This vibrant jalapeño strawberry jam brings together the sweet juiciness of fresh summer strawberries with a gentle kick of heat from jalapeños. It's the perfect balance of sweet and spicy that elevates everything from your morning toast to sophisticated cheese boards.
I created this recipe when my garden produced an abundance of both strawberries and jalapeños one summer. What started as an experiment has become my signature preserve that friends and family request every holiday season.
Ingredients
- Fresh strawberries: The star ingredient providing natural sweetness and bright color, choose ripe berries with deep red color for best flavor
- Jalapeño peppers: Adding just the right amount of heat that complements the sweetness of strawberries, select firm peppers with glossy skin
- Granulated sugar: Preserves the fruit while enhancing the natural sweetness of strawberries
- Lemon juice: Acts as a natural preservative and adds necessary acidity for proper setting
- Fruit pectin: Ensures your jam sets properly with the perfect consistency
- Water: Helps create the right consistency during cooking
Step-by-Step Instructions
- Prepare the fruit:
- Thoroughly wash, hull, and chop strawberries into small pieces for even cooking. For the jalapeños, remove the seeds and membranes if you prefer milder heat, or leave some in for more spice. Finely chop the peppers to distribute the heat evenly throughout the jam. The size of your chop determines the final texture, so aim for uniform pieces about 1/4 inch in size.
- Create the base:
- Combine the prepared strawberries, chopped jalapeños, and water in a large saucepan. Use a heavy bottomed pan to prevent scorching. Bring the mixture to a boil over medium heat, then reduce to a simmer for 5-10 minutes. This preliminary cooking breaks down the strawberries and allows the jalapeño flavor to infuse throughout. Stir occasionally to prevent sticking.
- Add sweetness and acidity:
- Once your fruit has softened, stir in the sugar and lemon juice. The mixture will become more liquid as the sugar dissolves. Continue stirring constantly to prevent burning, especially as the sugar can quickly caramelize on the bottom of the pan. The lemon juice brightens the flavor and helps with preservation.
- Incorporate the pectin:
- Gradually sprinkle the pectin into the fruit mixture while stirring continuously to prevent clumping. This step requires attention to detail for proper setting. Make sure all pectin is fully dissolved before proceeding to the next step.
- Achieve the set:
- Bring your mixture back to a rolling boil and maintain it for 5-7 minutes, stirring frequently. You'll notice the consistency starting to thicken. To test if it's ready, place a small spoonful on a cold plate and refrigerate for one minute. If it wrinkles when pushed with your finger, it's set.
- Jar and preserve:
- Working quickly while the jam is hot, carefully ladle it into sterilized jars, leaving 1/4 inch headspace. Wipe the rims clean, apply lids and bands, and either process in a water bath for longer storage or refrigerate for immediate use.

My favorite part of this recipe is watching people's reactions when they taste it for the first time. That moment of surprise when the sweetness hits first, followed by the gentle warmth of the peppers always brings a smile. My grandmother, who was skeptical about the combination at first, now requests a jar for her morning biscuits every Christmas.
Serving Suggestions
This versatile jam goes far beyond the typical toast and biscuits. Try it spooned over cream cheese or brie with crackers for an impressive appetizer that takes seconds to assemble. The contrast between the creamy cheese and sweet-spicy jam creates a perfect flavor symphony that your guests will rave about.
Storage Tips
For everyday use, store your jam in the refrigerator where it will maintain peak flavor and quality for up to 3 weeks. The high sugar content acts as a preservative, but refrigeration ensures food safety and preserves the vibrant color.
Flavor Variations
The basic recipe is wonderfully versatile and can be adapted to suit your taste preferences or what's available seasonally. For a smokier profile, replace the jalapeños with chipotle peppers – just use about half the amount as they pack more heat. The smokiness pairs remarkably well with the sweet strawberries.

The perfect balance of sweet and spicy, this jam will quickly become a favorite in your household.
Frequently Asked Questions
- → How long does homemade jalapeño strawberry jam last?
When properly sealed in sterilized jars using a hot water bath, jalapeño strawberry jam can last up to 12 months in a cool, dark place. Once opened, store in the refrigerator and use within 3-4 weeks. If you skip the canning process, the jam should be refrigerated immediately and consumed within 2-3 weeks.
- → How can I adjust the spice level in this jam?
The heat level can be easily customized by adjusting the number of jalapeños used and whether you include the seeds and membranes. For mild heat, use one seeded jalapeño. For medium heat, use two seeded jalapeños. For spicy jam, include some or all of the seeds and membranes, which contain most of the capsaicin (the compound that makes peppers hot).
- → What can I serve with jalapeño strawberry jam?
This versatile preserve shines on cheese boards alongside cream cheese, brie, or goat cheese. It makes a fantastic spread for breakfast toast, English muffins, or scones. Try it as a glaze for grilled chicken or pork, stirred into yogurt, or as a topping for vanilla ice cream for a sweet-heat contrast.
- → Can I use frozen strawberries instead of fresh?
Yes, frozen strawberries can be substituted for fresh. Thaw them completely and drain excess liquid before using. You may need to reduce the water slightly in the recipe since frozen berries typically release more moisture when cooking.
- → What other berries work well with jalapeños?
Several berries pair wonderfully with jalapeños. Try raspberries for a more intense berry flavor, blackberries for earthiness, or blueberries for a milder profile. You can even create a mixed berry version using a combination of strawberries, raspberries, and blackberries while maintaining the same total fruit quantity.
- → Do I need to use pectin in this jam?
Pectin helps achieve a proper jam consistency and is recommended, especially for strawberries which are naturally lower in pectin than some other fruits. Without pectin, you would need to cook the mixture significantly longer, which can affect the fresh flavor and bright color. If you prefer to skip commercial pectin, you could add apple (high in natural pectin) or increase the lemon juice significantly.
