Useful to know
Coconut macaroons use coconut as a central ingredient and differ from French almond macarons. King Arthur’s recipe describes a distinct mixture and shaping method. [1]
The similar English names can hide different products. Check the ingredients and photograph before borrowing instructions from another recipe. Baking and portion size should follow the coconut version rather than a method intended for smooth almond shells. A shared sweet flavour is not evidence that the texture or preparation should match.
