Food & Cooking Recipes Quick & Easy Recipes Stewed Rhubarb 3.0 (82) Close Yield: 1 cup Use this recipe to make our Meringue Cupcakes with Stewed Rhubarb and Raspberries. Directions Place the rhubarb, sugar, and water in a medium saucepan set over medium-low heat. Simmer gently, stirring occasionally, until sugar is dissolved and rhubarb is almost tender, about 8 minutes. Using a slotted spoon, remove the rhubarb from the liquid, and transfer to a medium bowl; set aside. Raise heat to medium, and continue simmering liquid until thickened and reduced to 1/2 cup, about 10 minutes. Remove from heat. Transfer reduced liquid to a small bowl to cool. Add the cooled thickened liquid to the reserved cooked rhubarb, and stir to combine. Cook's Notes It is important that the rhubarb is cooked at a gentle simmer or it will quickly turn to mush. Do not recombine the rhubarb and cooking liquid until the cooking liquid is cool, or the rhubarb will overcook.
