Gently crush some raspberries before adding them to the saucepan for a more intense flavor.For a smoother consistency, blend the cooked raspberries before straining the syrup.Adjust the amount of sugar according to your desired sweetness level.To enhance the citrusy note, add a little lemon juice along with the orange juice.If you prefer a thicker syrup, increase the amount of corn starch slightly.Customize the syrup's flavor by adding a pinch of cinnamon or vanilla extract.Make a larger batch and freeze the excess syrup in ice cube trays for convenient single servings.
