Step‑by‑Step Instructions for Savory Rhubarb Barbecue Sauce
Step 1: Prepare Rhubarb
Begin by washing 1 pound of fresh rhubarb stalks, then slice them into small, uniform pieces about 1-inch long. This ensures even cooking and a smoother sauce. Place the chopped rhubarb into a medium-sized saucepan to get ready for the adventure of creating your homemade Savory Rhubarb Barbecue Sauce.
Step 2: Combine Ingredients
In the same saucepan, add 1 cup of sugar, 1/4 cup of sriracha, 1/2 cup of balsamic vinegar, and a pinch of salt along with the rhubarb. Stir the ingredients together until well combined, letting the sugar dissolve slightly. This creates a balanced mix of flavors that will soon transform into a delicious sauce over the heat.
Step 3: Cook Sauce
Place the saucepan on the stove over medium heat and bring the mixture to a gentle simmer. Keep an eye on it and stir occasionally for about 15-20 minutes. You’ll know it’s ready when the rhubarb has broken down into a thick, luscious sauce that glistens and smells utterly inviting, making it perfect for slathering on grilled goodies.
Step 4: Blend for Smoothness
Once the rhubarb has cooked down, remove the saucepan from the heat. Using an immersion blender, blend the sauce in the saucepan until smooth and velvety, ensuring that all the chunky bits have disappeared. If you don’t have an immersion blender, carefully transfer the mixture to a countertop blender and blend until you reach the desired consistency for your Savory Rhubarb Barbecue Sauce.
Step 5: Cool and Store
Allow the blended sauce to cool to room temperature before transferring it to airtight containers or jars. This cooling step is crucial as it prevents condensation, which can affect the sauce’s texture. Once cool, your Savory Rhubarb Barbecue Sauce can be stored in the refrigerator for up to two weeks or frozen for future grilling adventures.
