn’t drip when you lift the paper, it’s done. This works best for lighter jams like this one, where you want to preserve some fruit texture.

Sterilization Shortcuts

Sterilizing jars doesn’t have to mean boiling them in water for 10 minutes—I’ve found that baking them upside down in a 200°F (120°C) oven for 10 minutes works just as well and saves on energy. After sterilizing, let the jars cool slightly before filling to prevent thermal shock (which can cause cracks). 🍶

For lids, I pop them in the oven too, but if you’re short on time, just boil them in a small pot of water for 5 minutes. The key is clean jars and lids—any dirt or residue can prevent a proper seal. I also wipe the jar rims with a damp cloth right before filling to remove any sugar residue that might interfere with sealing.
