Cooking Airline Meals in Non-Kosher Oven
Airline meals are usually non-liquid, so even though they are single-wrapped, it is OK to heat them in a non-kosher oven as long as no non-kosher food contacts the kosher food container.
 
How To Determine If Non-Kosher Oven Is Clean
To determine whether a non-kosher oven with black or brown spots is clean, scratch them:
  • If the substance crumbles, the spots are OK and you may bake non-liquid food in that oven without covering the food.
  • If the spots do not crumble or they remain immovable or come off in flakes rather than crumbles, consider the oven not clean.
 
Kashering a Dishwasher from Non-Kosher to Kosher
Dishwashers may generally not be kashered except when made of stainless steel (and have no non-kasherable materials inside, such as plastic, silicone, or rubber).
Note If the racks are not stainless steel or if they are coated with plastic or other substances, they may not be kashered.
Setting Down Hot Lid on Non-Kosher Stove Top
Situation You set down a hot pot lid on a non-kosher stove top.
Status
  • Lid is dry and stove is clean: lid remains kosher.
  • Lid is dry or wet and stove is dirty: lid is non-kosher.
  • Lid is wet and stove had hot non-kosher mixtures on it within the previous 24 hours--even if the stove is clean: lid is not kosher.
  • Lid is dry or wet and stove is clean and did not have hot non-kosher mixtures on it within the previous 24 hours: lid is kosher.
Baking Uncovered Food in Clean Non-Kosher Oven: Racks Not Clean
Place two layers of foil under the baking utensil if the oven is clean but the racks are not.
 
Kashrut: Eggs: Hard-Boiling in Non-Kosher Pot
Do not eat hard-boiled eggs cooked in a non-kosher pot.
 
Taste (Ta'am) Transfer: Spicy/Charif: Non-Kosher Utensils
A non-kosher fork, knife, or spoon may not be used to eat or cut spicy/charif food, such as tart pineapple. (If the food is not spicy or hot, you may use a clean, non-kosher utensil on an ad hoc basis.)
Example A non-kosher implement (fork, knife) that is stuck into a spicy/charif or salty food, such as a spicy pickle, will make that pickle non-kosher immediately.
Suggestion Cut onion, garlic, and other spicy/charif foods on a pareve board and with a pareve knife.
Baking Uncovered Food in a Clean, Non-Kosher Oven
You may cook food uncovered in a non-kosher oven if:
  • The oven rack and walls are clean, and
  • The food is not “liquid.”
Note Non-liquid is defined as not being liquid before cooking OR not being liquid after cooking, but the food does not need to be non-liquid at both times.
Example Examples of “non-liquid” foods:
  • Apple cobbler
  • Lasagna
  • Meat (that will create gravy at the end)
  • Pudding
  • Raw fish.
Matza (Unopened)
Kosher for Passover matza in unopened packages stays kosher for Passover and may be used in subsequent years.
Fermented Fruit Juices
Kosher supervision is recommended for fermented non-grape fruit juices (apple cider or fermented pomegranate, cherry, etc.) even if they do not have any additives and contain only pure juice.
Liquers
Many liquers are kosher even without supervision, but many are not kosher and a reliable source should be checked before drinking any liquers.
Note Some liquers are kosher when produced or bottled in one country but are not kosher when produced in other countries.
Bread
Bread made in not-kosher bakeries can be assumed to be kosher ONLY if:
  1.  It has no ingredients other than flour, water, yeast, and salt. French baguettes and some other breads are OK, as are many breads baked in other countries of the same type.
  2.  It is baked on a hearth and not in a pan.
Note On a hearth, any non-kosher ingredients from other baked foods get burned up.
Whiskies
Almost all whiskies are kosher, but check the source to be certain.
Wine
The principal difference between kosher wine (or grape juice) and non-kosher wine (or grape juice) is that the kosher wine must be produced and handled only by religious Jews. However, once the wine or grape juice has been cooked (“mevushal”), it may be handled by anyone, including people who are not Jewish, and it will still remain kosher. Pasteurization may be sufficient to be considered “cooking” for this purpose.
 
Note Many good-quality wines are NOT mevushal and when those bottles are opened must not be handled by anyone who is not a shomer Shabbat Jew.
Pure Alcohol
Pure alcohol is kosher if not derived from any grapes or any other non-kosher source.
