Menachot 23: Mixing Matza Dough with Spices

A brief note on today's daf:

• is the kometz permitted if two handfuls have become mixed?
• the Gemara discusses a baraita regarding how matza is baked
• as long as the spices or sesame seeds are less than the amount of dough, the matza is fit for fulfilling the mitzvah at the Pesach seder
• Tosafot wonder if this referred to a clump of spices in one mouthful of matza
• One spice mentioned is called ketzach, nigella sativa of the ranunculaceae family 
• Steinsaltz teaches that this is known as fennel flower, nutmeg flower, roman coriander, blacked or black cumin
• ketzach has been used as a spice, as medicine, and as a domesticated plant
