Stabilized cream: when the foam carries other layers

Useful to know

Stabilizing whipped cream helps it hold its shape longer or support layers in a dessert. King Arthur distinguishes this task from a simple topping that will be eaten immediately. [1]

Use the stabilizer, quantity and incorporation method specified by the recipe. Adding arbitrary starch or gelatin is not an equivalent method. Consider the other ingredients and intended texture as well. Shape stability is not a separate rule for safe storage: refrigeration of the finished dessert must be planned independently.
