Almond Paste, Marzipan, and Frangipane

Almond paste, marzipan, and frangipane are all almond-based products, but differ in composition and use: marzipan is a sweet, pliable candy-like substance for decorations; almond paste is a coarser, less sweet baking ingredient (filling/paste); and frangipane is a soft, spreadable custard cream used as a pastry filling.

Substitution: Because marzipan is much sweeter and has a different texture, it cannot easily be substituted for almond paste. Frangipane is completely different and cannot be swapped with either. You can turn almond paste into marzipan by adding sugar, but you cannot easily turn marzipan into almond paste for baking.

In some regions, particularly the UK, the terms can be used more interchangeably, but in the United States, they are generally distinct products found in the baking aisle.

Frangipane

It is sometimes referred to as almond cream. And, being more or less like a pie filling, frangipane is never consumed raw because it contains raw eggs.
