Reply To: Why is Yad Soledes Bo so Cold?

“I have always understood that YSB was a temperature which was not simply uncomfortably hot but a temperature at which one’s hand would reflexively recoil. To my mind, the commonly accepted lower limit of 110 does not come close to meeting the the description.”

That’s essentially exactly what I was saying in the original post. See Ubiquitin’s comment about what R. Belsky said on this, which helps a little bit. Also, in the Reb Moshe mentioned above he calls 160 “vadai yad soledes bo,” which probably implies that’s the actual temperature where a normal, adult hand would recoil. 110 might be for an extremely sensitive hand (or an unsuspecting hand as in R. Belsky’s shittah) that we’re choshesh for.

Would there be kashrus ramifications where we could rely on 160 if they’re d’rabbonon? (Not asking as a serious shailah, so don’t say “ask your LOR”)
