Step‑by‑Step Instructions for Rhubarb Barbecue Sauce
Step 1: Prepare the Rhubarb
Start by rinsing and trimming the rhubarb stalks, then chop them into small pieces about an inch in size. This prep ensures even cooking and enhances the flavors in your rhubarb barbecue sauce. You’ll want approximately 4 cups of chopped rhubarb, which will serve as the tangy base for your incredible sauce.
Step 2: Combine Ingredients in Saucepan
In a medium-sized saucepan, combine the chopped rhubarb with sugar to taste and 1 cup of balsamic vinegar. Stir the mixture well to coat the rhubarb and evenly distribute the flavors. This step is crucial, as the balsamic vinegar will enhance the tangy profile of the rhubarb as the sauce cooks.
Step 3: Simmer the Mixture
Place the saucepan over medium heat and bring the mixture to a gentle simmer. Stir frequently, allowing the flavors to meld together as the rhubarb begins to soften, which should take about 10 minutes. Keep an eye on it to prevent sticking, and you’ll notice the mixture bubbling gently, signaling that it’s on the right track.
Step 4: Thicken the Sauce
Once simmered, reduce the heat to medium-low and allow the rhubarb barbecue sauce to thicken. Continue cooking for an additional 15-20 minutes until the rhubarb breaks down, and the sauce reaches a sticky consistency. You want the sauce to coat the back of a spoon nicely, indicating that it’s ready for the next step.
Step 5: Add the Heat
Stir in sriracha to the thickened sauce to add a kick of heat, adjusting the amount to suit your taste preference. If you prefer a milder version, start with a small amount and increase gradually. The interplay of the sweet, tangy, and spicy flavors will create a perfectly balanced rhubarb barbecue sauce.
Step 6: Cool and Store
Once your sauce has reached the desired consistency and flavor, remove it from the heat and let it cool to room temperature. Transfer the cooled rhubarb barbecue sauce into clean jars or an airtight container, allowing for easy storage. You can refrigerate it for up to two weeks or freeze it in portions for later use, guaranteeing you always have this delicious sauce on hand!

How to Store and Freeze Rhubarb Barbecue Sauce

Rhubarb Barbecue Sauce Recipe FAQs
What is the best way to choose and prepare rhubarb?
Absolutely! When selecting rhubarb, look for firm, glossy stalks that are vibrant in color—avoid any with dark spots or signs of wilting. For preparation, rinse the stalks, trim off the ends, and chop them into one-inch pieces for even cooking. This will ensure your rhubarb barbecue sauce has a consistent texture and flavor.
How do I store rhubarb barbecue sauce?
You can store your rhubarb barbecue sauce in an airtight container in the refrigerator for up to two weeks. Make sure the sauce is completely cooled before sealing. This way, it stays fresh and ready for your next grilling adventure!

What should I do if my sauce is too tart or too sweet?
No problem! If your rhubarb barbecue sauce turns out too tart, you can stir in a little more sugar or a splash of honey until it reaches your desired sweetness. Conversely, if it’s too sweet, adding a bit more balsamic vinegar can help restore balance without overpowering the other flavors. Always taste as you go!
Are there any dietary considerations for this barbecue sauce?
Absolutely! This homemade rhubarb barbecue sauce is naturally gluten-free, but if you have allergies, double-check all ingredients—especially any hot sauces you might use. You can also adjust the sugar to accommodate dietary preferences, such as using a sugar substitute for a lower-calorie option.
