How to Make Roasted Rhubarb Barbecue Sauce: A Step-by-Step Guide

Now that you have your ingredients ready, let’s walk through the process of creating this mouthwatering sauce step by step. You’ll find that making Roasted Rhubarb Barbecue Sauce is not only easy but also a fun way to spend time in the kitchen.

Step 1: Preheat the Oven

Begin by preheating your oven to 425°F (220°C). Make sure your oven is fully heated before moving on to the next step, as this will help the rhubarb roast evenly.

Step 2: Prepare Your Baking Sheet

While the oven is preheating, take a baking sheet and line it with aluminum foil. This will make cleanup a breeze after you’re done cooking. Spray the foil generously with non-stick cooking spray to prevent the rhubarb and garlic from sticking.

Step 3: Roast the Rhubarb and Garlic

On the prepared baking sheet, place 4 cups of coarsely chopped rhubarb and 3 cloves of garlic. Spread them out evenly. Roast in the preheated oven for about 15-20 minutes, or until the rhubarb is soft and begins to caramelize slightly. The garlic should also be soft and aromatic at this point.

Step 4: Puree the Mixture

After roasting, transfer the rhubarb and garlic mixture into a food processor or a blender. Add 1 cup of water to the blender. Blend it until smooth. This will create a deliciously rich base for your barbecue sauce.

Step 5: Combine Ingredients in a Saucepan

Pour the pureed mixture into a medium-sized saucepan. Now, it’s time to enrich this base with more flavors. Add 3 tablespoons of balsamic vinegar, 1/2 cup of brown sugar, 1/4 cup of ketchup, 1 tablespoon of Worcestershire sauce, 1 tablespoon of chili powder, 1/4 teaspoon of cinnamon, and a dash of cayenne pepper. Finish with salt and black pepper to taste. Stir everything together until well combined.

Step 6: Simmer the Sauce

Place the saucepan over medium-low heat. Bring the mixture to a simmer. Allow it to cook for about 10-15 minutes. This simmering process helps meld all those flavors together, creating a harmonious sauce.

Step 7: Cool and Store

Once the sauce has thickened to your liking, remove it from the heat. Allow the sauce to cool completely before pouring it into storage containers. Make sure to keep it refrigerated, where it will last for about 2 weeks.

Serving Suggestions for Roasted Rhubarb Barbecue Sauce

Now that your homemade Roasted Rhubarb Barbecue Sauce is ready, the possibilities for serving it are endless:

• Grilled Meats: Brush it on chicken, ribs, or pork chops during the last few minutes of grilling for a shiny, flavorful glaze.
• Vegetarian Dishes: Use it to complement grilled tofu or jackfruit to bring out subtle flavors.
• Sandwiches: Slather it on burgers or grilled cheese for an exciting new twist.
• Dips or Marinades: Use it as a dip for veggies or as a marinade for proteins before cooking.
• Pasta Dishes: Drizzle over pasta for a bold sweetness that pairs well with creamy sauces.

Pro Tips for Perfecting Your Roasted Rhubarb Barbecue Sauce

1. Taste as You Go: Don’t hesitate to adjust the seasoning while simmering. Taste the sauce and tweak the ingredients until it fits your preference.
2. Experiment with Texture: If you like a chunkier sauce, blend it for a shorter time. For a smooth sauce, blend a bit longer.
3. Mind the Acres of Rhubarb: You can use either green or red rhubarb, but red tends to be sweeter. Adjust the sugar depending on the tartness of your rhubarb.
4. Keep it Fresh: Add fresh herbs like basil or parsley right before serving for a fresh touch that brightens the sauce.
5. Batch Cooking: Feel free to double or triple the recipe. This sauce freezes beautifully, so you can have it on hand anytime you crave it.
