Reply To: Why did the Bnei Yisroel eat milchigs at har sinai?

Ender: The term “Chazal” usually refers to Tannaim and Amoraim. “Chazal” said nothing about eating dairy on Shavuos. It’s a much later Minhag.

Also, that Magen Avraham has always been a Pele to me as it’s clear that we hold that the blood does not turn into milk. (See Niddah 9a)
