Bishul: Difference between revisions

# Ashkenazim are more strict. Some poskim hold that any accumulation of liquid is considered liquid. A moist food with a drop of liquid on it is still considered solid.<ref>39 Melachos (Rabbi Ribiat v. 2 p. 594) writes that any accumulation of liquid on a food is considered a liquid. His proof is Rav Moshe (Igrot Moshe 4:74:7) and Mishna Brurah 318:32 who imply that any liquid is considered a liquid. Nonetheless, he learns from the Mishna Brurah that moist food is still considered a solid. Additionally a drop of liquid on a food is considered a solid.</ref> However, other poskim define a solid by a food that is edible even when cold. A liquid is something that is only edible when heated up.<ref>Orchot Shabbat p. 14 as explained by Rav Mordechai Willig in The Laws of Cooking and Warming Food on Shabbat p. 27</ref>

# For example, there is a dispute whether ketchup is considered a solid or liquid since it pours (first opinion), on the other hand it is edible cold and so it is considered a solid (second opinion).<ref>Rav Mordechai Willig in The Laws of Cooking and Warming Food on Shabbat p. 27 explains the dispute between Rav Moshe Feinstein (igrot Moshe 4:74:5) and Rav Shlomo Zalman and Rav Elyashiv (Orchot Shabbat p. 14) in this manner. Rav Moshe holds it is a liquid since it pours, while the other poskim assume it is a solid since it is edible cold. Rav Willig accepts the definition of the other poskim.</ref>
