Step‑by‑Step Instructions for Rhubarb Barbecue Sauce
Step 1: Prep Rhubarb
Begin by thoroughly rinsing your fresh rhubarb stalks under cool water, then chop them into small, even pieces about 1-inch long. You should have roughly 4 cups of chopped rhubarb, which is essential for achieving the perfect tart base of your Rhubarb Barbecue Sauce. This step ensures the rhubarb cooks down evenly, contributing to a smooth and luscious sauce in the end.
Step 2: Simmer Ingredients
In a medium saucepan, combine the chopped rhubarb, sugar, sriracha, balsamic vinegar, and salt. Place the saucepan over medium heat and stir occasionally until the sugar fully dissolves, about 5 minutes. You’ll start to notice the mixture bubble gently, releasing a sweet and tangy aroma that signifies you’re on the right track to creating a delightful Rhubarb Barbecue Sauce.
Step 3: Cook Down
Once the sugar has dissolved, reduce the heat to low and let the sauce simmer uncovered for about 20-30 minutes. Stir regularly to prevent any sticking or burning at the bottom. The rhubarb will gradually break down, and you’ll see the sauce thicken and transform into a glossy texture. Keep an eye on it; it should resemble a chunky ketchup consistency when finished.
Step 4: Cool & Store
After cooking, carefully remove the saucepan from the heat. Let the Rhubarb Barbecue Sauce cool in the pot for about 10-15 minutes, allowing flavors to meld together beautifully. Once cooled to room temperature, transfer the sauce into an airtight container or jar and store it in the fridge. This vibrant sauce can be enjoyed for up to two weeks, making it a perfect make-ahead option for your summer grilling!
