Which biblical law did the rabbis imitate, when they forbade items even batel b'rov? Which items are never batel? Define birya? Is a cabernet wine a different min than a merlot? Are grapes and grape juice two minim? Can a raw steak become batel b'rov? If A (asur) fell into B (mutar), without shishim, and then the mixture falls into C, does there need to be shishim in C for A+B, or only for A? Do we say ein bishul achar bishul both by shabbos and basar b'chalav? Is there roasting after boiling? What temperature is yad soledes bo? Is chaticha na'aseh neveila biblical? If part of a mixture that was asur b'mashahu falls into another mixture, is the second mixture asur? Chumash-Mishpatim: Where is it derived that ein adam meisim es atzmo rasha?
