Kashrus Archives - AskTheRav

If you are staying in a Jewish owned and operated Airbnb room, but it is at least occasionally rented out to Non Jewish people at times, is there any Cheshash to use the toaster oven being as that you may not know exactly what they may have put inside of it? Is it alright or make a difference if it’s wrapped in foil? This in a situation where I cannot ask the owner (who is Frum) and/or he is not likely to know the Metzius himself one way or another.

The toaster oven may not be used unless the procedure mentioned below is done. We cannot assume that it is kosher, as the non-Jews are renting the home with…

If I use a Fleishig mixing bowl and utensils to mix a batter and then bake it in a Pareve oven, can I have that food together with Milchig food, for example the bread with butter?

Yes.

We fried onions in a meat pot which had not been used for more that 24 hours. We then prepared a Parve soup. Do we need to wait after eating the soup before eating milk foods?

Although the soup is considered Fleishig, you may have Milchig afterwards. See here.

Bread was baked in a Fleishig oven. (In other words, meat had been roasted uncovered in the oven within 24 hours previously.) Someone, ignoring the warning sign on the bread package, cut off a slice of that bread and toasted it in a Milchig toaster oven to eat with cinnamon and sugar topping. The toaster oven probably was not used within 24 hours. Is there a Kashrus problem with the toaster oven? Is there a problem with the Milchig plate the hot toast was put onto? And what is the status of the Parve knife used to spread the margarine on the bread?

The toaster oven, the plate and the knife are all fine. Sources: רמ״א יו״ד צה, ב.

Can/does one need to kasher a glass table?

Glass cannot be Kashered. If the table was used to put hot food directly on the table (or hot pots with liquid under it) the table is Treif. Make…

ילד שפך חלב לתוך סיר של מרק עוף, ואיני יודע כמה חלב הוא שפך, אם שפך רבע כוס חלב, יש שישים, אם זה הי’ חצי, אין שישים. אני לא רואה שינוי במראה של המרק, מה הדין?

יש להקל אם מדובר על הפסד מרובה. מקורות: נעשה ע׳י קטן דינו כנשפך. ולכן בנדו״ז, בבשר עוף בחלב שהוא דרבנן, אפשר להקל בהפסד מרובה. וגם אם יש…

I made a sauce which had onion and garlic cut with a Milchig knife and made in Milchig frying pan. I then poured the sauce onto beans that were cooked in Fleshig pot they were put in a Fleishig bowl, and it was hot. I realized that there is probably an issue with the bowl so I put it aside. But then it was put in the dishwasher and put away. I now do not know which bowl it is. What should I do?

Assuming the bowl was not used for hot Fleishig, or even if was used for hot Fleishig but more than 24 hours before, you may use all the bowls.…

I have a typical metal salad bowl that I rarely but occasionally use with dairy, but always wash it with the dairy dishes, and it was accidentally put in the Fleishig dishwasher with the dirty dishes from Shabbos. What is it’s current status?

The bowl should be Kashered. The dishwasher and all the other dishes are fine.

Can we take water from our Shabbos kettle, to warm a baby bottle in a paper Kli Shlishi? The baby bottle is Milchig, the kettle is Pareve, and our kitchen sink and all our other kitchen utensils are Fleishig.

You are allowed to put a baby bottle even in a Kli Sheni (assuming that the contents of the bottle consists only of liquid, or previously cooked solid food).…

I was of the understanding that we should not use mother’s milk for our baby if it came from a mother who consumes Cholov Akum. Is this indeed correct?

Yes, it is correct. Sources: See Rema (Yoreh Deah 81:7) & Shach 81:25 & Taz 81:12. See for example Igros Kodesh vol. 1 pg. 238 (non-kosher food that…
