Similarly, the original Macarons des Sœurs were created by two 18th Century nuns, Marguerite Gaillot and Marie Morlot, who lived in an abbey in the heart of Nancy. It"s possible one of the nuns brought some form of the recipe with them upon joining the sisterhood and then perfected it. In 1792, a decree abolishing religious congregations led to their expulsion from the abbey. The nuns fled and took refuge with a local doctor, supporting themselves by making and selling their macarons.
