Start by rinsing the rhubarb under cool water to remove any dirt. Then, using a sharp knife, chop the rhubarb into half-inch pieces for even cooking.

In a small saucepan, combine the chopped rhubarb and sugar. Ensure the sugar is evenly sprinkled over the rhubarb pieces.

Cook the rhubarb and sugar mixture over medium heat, stirring occasionally for about five minutes.

Remove the saucepan from heat and stir in a splash of vanilla extract.

Once your sauce is mixed, allow it to cool at room temperature for about 10-15 minutes before serving.
