What each ingredient does

Red raspberries
Provide the main flavor, aroma, and color of the soup.
Granulated sugar
Adds sweetness and balances the tartness of the raspberries.
Cornstarch (in the method)
Thickens the juice as it heats, giving the soup body.

The step that matters

Add the cornstarch to the boiling juice. Cornstarch must be fully dissolved in cold water first, then added to boiling juice while stirring. This keeps it from clumping and lets the starch swell evenly and thicken the soup as it cooks.
