Zesty Blueberry Lime Marmalade Recipe for Homemade Jars

Blueberry lime marmalade turns the classic citrus-and-berry pairing into a true marmalade, with thin ribbons of lime peel throughout. The lime adds a bright, slightly tropical aroma that differs from traditional lemon marmalades.

Blueberries and lime make a vibrant pairing; the lime’s aromatic peel complements the sweet, deep purple of the berries. I tested both lemon and lime versions side by side and enjoyed them for different reasons—lime brings a brighter, more tropical note that pairs especially well with blueberries.

Because limes have more pith relative to their size than lemons, plan on about 8 to 10 medium limes per pound. The additional pith is useful here: it contains natural pectin that helps the marmalade set.

This recipe uses no added pectin. An overnight soak softens the peel and reduces bitterness while a long simmer extracts natural pectin from the citrus. It’s the same traditional technique used in many classic marmalades and results in a lovely, old-fashioned set.

Notes from My Kitchen

My husband prefers lime, so after making a lemon version I developed this lime adaptation. The flavor is distinctly brighter and more aromatic. The contrast of deep purple jam dotted with green-tinged lime peel is attractive, and this small-batch recipe produces about three half-pints—perfect for trying a new flavor.

Ingredients

This is a traditional no-pectin marmalade that depends on the natural pectin in citrus peel. An overnight soak softens the peel and releases pectin, while the blueberries contribute color, sweetness, and additional pectin.

• Limes: Use limes that feel heavy for their size with smooth skins; Persian limes are convenient, while Key limes work if you don’t mind using more fruit. Organic or well-scrubbed conventional limes are fine since the peel is used.
• Blueberries: Fresh or frozen blueberries both work; frozen berries break down a bit faster. Wild blueberries offer a more intense flavor if available.
• Water: Used for the overnight soak and again for simmering.
• Granulated Sugar: Provides sweetness, aids gel formation with natural pectin, and preserves the marmalade. I don’t recommend reducing the sugar significantly for a no-pectin marmalade because the sugar-to-fruit ratio contributes to the set.

Step by Step Instructions

This is a two-day process. Day one is the citrus soak; day two is cooking and canning. Don’t set up your water bath canner until day two when the marmalade is ready to process.

Prepare and Soak the Limes

Wash and scrub limes with hot water. Quarter each lime lengthwise, then slice each quarter crosswise into very thin slices (about 1/8 inch). Remove and discard seeds. Place the sliced limes in a large bowl, cover with water, and soak overnight (at least 8 hours) at room temperature to soften the peel and reduce bitterness.

Simmer the Citrus

Drain and discard the soaking water. Put the lime slices into a large, heavy saucepan with 2 cups fresh water. Bring to a boil, then reduce heat and simmer 10 to 15 minutes, stirring occasionally, until the peel is very tender.

Add Blueberries and Sugar

Add the blueberries and granulated sugar to the pan, stirring until the sugar dissolves. Increase heat and bring to a full rolling boil, stirring frequently to avoid scorching.

Cook to Gel Point

Continue boiling until the marmalade reaches the gel point (220°F at sea level) or passes the cold plate test. This usually takes 8 to 10 minutes of vigorous boiling. Skim any foam from the surface.

Fill Jars

Ladle the hot marmalade into prepared jars, leaving 1/4 inch headspace. Wipe rims clean, center lids, and secure bands fingertip-tight.

Canning Blueberry Lime Marmalade

Refrigerated, the marmalade will keep up to 3 weeks; frozen, up to a year. For shelf-stable storage, process jars in a boiling water bath. Prepare a water bath canner while the marmalade cooks, lower filled jars into the canner with at least 1 inch of water covering them, and process for 10 minutes for half pints (adjust for altitude as noted below).

When processing is complete, turn off the heat and let jars sit in the canner for 5 minutes before removing. Cool jars undisturbed on a towel-lined counter for 12 to 24 hours, then check seals before storing.

Serving Ideas

Spread the marmalade on toast, biscuits, or scones to enjoy the visible ribbons of lime peel. The tropical lime flavor pairs well with coconut-flavored baked goods and tropical fruit. Use it as a glaze for cakes or tarts, swirl it into plain or coconut yogurt, or spoon it over vanilla ice cream for a striking color and bright flavor contrast.

Equipment

• Water bath canner
• Canning jars, lids and bands
• Large heavy saucepan
• Candy thermometer
• Jar lifter
• Canning funnel

Ingredients

• 1 lb limes, washed and scrubbed
• 2 cups water, for simmering (plus more for soaking)
• 2 cups blueberries, fresh or frozen
• 2½ cups granulated sugar

Instructions

• Wash and scrub limes. Quarter each lime lengthwise, then slice each quarter crosswise into very thin slices (about 1/8 inch). Remove and discard seeds.
• Place sliced limes in a large bowl and cover with water. Soak overnight (at least 8 hours) at room temperature to soften peel and reduce bitterness.
• Drain and discard the soaking water. Transfer lime slices to a large heavy saucepan with 2 cups fresh water. Bring to a boil, reduce to a simmer, and cook 10–15 minutes until the peel is very tender.
• Add blueberries and sugar, stirring until the sugar dissolves. Increase heat and bring to a full rolling boil, stirring frequently.
• Boil until the marmalade reaches 220°F or passes the cold plate test (about 8–10 minutes). Skim foam.
• Ladle hot marmalade into prepared jars, leaving 1/4 inch headspace. Wipe rims, center lids, and apply bands fingertip-tight.
• Process in a boiling water bath canner for 10 minutes for half pints, adjusting for altitude. Let stand in the canner 5 minutes before removing.

Notes

This recipe adapts a classic marmalade method and swaps lime for lemon for a brighter, tropical flavor. The overnight soak is essential to soften peel and remove bitterness. Use the cold plate test to check for gel: a spoonful on a chilled plate should wrinkle when pushed.

Altitude Adjustments

• 0 to 6,000 feet: 10 minutes
