Ingredients
To create this delightful strawberry jam, gather the following ingredients:
Fresh Ingredients
- 2 pounds of ripe strawberries, hulled and halved

- 1/4 cup of pectin (preferably powdered)
- 3 cups of granulated sugar
- 1/2 teaspoon of unsalted butter (for reducing foam)
How to Make Strawberry Jam (Step-by-Step)
Creating your own strawberry jam is a delightful experience that preserves the taste of summer.
Step 1: Prep Your Strawberries
Start by washing the strawberries thoroughly under cool water. Once they’re clean, hull and halve them. As I cut into these vibrant red jewels, I’m transported to my favorite farmer’s market in Brooklyn, where their intoxicating fragrance fills the air.
Step 2: Cook the Strawberries
In your heavy-bottomed pot, combine the strawberries and lemon juice. Heat over medium until the mixture begins to bubble. Here, I like to mash the strawberries a little with my wooden spoon to release their juices, creating a bright red syrup. This should take about 5-7 minutes, and you’ll want to whisk until the mixture is bubbling and glossy.
Step 3: Add Pectin and Sugar
Stir in the pectin and allow the mixture to come back to a rolling boil. This is where the magic begins! Once boiling, carefully add all the sugar, stirring constantly. The nutty aroma of the dissolving sugar fills the kitchen, reminding me of my favorite dessert shops.
Step 4: Boil Until Set
Bring the mixture back to a rapid boil for exactly one minute, stirring continuously. If you have a candy thermometer, aim for about 220°F, which is where it will gel perfectly. You’ll notice the color deepening and the consistency thickening; it’s a beautiful sight!
Step 5: Test for Doneness
To ensure your jam is ready, I like to do the “plate test”: drop a spoonful onto a cold plate and refrigerate for a minute. When you run your finger through it, it should hold its shape.
Step 6: Remove Foam
Before transferring to jars, add a touch of unsalted butter to reduce any foam that has formed on top. It comes back to a gentle bubble again; the aroma is heavenly.
Step 7: Jar It Up
Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace. Wipe the rims with a clean cloth to ensure a good seal, then place the lids on tightly.
Step 8: Process the Jars (Optional)
If you want a longer shelf life, process your jars in a boiling water bath for about 10 minutes. Otherwise, allow them to cool completely on a kitchen towel or wire rack.

Common Mistakes to Avoid
- Using overripe strawberries: Ensure your strawberries are ripe but not overly soft or mushy, as they will alter the texture and flavor of your jam.
- Skipping the lemon juice: This is crucial for balancing the sweetness and ensuring proper gelling—don’t leave it out!
- Not testing for doneness: Rushing through the boiling process can leave you with runny jam. Always perform the plate or temperature test.
Tips and Tricks for Success
- For a fun twist, try adding a few basil leaves or a splash of vanilla extract for a unique flavor profile.
- Label your jars with the date and consider including a sweet message if you’re giving them as gifts.
- Strawberry jam pairs beautifully with cheeses, so think about serving it alongside a cheese platter during your holiday gatherings.
Variations
- Substitute raspberries or blueberries for part of the strawberries for a mixed berry jam.
- Add a tablespoon of balsamic vinegar for a savory twist.
- Incorporate a pinch of cinnamon or nutmeg for a warm flavor.
How to Serve
- Spread on toast or bagels for a delightful breakfast.
- Use as a filling for pastries or cakes.
- Serve alongside a cheese platter for an elegant appetizer.
