Food prepared with a Jew's non-immersed utensils

Hi,

Food prepared with a Jew's non-immersed utensils remains kosher, and may be eaten with properly immersed utensils.

(Shulchan Aruch Yoreh Deah 120:16)

Good moed,

Eating with another Jew's unimmersed utensils

Hi,

There is some debate as to whether one Jew may eat with another Jew's utensils, if those utensils were not properly immersed.

Rav Moshe Feinstein ruled that this is prohibited, but in a case of need he was lenient regarding use of the plate itself, for non-liquid foods.

(R' Moshe Feinstein, Igrot Moshe Yoreh Deah 3:22; based on Shulchan Aruch Yoreh Deah 120:8)

Chag kasher v'sameach,

A loophole regarding immersing utensils

Hi,

We have said that a Jew must immerse food-related utensils he purchases.

However: A Jew who purchases food-related utensils in real partnership with a non-Jew need not immerse them, so long as the utensils remain owned in partnership.

(Shulchan Aruch Yoreh Deah 120:11; Shach Yoreh Deah 120:24)

Immersing a knife used for cutting non-food items

Hi,

Because the requirement to immerse utensils is limited to food-utensils, one need not immerse a knife which one purchased for the sake of cutting non-food items. This is true even if that kind of knife is normally used for cutting food.

However: Should one ever use that knife to cut food, even as a one-time event, he would be obligated to immerse it first.

(Shulchan Aruch Yoreh Deah 120:8; Shach Yoreh Deah 120:17)

Have a great day,

Immersing borrowed utensils, Part II

Hi,

One who borrows or rents utensils from another Jew must make sure to immerse them before using them, if they require immersion and the owner did not take care of it.

(Shulchan Aruch Yoreh Deah 120:8)

Have a great day,
Mordechai

Immersing borrowed utensils

Hi,

One need not immerse utensils which are borrowed or rented from someone who is not Jewish.

(Shulchan Aruch Yoreh Deah 120:8)

The berachah on immersing a utensil

Hi,

One who is immersing a single utensil recites a berachah beforehand, "על טבילת כלי, al tevilat keli, on the immersion of a utensil."

One who is immersing multiple utensils, without interruption between them, recites a berachah beforehand, "על טבילת כלים, al tevilat kelim, on the immersion of utensils."

(Shulchan Aruch Yoreh Deah 120:3)

Have a great day,
Mordechai
