Can you replace instant tapioca pearls with pectin?

No, you cannot directly replace instant tapioca pearls with pectin, as they serve different purposes in cooking. Instant tapioca pearls are used primarily as a thickening agent or for texture in recipes like puddings and pies, while pectin is a gelling agent that helps to set jams and jellies. If you need a thickening agent, you might consider using cornstarch or flour instead, depending on the recipe.
