Step‑by‑Step Instructions for Rhubarb Sour Belts
Step 1: Prepare the Rhubarb
Begin by washing and chopping fresh rhubarb into small pieces, approximately 1 inch in size. In a medium saucepan, combine the chopped rhubarb with enough water to submerge them, usually about 1-2 cups. Place the saucepan over medium heat and bring the mixture to a gentle simmer. Cook for 10-12 minutes until the rhubarb is soft and has broken down, becoming mushy and vibrant in color.
Step 2: Blend the Mixture
Once the rhubarb has softened, remove the saucepan from the heat and let it cool for a few minutes. Transfer the cooked rhubarb and any remaining liquid into a blender. Blend on high until smooth, ensuring there are no chunky bits left. If you prefer a smoother texture for your Rhubarb Sour Belts, consider straining the purée through a fine-mesh sieve to remove any solids, then return the purée to the saucepan.
Step 3: Sweeten the Purée
Place the smooth rhubarb purée back on medium heat and stir in granulated sugar, lemon juice, and any optional sweeteners like honey or maple syrup. Continue to cook on low, allowing it to simmer for about 10 minutes. Stir occasionally, watching for the mixture to thicken and coat the back of a spoon, indicating that it’s nearing the desired consistency for your Rhubarb Sour Belts.
Step 4: Thicken the Mixture (Optional)
If you’d like an even chewier texture, prepare a cornstarch slurry by mixing a tablespoon of cornstarch with a small amount of water. Gradually pour this mixture into the simmering rhubarb purée while stirring continuously. Cook for an additional 2-3 minutes, keeping an eye on the texture; it should be thick enough to spread yet still pourable.
Step 5: Spread the Candy Mixture
Line a baking sheet with parchment paper or a silicone mat for easy removal. Pour the thickened rhubarb mixture onto the prepared baking sheet, using a spatula to spread it evenly into a layer about 1/8 inch thick. Smooth out the surface as best you can to ensure uniform drying and an even texture for your Rhubarb Sour Belts.
Step 6: Dehydrate the Belts
Preheat your oven to the lowest temperature setting, usually between 150-170°F (65-75°C). Place the baking sheet in the oven and let the mixture dehydrate for 6-8 hours. Check periodically; it should dry out but remain slightly pliable. When ready, the mixture will no longer be sticky and should have a shiny finish that indicates it’s perfectly dried to become your delicious Rhubarb Sour Belts.
Step 7: Cut Into Strips
Once the Rhubarb Sour Belts have cooled completely, remove the baking sheet from the oven. Use kitchen scissors or a pizza cutter to slice the dried candy into strips of your desired width. The strips should be flexible but not breakable, ensuring the chewy texture that makes these sour belts so delightful.
Step 8: Coat and Store
To finish, if desired, toss the cut strips in a mixture of superfine sugar and citric acid to give them a sweet-sour coating that enhances their flavor. Then, store the finished Rhubarb Sour Belts in an airtight container for up to one week, ensuring they’re a fresh and fun treat ready to enjoy at any time!
