Sforno on Exodus 16:23/ספורנו על שמות ט״ז:כ״ג

1את אשר תאפו, the portion of each day’s ration which they would bake in an oven. The subject has been referred to again in Numbers 11,8 as ועשו אותו עוגות “they would make it into cakes.”

2אפו!, now, on the Sabbath eve.

3ואת אשר תבשלו, and the portion of it which you want to prepare boiled, parallel to what is described in the corresponding chapter in Numbers as ובשלו בפרד, “they boiled it in a pot.”
