Kasher Cookware: Milk And Meat

To kasher pots and pans from milk and meat, you must first ensure that the utensils are completely clean and free from any food residue or grease. If you are kashering a pot that has been used for milk, it is important to wait 24 hours before beginning the kashering process. The basic principle to keep in mind is that the way the non-kosher food substance is absorbed into the utensil is the way it should be expelled. For example, a pot used for stewing can be kashered by boiling, while a pan used for frying or baking can be kashered by using a blowtorch for direct contact with heat.

If you are kashering a pot, fill it with water and bring it to a boil. If the pot is too large to submerge completely in another pot, you can use tongs to hold one side of the pot and submerge it partially for about 30 seconds, then turn the pot and continue submerging it part by part until the whole pot has been submerged. Alternatively, you can fill the pot to the top with water and bring it to a boil. In the meantime, heat a large stone or brick over another burner. Once the water boils, drop the hot stone into the pot using tongs, causing the water to overflow and cover the outside of the pot with boiling water. This method can also be used to create a kashering pot. Remember to always rinse the kashered pot with cold water after the process.

For frying pans that have been used with oil, it is recommended to heat them on a burner set to high heat until a piece of paper touching the pan gets singed. It is important to note that Teflon-coated pans cannot be kashered according to Orthodox rulings.

Pots and pans used to heat liquidy foods can be kashered by hag'alah (boiling)

To kasher pots and pans used to heat liquidy foods, you can use the hagalah method, which involves boiling. Here is a step-by-step guide:

Step 1: Clean the Utensils

First, thoroughly clean the pots and pans to ensure there is no residue or dirt on them. This is important because hagalah only purges the "taste" of non-kosher food absorbed into the utensil, not the actual food or dirt on the surface. Make sure to also remove any rust spots, as food particles can be trapped between the rust and the utensil.

Step 2: Wait 24 Hours

After cleaning, let the utensils rest for 24 hours without being used.

Step 3: Prepare the Kashering Pot

You will need a separate pot, called the kashering pot, for the hagalah process. This pot should be either brand new or kosher for Passover. If it was previously used for chametz, make sure 24 hours have passed since its last use. Before using it for hagalah, kasher the kashering pot itself by performing hagalah on it.

Step 4: Boil Water in the Kashering Pot

Fill the kashering pot with clean water and place it on a heat source. Heat the water to a rolling boil.

Step 5: Submerge the Utensils in the Boiling Water

Completely submerge the entire non-kosher utensil, including its handles, into the bubbling water. If the utensil is too large to fit into the kashering pot, you can use tongs to hold one side and submerge it partially for about 30 seconds. Then, turn the utensil and continue submerging it, part by part, until the whole utensil has been submerged.

Step 6: Rinse the Utensils

Immediately after removing the utensil from the boiling water, rinse it with cold water.

Notes:

It is important to note that frying pans cannot be kashered by hagalah. Additionally, any utensil that may get ruined during the hagalah process should not be kashered, as there is a concern that the owner will not properly kosher the utensil to avoid damaging it.

Frying pans that used oil can be kashered by libun kal (simple purification)

Frying pans that have been used to cook with oil can be kashered by libun kal, or "simple purification". This is one of the four methods of kashering, which involves using heat to remove unkosher substances from items that have become unkosher due to heat. Libun kal specifically refers to heating metal to a high enough temperature that paper (traditionally, a broom straw) touching it scorches. This can be achieved by setting your oven to its highest setting for 40 minutes, or using a self-cleaning cycle.

To perform libun kal on a frying pan, first ensure that the pan is completely clean and free from any baked-on food or grease. Then, place the frying pan on a burner set to high heat. Once the pan is hot enough, a piece of paper touching the pan should scorch.

It is important to note that if a frying pan has been used without oil, it cannot be kashered by libun kal, as this method is not sufficient to remove unkosher substances. In this case, the pan would need to be heated until it glows red-hot, which would typically require a blowtorch and would likely ruin the pan. Additionally, Teflon or enamel-coated pans cannot be kashered.

Metal pans used for baking must be kashered by libun gamur (heating over an open flame)

Metal pans used for baking must be kashered by libun gamur, which involves heating them over an open flame until they are red hot. This process of purification is necessary to remove any absorbed non-kosher flavours or traces of non-kosher food.

To perform libun gamur, you will need to use a blowtorch or an open flame, such as a fire or a set of coals. Heat the metal pans until they are red hot all over. This method of kashering is one of the most rigorous and challenging processes, and it may damage some pans, especially those made from thinner metals like aluminium. For this reason, many people opt to purchase new baking pans instead of attempting to kasher their existing ones.

Before performing libun gamur, thoroughly clean the pans of any baked-on residue. It is advised to let the pans rest, unused, for 24 hours after cleaning and before performing the libun gamur. While some sources suggest that waiting 24 hours is not necessary for libun, it is generally recommended.

It is important to note that not all materials can be kashered. For example, Teflon-coated pans cannot be kashered according to Orthodox rulings due to the risk of flakes ending up in your food. Additionally, some materials, such as glass, are considered unable to be kashered according to certain traditions. If you are unsure about the materials of your pans or the specific requirements for kashering, it is always best to consult with a rabbi or another expert in kosher practices.

Glass baking pans need to be washed according to Conservative halakhah

The Conservative movement's understanding of kashrut largely aligns with that of Orthodox Judaism. However, the Conservative movement allows for more leniency in certain cases. For example, it considers all gelatin as kosher, milk does not have to be cholov yisrael, and red meat does not need to be glatt.

In the context of kashering pots and pans, Conservative halakhah differs from Orthodox rulings in a few ways. According to the Conservative movement, Teflon-coated pans can be kashered, whereas the Orthodox do not allow this. Additionally, glass baking pans only need to be washed according to Conservative halakhah, while the Orthodox rule (in Ashkenazic tradition) states that glass baking pans cannot be kashered and must be replaced.

It is important to note that Conservative Judaism holds that halakha can and should evolve to adapt to the changing realities of Jewish life. As a result, their rulings may differ from those of Orthodox Judaism and may be more lenient in certain cases.

A koshering pot can be created by filling a pot to the lip with water, heating a stone or brick, and then dropping it into the water

To create a koshering pot, fill a pot to the very lip with water and bring it to a boil. In the meantime, heat a large stone or brick over another burner. When the water in the pot is boiling, carefully drop the hot stone or brick into the water using tongs. This will cause the water to overflow and spill over the sides of the pot, thereby covering the outside of the pot with boiling water.

This method can be used if the pot is too big to fit into another pot for koshering. However, it is important to exercise caution when performing this procedure to avoid getting scalded by the boiling water shooting out from the pot. After koshering, the pot should be rinsed with cold water.

Additionally, it is worth noting that the pot used for koshering will also need to be koshered in the same manner after the process is complete.
