    Small-Batch Strawberry Rhubarb Jam with Maple & Chia

    Published Jul 19, 2020

    Jump to Recipe Print Recipe

    This sweet-tart low-sugar strawberry rhubarb jam is set with chia seed instead of loads of sugar or pectin, for a light, fresh taste that you'll love! Serve this refined sugar-free jam on toast, in PBJs, over pancakes, stirred into yogurt, or in chia pudding.

    I can never get enough of strawberries and rhubarb together. Whether it's in the form of crisp, crumble, pie, cobbler, or galettes, the sweet-tart combo ends up greater than the sum of its parts. The uniquely floral taste of tangy rhubarb melds perfectly with ripe red berries, turning a luscious shade of crimson.

    I've been capturing these alluring flavors in a quick, small-batch jam gently set with chia seeds to minimize cooking and subtly sweetened with maple syrup. It keeps in the refrigerator for up to a couple of weeks, or in the freezer for up to several months. Sometimes I throw in raspberries if I have some hanging around. I hope you love it!

    Ingredients

    This low-sugar strawberry rhubarb jam recipe uses just 4 ingredients, and each plays a vital roll.

    • Strawberries and rhubarb are the stars of this show. You can absolutely use frozen fruit if that's what you've got. Feel free to swap some or all of the strawberries for another berry such as raspberries.
    • Chia seed gives the jam a soft set.
    • Maple syrup adds gentle sweetness and extra flavor.

    How to Make Strawberry Rhubarb Jam

    This jam is quite simple to make. You could probably just throw all the ingredients in a pot, but I like to add them in stages for the best results.

    1. Since rhubarb takes longer to cook than strawberries, start by simmering the rhubarb and maple syrup together until the rhubarb just starts to break down.
    2. Stir in the berries and simmer until the liquid in the pot is reduced by about a third.
    3. Stir in the chia seeds and simmer for 1 minute.
    4. Spoon into jars and chill until set.
    5. Refrigerate for up to 2 weeks, or freeze and enjoy low-sugar strawberry rhubarb jam through the winter months when you're craving something bright.

    Maple-Sweetened: Low-Sugar Strawberry Rhubarb Jam

    Most jam recipes are sugary AF, which is part of the reason I avoid making and eating them. Sugar helps set jam; you can also add pectin to help it set with less sugar.

    This recipe skips the sugar entirely in favor of maple syrup. This refined sugar-free strawberry rhubarb jam recipe is on the tangy side, so feel free to add more sweetener if you like. Rhubarb's tartness means that it does want some sweetener to make it palatable.

    Chia Seed Jam = Strawberry Rhubarb Jam with no Pectin

    Chia seeds have an outer coating with the ability to absorb ten times its weight in water. This quality causes them to form a gel-like consistency when combined with liquid.

    Here chia seed replaces pectin as a gelling agent, helping the jam thicken as it sets in the fridge. This further reduces the need for sugar, which, as I said before, is what sets more traditional jams.

    How to Enjoy Strawberry Rhubarb Jam

    This low-sugar strawberry rhubarb jam recipe is balanced enough to devour straight from the jar with a spoon. But here are some other ways to dress it up:

    • Slather on multi-grain bread, sourdough, or gluten-free nut and seed bread
    • Layer into breakfast chia pudding, tahini chia pudding cups, or overnight oats
    • Pile on gluten-free biscuits or shortcake
    • Spread on PBJs
    • Swirl into oatmeal or yogurt bowls topped with homemade granola
    • Dollop on gluten-free pancakes: sorghum buttermilk, grain-free almond flour poppyseed, or lemon ricotta, or on gluten-free waffles (teff or corn) or almond flour crepes
    • Bake into crumble bars or thumbprint cookies
    • Make it part of an epic cheese platter or chocolate board
    • Put it in gluten-free ricotta tart
    • Use it to top a cheesecake or cheesecake bars or tart
    • Gussy it up in a pavlova, Eton mess, or fools

    Maple-Sweetened Strawberry Rhubarb Chia Jam

    Print Recipe Pin Recipe
    This tangy low-sugar strawberry rhubarb jam is softly set with chia seed for a light, fresh flavor. Perfect with toast, PBJ, yogurt, oatmeal, & more.
    Alanna Taylor-Tobin
    Prep Time: 15 minutes
    Cook Time: 25 minutes
    Total: 40 minutes
    Servings: 2 cups

    Ingredients

    • 2 cups (230 g / 8 ounces) rhubarb in ½-inch lengths
    • ⅓ cup (90 ml) maple syrup more to taste
    • 3 cups (13 ounces / 370 g) stemmed, quartered strawberries or halved if small
    • 1 tablespoon chia seed more if you want a firmer set

    Instructions

    • Combine the rhubarb and maple syrup in a medium saucepan. Place over medium heat and bring to a simmer. Reduce the heat to low and simmer gently until the rhubarb is tender and just starting to break down, about 5 minutes, stirring occasionally.
    • Stir in the strawberries and simmer until the jam is reduced by about a third, 10 - 15 minutes. The berries should be very soft and falling apart but not completely disintegrated; I like them to hold a bit of a shape in the finished jam.
    • Stir in the chia seeds and cook 1 minute more. Remove from the heat. Transfer the jam into jars and chill until set, at least a few hours and up to 2 weeks, or freeze for longer storage.

    Notes

    • You can make this with frozen fruit if you like. Just increase the cooking time if needed. 
    • Feel free to trade some or all of the strawberries for other berries – raspberries, tayberries, blackberries, blueberries, or any others. 
    • See the post above for serving suggestions!
    Variation: Strawberry (or blueberry) Chia Jam
    Omit the rhubarb. Combine 3 cups hulled and quartered strawberries, 1/4 cup maple syrup, and juice from 1/2 a medium lemon in a large saucepan. Bring to a simmer over medium high heat, then lower the heat to maintain a simmer. Cook until the juices bubble thickly and are reduced by about half, 10-15 minutes. Stir in 2 tablespoons chia seeds and cook for 1 more minute, then remove from the heat and mash the berries until mostly broken down.

      What do you suggest as a replacement for maple syrup in your recipes? I do not like the taste of it which is why I ask. I have gone through enough of your recipes to seem to be your go to.

        Hi Jody, in this recipe you could use any sweetener you like! Just add it to your taste. For baked recipes, you could try agave, which has a similar consistency but might be sweeter, I'm not sure. You could also try thinning another liquid sweetener with water, or making simple syrup by dissolving sugar in hot water.

        Most of my recipes prior to last year just use sugar, and so do the ones in my book, so you might prefer those!

      Hi Alanna, just wondering something. I want to try your rhubarb roulade from your cookbook and am wondering if it would work well to use this instead of the rhubarb purée ? I just today finally found fresh rhubarb but don’t have the amount called for in the purée recipe. Looking forward to your response & trying it!

          This worked perfectly, Alanna! The jam complemented the creme fraiche filling in the roulade and just made the flavor and moistness in the cake even better the next day. It makes for a pretty presentation too which is always a plus. The tartness of the rhubarb is offset nicely by the strawberries. It has received very positive reviews from my taste testers :-) It will be on the farmer’s market table this weekend!

    Cherry recipe du jour because #cherryseason: roast Cherry recipe du jour because #cherryseason: roasted cherry ice cream sandwiches with GF double chocolate buckwheat cookies 😋

Here fresh cherries are roasted in sugar and bourbon, pitted and chopped, and mixed with more bourbon. This process releases water and condenses flavor, making a chunky compote that stays soft when frozen into a vanilla ice cream base. 

When sandwiched between these super-chocolatey cookies, the effect is downright addictive. And just the thing for the warm weather we’re currently having in California!☀️

Up first: tart cherry Eton mess with poppyseed almond meringues

These lightly caramelized meringues have a delightful crunch against tangy whipped yogurt and tart cherry compote. Pretty much my dream dessert right here! 

Use sweet cherries if sour cherries aren’t available. Use rich coconut yogurt instead of dairy to make this DF.

These look fancy, but they're actually super simple to make with vanilla-flecked brown butter and a trio of @bobsredmill GF flours that work together to create a dreamy texture. Warm from the oven, these are crispy on the outside with tender middles bursting with butterscotch notes. 

Whip up a batch in under an hour to feel like you just stepped into a posh Parisian patisserie.

At the start of the pandemic, Jay and I started going hiking and forest bathing every week. We always pack lots of snacks and take plenty of time to immerse ourselves in our surroundings. We often spend hours sitting on a blanket, watching the birds and lizards, the way the light plays off of the water, listening to the sound of the breeze and birdsong. I guess it’s actually closer to extreme picnicking than hiking! 

This herbaceous potato salad is one of our favorite lunches to pack. It has protein from jammy boiled eggs, crunchy veggies, creamy potatoes, and a kicky dressing. 

Throw some in a to-go container packed in a cooler and you’ll have a nourishing meal anywhere you like. 

Enjoy this beautiful planet! 🌏🌲🍃
