Kitchen Kashrus Questions

Question:

1. An uncooked Milchig pastry with cheese inside was put into a Parve oven. It cooked for several minutes and the oven was hot. There were also several empty non-stick teflon baking trays in the oven at the time. How can the oven and baking trays be made Parve again – neither have been used in about a month.
2. A room-temperature piece of salami was briefly put on a parve chopping board. The board was immediately washed with cold water. The chopping board is plastic. Can it still be used for parve?
3. Cooked vegetables were defrosting in a parve tupperware container. A milchig pot had water boiling in it. A ladle-full of boiling water was inadvertently put into the parve container to help defrost the vegetables. The water was quickly tipped out. What is the status of the tupperware container?
4. Years ago parve beaters and a mixer bowl was washed in hot fleishig water. Since that incident, the beaters and bowl have been used to mix batter for a fleishig oven, but were always washed separately (above the fleishig sink but never placed with other fleishig items). Now that we may have a parve oven again (see point 1!) can we use these beaters to make a cake for the parve oven?

Answer:

1. Everything is still pareve. One does not need to suspect milchig vapors leave baking food unless one actually sees the vapors (זיעה).

2. The board is still pareve. When there is contact with cold, moist and oily foods the point of contact needs to be washed. Use warm water only. Hot water can make things worse. See Y.D. 91:3. and Shach #4. A fleishig knife, with grease on it that is used to cut pareve food  (like cucumbers) would require the food to be scraped when possible. If the fleishig knife cut fish and scraping it would ruin the fish, a good rinse in warm water is sufficient. See Y.D. 96:5 and pischei teshuva #5. Your case does not require scraping since there is no pressure of a knife.

3. Pareve. The vegetables are also pareve.The hot water, even if it was yad soledes bo, was a kli sheni. Also the milchig pot is to be treated as nosen ta'am lifgam unless you knew it was used for milk in the last 24 hours.
4. What made the hot  water that the beaters and mixer bowl were washed in, fleishig? Was it chicken soup that was heated on the fire? Even if the beaters and bowl are really fleishig (which is unlikely), you could use clean, eino ben yomo, fleishig utensils, to mix pareve, cold batter.
