Salonika recipe for חרוסת

 

חרוסת recipe        The שבלי הלקט writes to put into the חרוסת, some ground up earth or ground up brick for זכר לטיט. This is based on the  "גירסא ברשב"ם פסחים קט"ז ע"א  "וחרס שכותשין בו הדק זכר לטיט The Birkei Yosef (Chida) quotes the Maharam de Lunzano  who ridicules this שגעון. He claims it came about because of the wrong Girsa of חרס instead of  חרוסת. The Birkei Yosef  also quotes the Bais David who claims that the elders of Salonika testified on the Minhag in Salonika of grinding up a certain stone based on the Girsa of חרס in the Rashbam
