Pepper jelly has one job: sweet first, heat second, both in the same spoonful. Pineapple turns out to be the perfect fruit for it — brighter and more tropical than the usual bell-pepper base, with enough acidity to keep the jelly tasting fresh instead of candy-sweet.

This recipe uses canned crushed pineapple, and that is deliberate. Its juice content is consistent from tin to tin, which matters when you want a jelly that sets the same way every single batch — fresh pineapples vary too much in juiciness for reliable canning results.

The peppers are a two-part team: red bell pepper for color and sweet pepper flavor, jalapeños for a clean, front-of-the-tongue heat that builds gently and lets go. Three jalapeños lands it at a friendly medium; the tips below explain how to move the dial either way.

Five half-pint jars: one for the cheese board this weekend, the rest for gifts and glazes all season.

Why You’ll Love This Recipe

The flavor balance is built in, not hoped for. Pineapple’s acidity cuts the sugar, the cider vinegar sharpens everything, and the peppers arrive as warmth rather than a dare — this is a jelly people go back for, poured over cream cheese with crackers.

It is a genuine pantry recipe. Processed jars keep for a year in a cool cupboard, which makes this a smart way to stock homemade gifts long before you need them — the same satisfaction as putting up our peach moonshine, minus the wait to enjoy it.

Ingredients

Gloves on before you touch the jalapeños — pepper oils on your fingers have a way of finding your eyes an hour later:

2 cans (20 oz / 567 g each) crushed pineapple in juice, undrained
½ cup finely minced red bell pepper (about 1 medium pepper)
⅓ cup finely minced jalapeño peppers (about 3 peppers; keep seeds for more heat, remove for milder)
¼ cup apple cider vinegar (5% acidity)
1 package (1.75 oz / 49 g) regular powdered fruit pectin
½ teaspoon unsalted butter (optional, reduces foaming)
4½ cups (900 g) granulated sugar, measured and ready

You will also need: five half-pint (8 oz) canning jars with new lids and bands, a boiling-water canner with rack, jar lifter, canning funnel, and a ladle.

How to Make It

Prepare the canner and jars: Fill the canner about two-thirds with water and bring it toward a simmer. Wash the jars in hot soapy water, rinse, and keep them hot in the simmering canner water (or a 200°F / 95°C oven) until filling — hot jars plus hot jelly prevents cracking. Place the flat lids in a small saucepan of hot (not boiling) water.
Combine the base: In a large, heavy pot (at least 6-quart — jelly foams high), stir together the crushed pineapple with its juice, minced red pepper, minced jalapeño, cider vinegar, pectin, and the butter if using.
First boil: Bring the mixture to a full rolling boil over high heat, stirring constantly — a rolling boil is one that does not stop bubbling when stirred. This activates the pectin.
Add the sugar: Pour in all the sugar at once and stir to dissolve. Return to a full rolling boil and boil hard for exactly 1 minute, stirring constantly. Remove from the heat and skim off any foam with a metal spoon.
Rest and stir: Let the pot stand 4 to 5 minutes, stirring twice. This short rest thickens the jelly just enough that the pepper pieces stay suspended instead of floating to the tops of the jars.
Fill the jars: Ladle the hot jelly into the hot jars through the funnel, leaving ¼-inch headspace — measure it; headspace is what allows a vacuum seal to form. Wipe each rim with a clean, damp cloth, center a lid, and screw the band on fingertip-tight, snug but not forced.
Process: Lower the jars onto the canner rack, making sure they are covered by at least 1 inch of water. Cover, bring to a full boil, and process half-pints for 10 minutes at sea level (add 5 minutes if you live between 1,001 and 6,000 feet). Start timing only once the water is fully boiling.
Cool and check: Turn off the heat, remove the lid, and wait 5 minutes before lifting the jars out with the jar lifter. Set them upright on a towel, undisturbed, for 12 to 24 hours. Then press the center of each lid — it should be firm and slightly concave, with no flex. Label and date the sealed jars.

Cooking Tips / Variations

No-canning refrigerator version: skip the canner entirely. Ladle the finished jelly into clean jars or containers, cool, and refrigerate. It keeps up to 3 weeks in the fridge, or freeze it for up to 3 months in freezer-safe containers with ½-inch headspace for expansion. Same jelly, shorter commitment.

Heat control lives in the jalapeños. For mild: use 2 peppers, seeds and membranes fully removed. For properly hot: keep all the seeds, or swap one jalapeño for a habanero (minced fine, gloves absolutely on) — the habanero’s fruity flavor pairs beautifully with pineapple.

If peppers float despite the rest-and-stir step, your mince was too coarse or the jelly went into jars too hot and thin. Next batch, mince finer and rest the full 5 minutes; this batch is still perfectly good — just stir each jar after opening.

A spoonful melted and brushed over burgers in the last minute of grilling is quietly excellent — if burgers are on the menu, our homemade burger recipe gives you the patties to put under it.

Serving or Storage Tips

The classic serve: pour a jar over a block of cream cheese, surround with sturdy crackers, and watch it disappear. Sharp cheddar, aged gouda, and soft goat cheese all suit the sweet heat just as well.

Sealed, processed jars store in a cool, dark cupboard for up to 1 year. Refrigerate after opening and use within 1 month. Any jar whose lid flexes, bulges, or never sealed goes straight to the refrigerator and gets used within 3 weeks, like the fridge version.

Melt ¼ cup of jelly with 1 teaspoon of water for an instant glaze — brush it over grilled shrimp, chicken wings, or a ham steak in the final minutes of cooking, and serve the extra warm at the table.

Conclusion

Pineapple and peppers were made for each other, and this jelly is the proof you can seal in a jar: tropical, golden, sweet up front, warm at the finish.

Follow the canning steps exactly as written — sterilized hot jars, ¼-inch headspace, full processing time — and the recipe rewards you with a shelf of jars you can trust for a year.
