Torah Temimah on Shemos 12:9, note 17 (on צְלִי אֵשׁ) points to Pesachim 41a.
Sefaria — Exodus 12:9
Sefaria — Torah Temimah on Exodus 12:9

E-Daf — Pesachim 41a
English: Rav Chisda said: One who cooks in the hot springs of Teveria on Shabbos is exempt; but a Pesach that one “cooked” in the hot springs of Teveria — one is liable, for he transgressed “roasted with fire.”
Application of צְלִי אֵשׁ: natural hot water is not fire-heat.
Heat from Teveria’s springs does not fulfill fire-roasting; one who prepares the Pesach that way is liable.
