Pectin NH is a type of low methoxyl (LM) pectin that has been modified to be thermally reversible - it can be set, re-melted, and set again (reheated and reused). Used as a thickener primarily for preparing glazes for fruits tarts and pastries. It is typically used in low-sugar pastry fillings and glazes, vegan desserts, low-fat dessert, that you would like to set without adding flavor.
