- 700 grams granulated sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest (optional, for extra freshness)
- 1 teaspoon vanilla extract (optional)
- A small pinch of salt

Instructions
Step 1: Prepare the Strawberries
Wash the strawberries thoroughly under cool running water. Remove the green stems and leaves, then cut larger strawberries into smaller pieces. Smaller pieces cook more evenly and release their natural juices faster.
Place the prepared strawberries into a large bowl. If you prefer a smoother jam, you can mash the strawberries slightly before cooking. For a chunkier homemade style, leave some pieces larger so the final jam contains visible fruit pieces.
Step 2: Combine Ingredients
Transfer the strawberries into a large cooking pot. Add the sugar, lemon juice, lemon zest, and salt. Stir everything together until the strawberries are evenly coated.
Allow the mixture to rest for 10–15 minutes before cooking. This step helps the strawberries release their juices and allows the sugar to begin dissolving.
Step 3: Cook the Strawberry Mixture
Place the pot over medium heat. The cooking intensity should be moderate—not too high—because excessive heat can burn the sugar and damage the fresh strawberry flavor.
Cook the strawberries for about 10 minutes, stirring frequently. The mixture will become more liquid as the fruit releases juice.
Once the strawberries begin to boil gently, reduce the heat slightly to medium-low. Continue cooking for 25–35 minutes. Stir every few minutes to prevent sticking.
During cooking, foam may appear on the surface. You can remove the foam with a spoon if you want a clearer-looking jam, although it is safe to leave it.
Step 4: Check the Jam Consistency
To test whether the jam is ready, place a small plate in the freezer for a few minutes. Drop a small amount of hot jam onto the cold plate and wait for a few seconds. Push the jam gently with your finger. If it wrinkles slightly and does not run quickly, the jam is ready.
If the jam is too thin, continue cooking for another 5–10 minutes over low heat. Remember that jam thickens more as it cools.
Step 5: Add Final Flavor
Remove the pot from heat. Stir in vanilla extract if desired. Allow the jam to rest for 5 minutes before transferring it into jars.
The finished jam should have a rich strawberry aroma, bright red color, and a thick but spreadable texture.
Step 6: Store the Jam
Carefully pour the warm jam into clean, sterilized glass jars. Leave a small amount of space at the top before sealing the jars.
Allow the jars to cool completely at room temperature. Store homemade strawberry jam in the refrigerator and use within 3–4 weeks.
For longer storage, properly sealed and processed jars can last several months in a cool, dark place. Always check for unusual smells, mold, or changes in appearance before consuming.
Cooking Intensities and Timing Guide
- Strawberry preparation: 15 minutes, no heat required
- Initial cooking stage: 10 minutes on medium heat
- Simmering stage: 25–35 minutes on medium-low heat
- Final thickening stage: 5–10 minutes if needed on low heat
- Cooling stage: 1–2 hours at room temperature
Maintaining the correct heat intensity is important. High heat may cause the sugar to caramelize too quickly and create a burnt taste. Low and steady cooking produces a deeper strawberry flavor and a better texture.
Tips for Perfect Homemade Strawberry Jam
- Use fresh, ripe strawberries for the best flavor and natural sweetness.
- Avoid using damaged or overripe fruit because it can affect the taste and storage life.
- Stir regularly while cooking to prevent the jam from sticking to the bottom of the pot.
- Do not overcook the jam because it may become too thick and lose its fresh fruit flavor.
- Use sterilized jars to keep the jam fresh for longer.
- Adjust the sugar slightly depending on how sweet your strawberries are.
- Lemon juice is important because it balances sweetness and helps create the classic jam texture.
