Regarding the After-Blessing on Yogurt

Shalom uveracha,

1. If one shakes the yogurt well and drinks it like a beverage, one does not recite an after-blessing on it, unless one drank a reviit within about 5 seconds.

However, when one eats it with a spoon without shaking it, its law is like food, and therefore if one ate from it an amount of a kezayit within the time required to eat a peras (7.5 minutes), an after-blessing should be recited (based on what is explained in Seder Birkat HaNehenin of the Gra, chapter 8, section 8, that food which has melted so much that it is fit for drinking has lost the status of food. Likewise, a liquid that has congealed to the point that it is fit for eating has lost the status of a liquid, even if it has enough moisture to wet another object in a way that it can in turn wet something else).

According to the opinion of Rabbi Ovadia Yosef, of blessed memory, one does not recite an after-blessing on yogurt even if one did not shake it, unless one drank a reviit within about 5 seconds (based on what is explained in his book Yabia Omer, volume 8, Orach Chaim, siman 25, subsection 6).

2. On frozen slush, one should recite an after-blessing if one eats from it an amount of a kezayit within the time required to eat a peras, and according to Rabbi Ovadia Yosef, of blessed memory, one does not recite an after-blessing.

With blessing,

Hillel Meirs
