Question:

Shalom. If I place a Stam Keli (e.g., a metal pan) (with no food in it) on top of a Blech or Hotplate on Erev Shabbos and on Shabbos Morning remove the Keli to a counter and then place a semi solid, semi liquid item on top of the hot Keli (while on the counter) to warm it up, is this permissible? Is this LeChatchila? Thank you.

Answer:

In your theoretical case, it will depend if the food is considered a solid or liquid. If it is a liquid or if it contains liquid, then if the pan will be able to make the liquid reach yad soledes bo it s not permitted. If however the food is a solid then it would be permitted.

  1. Thank you. And according to most Poskim, most notably Rav Moshe Feinstein, זצ״ל , the temperature of Yad Soledet Bo (in this scenario) would be 43-71°C?

    • Correct. R’ Moshe held that it between these two temperatures it is a safek, therefore we may not allow something to heat up to 43c degrees. On the other hand we can’t say that an item that didn’t reach such a temperature was previously cooked if it didn’t reach 71c degrees. Therefore regarding our question, if a food that has liquid will reach 43 degrees we may not put it on the hot pan.
