#A solid piece of food that is picked up on a fork or with one's hand is considered a kli rishon until it is placed on the plate or bowl.<ref>Badei Hashulchan 106:21 outlines three approaches as to why the food while in the air is still considered a kli rishon. 1) According to the Maharshal (Yam Shel Shlomo Gid Hanesheh 44, Kol Habasar 75) any solid food (Gush) is considered a kli rishon. 2) Solid food that is in the air that didn't land is considered a kli rishon.(Chazon Ish 9:5) 3) Any food that is in the air that didn't land is considered a kli rishon. (Shach 105:5)</ref> As it is being placed down on the plate or bowl that is considered iruy. After it settles it is considered a kli sheni.<ref>Shach 105:7 citing Darkei Moshe 105:4 clarifies that a hot food that is placed on a plate or bowl is considered iruy while it is being placed down. However, after it settles it is considered a kli sheni.</ref> | #A solid piece of food that is picked up on a fork or with one's hand is considered a kli rishon until it is placed on the plate or bowl.<ref>Badei Hashulchan 106:21 outlines three approaches as to why the food while in the air is still considered a kli rishon. 1) According to the Maharshal (Yam Shel Shlomo Gid Hanesheh 44, Kol Habasar 75) any solid food (Gush) is considered a kli rishon. 2) Solid food that is in the air that didn't land is considered a kli rishon.(Chazon Ish 9:5) 3) Any food that is in the air that didn't land is considered a kli rishon.

#A broken stream of hot liquid (Heb. עירוי שנפסק הקילוח; trans. ''iruy sh'nifsak hakiluach'') poured from a kli rishon has the ability to transfer taste up to the thickness of a peel. Since the stream is broken it only has enough heat to heat up each side but not enough to heat it up and extract a taste and have it absorbed into the other side simultaneously (see [[#Mavliya Umaflit K'echad|further]] for this practically).<ref>Shach 105:5. See however Badei Hashulchan 92:184 that from Shach 92:38 it seems that a broken stream that was originally heated up by the fire is like a kli rishon. Though, Chazon Ish 9:6 cited by Badei Hashulchan maintains that a broken stream is never more than a klipah.</ref> | #A broken stream of hot liquid (Heb. עירוי שנפסק הקילוח; trans.

Also, although the opinion of the Rama as explained by the Chazon Ish is that iruy shenifsak hakiluach is like a kli sheni and has no impact, Badei Hashulchan 91:20 is strict and holds like the Shach.</ref> | ||
#If hot liquids overflow from a pot on the fire and stream along a surface until it touches something but it is a broken stream it is considered a kli sheni.<ref>Trumat Hadeshen 181 and Rama 92:7. The Pri Megadim M"Z 92:26 explains that even though usually a broken stream can transfer taste up to a peel, since the stream ran along a cold surface if it is broken it is certainly considered a kli sheni. Badei Hashulchan 92:147 agrees.</ref> | #If hot liquids overflow from a pot on the fire and stream along a surface until it touches something but it is a broken stream it is considered a kli sheni.<ref>Trumat Hadeshen 181 and Rama 92:7.

#If a knife is used to slaughter an animal according to Sephardim there is no transfer of taste at all, while according to Ashkenazim there is a transfer of taste up to a peel into food but not into the knife since utensils don't absorb as easily as food does.<ref>If a person slaughters a kosher animal with a non-kosher knife there is a dispute in Chullin 8b whether the meat absorbs non-kosher taste. One opinion is that it doesn't and simply needs to be washed, while the other opinion is that it transfers a taste up to a peel. Ashkenazim follow the opinion that there is a transfer of taste up to a peel (Rama 10:1, Shach 10:9), while Sephardim follow the opinion that the meat can be washed. On the other hand, if a person slaughtered a non-kosher animal with a kosher knife the gemara has another dispute whether the knife becomes non-kosher but the halacha according to everyone is that the knife remains kosher (Shulchan Aruch YD 10:3). Rashi Chullin 8b s.v. vhilchata explains that the reason to be more strict on food than the knife is that food absorbs more easily than utensils.</ref> | #If a knife is used to slaughter an animal according to Sephardim there is no transfer of taste at all, while according to Ashkenazim there is a transfer of taste up to a peel into food but not into the knife since utensils don't absorb as easily as food does.<ref>If a person slaughters a kosher animal with a non-kosher knife there is a dispute in Chullin 8b whether the meat absorbs non-kosher taste.

#If a non-kosher knife is used to cut a non-dvar charif and it is cold, if the knife is clean then the food is kosher. If the knife isn't clean then the food needs to be washed off. If the food is soft it needs to be scrubbed thoroughly to remove all of the taste it might have absorbed.<ref>Shulchan Aruch Y.D. 96:5, Badei Hashulchan 96:69 based on Shach</ref> Practically, if you buy a fruit platter or cut watermelon from a supermarket you can assume that they used a clean knife or a knife that is designated for fruit. However, otherwise you can't assume a knife is clean.<ref>[https://jewishaction.com/food/kashrut/cut-fruit-at-the-office/ Rabbi Gersten (OU's Jewish Action Winter 2012)]. If the knife was dirty but was used to cut many fruits which were not dvar charif then theoretically nullification is relevant (Badei Hashulchan 96:65 citing Yad Yehuda). However, if it is possible to wash each one then you should do so because washing each one is a dvar sheyesh lo matirin (Badei Hashulchan 96:65).</ref> | |||
# If a non-kosher knife is used to many lemons and it is impossible to tell which was cut first and which last, then all are permitted because the non-kosher knife only transfers taste to the first lemon and afterwards its taste is mitigated by the taste of the lemon. The first lemon is nullified by the others.<ref>Rama Y.D. 96:4, Badei Hashulchan 96:63</ref> | |||

# Kosher and non-kosher food which were salted together or if there's an interaction between a kosher food and non-kosher food through the medium of salt there could be a transfer of taste up to a peel, klipah.<ref>Gemara Pesachim 75a, Chullin 112a, Shulchan Aruch Y.D. 91:5</ref> | # Kosher and non-kosher food which were salted together or if there's an interaction between a kosher food and non-kosher food through the medium of salt there could be a transfer of taste up to a peel, klipah.<ref>Gemara Pesachim 75a, Chullin 112a, Shulchan Aruch Y.D. 91:5</ref> | ||
