Jalapeño Strawberry Jam: Sweet Heat in a Jar

The first time I made Jalapeño Strawberry Jam, I was honestly a bit nervous about how it would turn out. Would the peppers overwhelm the sweet strawberries? Would my family think I’d lost my mind? But that initial spoonful was a revelation – the perfect marriage of sweet summer berries with a warm, gentle heat that lingered just long enough to make you crave another taste.

Now it’s become my signature homemade gift, and friends start asking when “jam season” is coming months in advance!

This unique preserve transforms everyday dishes into something special. Spread it on a buttery biscuit, spoon it over cream cheese with crackers, or use it to glaze grilled chicken – the possibilities are endless. What I love most is watching people’s expressions change from skepticism to delight when they taste this unexpected combination for the first time.

• 1 package (1.75 oz) regular powdered fruit pectin

How to Make Jalapeño Strawberry Jam

Prepare Your Equipment

1. Wash jars, lids, and bands in hot, soapy water. Rinse well.
2. Keep jars warm until ready to use – either via dishwasher or a pot of simmering water.
3. Set up a water bath canner if planning to can the jam. Fill halfway with water and bring to a simmer.
4. Place a small plate in the freezer for testing jam set later.

Prepare the Fruit and Peppers

1. Wash and hull strawberries. Chop into desired size – chunky or fine.
2. Wear gloves and finely dice jalapeños. Remove all seeds for mild jam, keep some for more heat.
3. Combine 4 cups of chopped strawberries, diced jalapeños, and lemon juice in a heavy-bottomed pot.

Cook the Jam

1. Stir in the powdered pectin and butter (if using).
2. Bring to a full rolling boil over high heat, stirring constantly.
3. Add all the sugar at once. Stir to dissolve and return to a rolling boil.
4. Boil hard for exactly 1 minute, then remove from heat.
5. Skim off foam, stir in vanilla extract if desired.
6. Use the chilled plate to test for set – place a spoonful on it, chill for 1 min, and push. If it wrinkles, it’s ready.

Can the Jam

1. Ladle hot jam into prepared jars, leaving 1/4-inch headspace.
2. Wipe rims clean. Apply lids and bands, tightening to fingertip-tight.
3. Process jars in a boiling water bath for 10 minutes (adjust for altitude).
4. Let jars rest on a towel-lined surface for 24 hours without touching.
5. Check seals – lids should not flex. Label with name and date.

FAQs About Jalapeño Strawberry Jam

Can I adjust the heat level?

Yes! Use fewer jalapeños and remove all seeds for milder jam. For more kick, include more seeds or add a hotter pepper like serrano or habanero.

Can I use frozen strawberries?

Absolutely. Thaw completely and drain before measuring. Fresh berries offer best flavor, but frozen are great out of season.

Why didn’t my jam set properly?

This may be due to not using enough pectin, skipping the exact sugar measurement, or not boiling long enough. Reboil with extra pectin if needed.

Can I reduce the sugar?

Only if using low- or no-sugar pectin. Standard pectin relies on sugar for proper set.

Can I use other berries?

Yes! Try raspberry, blackberry, or a mix. Just keep the total fruit amount the same.
