Sharp Foods: Difference between revisions

# If the sharp food is cut with a meat knife or cooked in a meat pot and then cooked in a dairy pot or with a dairy spatula or utensil the sharp food is considered not kosher as well as the dairy pot, and the spatula or utensil need koshering. This is true even if the dairy pot, spatula, or utensil is eino ben yomo. This is also true of the opposite case, such as a sharp food cut with a dairy knife.<ref>Dvar Charif 10:13 ch. 185 based on Rama 95:2</ref>  

#This is also true if the sharp food cut with a meat knife is fried in a dairy pan with some oil.<ref>Dvar Charif 10:12 ch. 185</ref>

# If the sharp food is cut with a meat knife or cooked in a meat pot and then it is cooked with another food, if that second food is mixed with milk there is a dispute if the second food with milk is permitted (''nat bar nat bar nat'').<ref>Badei Hashulchan 96:5 quotes that the Pri Megadim is strict since we treat nat bar nat of a dvar charif like one nat so too with three nat's. (Commonly this is known as the opinion of the Even Haozer YD 96.) However, Rabbi Akiva Eiger argues.</ref> For a case of need it is permitted.<ref>Badei Hashulchan 96:5</ref>

# If an onion was cut with a meat knife and put into a parve soup cooking in a dairy pot that wasn't used within 24 hours for dairy the pot is permitted and the food shouldn't be eaten with dairy.<ref>Dvar Charif p. 179 is lenient since it is nat bar nat of hetera in the pot since it is eino ben yomo. Even for the minhag of the Rama 94:5 it isn't necessary to be strict since we can include the opinion that onions aren't charif.</ref>

# If an onion was cut with a meat knife and put into a parve soup cooked in a dairy pot that was used within 24 hours for dairy, some say that the pot is permitted and the food shouldn't be eaten with dairy.<ref>Dvar Charif p. 176 Chedrei Deah 96 and Maharil Diskin 14 based on the opinion of Shulchan Aruch 95:3 that nat bar nat of milk and meat meeting in the water is permitted as well as the Maharam that onions aren't sharp.</ref> But many are strict.<ref>Dvar Charif p. 177 citing Yad Yehuda Pirush Haaruch 95:16 arguing that we can't be lenient based on the Shulchan Aruch 95:3 since the Rama disagrees with that completely.</ref>

#An onion that cut with a meat knife and then cooked in a parve dry dish, such as frying onions with fish, there is a dispute whether the pot is now meat.<ref>according to the Magen Avraham the onion gives off a single taste of meat into the pot, however, according to the Even Haozer the onion gives off the nat bar nat taste into the pot. (He adds the Chavot Daat 122 as well specifically regarding when the onion was cut with a meat knife and not fried in a meat pot.)</ref>

# If a dairy knife is used to cut an onion and it is then put in a meat food if that meat food is liquidy such as a soup and is sixty times the width of the knife the entire mixture and onion is permitted.<ref>The Shulchan Aruch YD 94:6 writes that if vegetables absorb taste of meat and they are then cooked in a milk pot if it can be ascertained how much meat was absorbed in the vegetables, if in the pot there's sixty times the meat everything is permitted. The Rama explains that we don't say that the meat taste should expand to the size of the vegetables since they are all permitted. Maharam Lublin 28 writes that this principle is also true in a case of an onion cooked with a meat knife that is cooked with milk that if there's sixty times the meat that the knife absorbed in the milk it is permitted. Shach 94:23 codifies this. Rabbi Akiva Eiger 94:7 questions this as Shulchan Aruch implies that only if the food is cooked in a milk pot is the vegetables permitted but not if it is cooked in milk. His reasoning is that once milk is absorbed into the vegetables it becomes forbidden.  </ref>
