Why Do Jews Cover Their Kitchen In Foil

Over the years, the Jews have customarily covered their kitchen in foils, which has sparked concerns from non-Jews worldwide.

So why do the Jews cover their kitchen in foil? This practice is usually carried out during the Passover (also called Pesach), and it helps to ensure the surfaces on which the Passover food is cooked are free from chametz. Chametz is food that contains leave ing agents that are strongly forbidden to be eaten during the Passover week.

During the Passover, the Jews prepare their house thoroughly for the Passover. One of the preparation activities is to clear the house of chametz. Burning or throwing the food of all traces of chametz in the house isn’t enough. You have to clean the house thoroughly, especially the kitchen, to ensure it is entirely free of chametz. To ensure no penetration of chametz into the house, the families cover their counters, cooking stoves, and other surfaces with aluminum foil. There will be no trace of chametz in any of them the food consumed during the Passover week.

However, not all homes take the precaution of covering their surfaces with foil; they prefer to embark on thoroughly cleaning to clean the house of chametz before the Passover week. These families usually have a unique set of cookware, appliances, and dishes used only during the Passover week.

So now, we will be looking at the overall effects of foil on food in contemporary society.

As we all know, foil is one of the most famous objects in the modern kitchen. We used it to wrap fresh fish or meat when grilling, to wrap sandwiches as we place them in the microwave to bake, and it is used to cover and protect fresh food from oil, bacteria, and moisture.

Even though it sounds advantageous, it is without its disadvantages. It is just that the advantages surpasses the disadvantages.

The most common foil in the contemporary modern home is “aluminum foil. “So we will be focusing on the aluminum foil.

Avoid Foil When Cooking

Having listed all the potential risks of cooking or using aluminum foil, you must determine the aluminum concentration when cooking; this is because the aluminum foil tends to affect the taste of the food when used for a prolonged time.

In modern homes, the pots and other cookware are continuously oxidized to provide an inert layer that prevents the aluminum from leaching into food. The issue here is that when you scrub your pots after cooking, that layer is washed away, and the aluminum can slip into your food. To prevent this kind of issue, when you get new aluminum pots, before using them, boil water in them a couple of times until the base becomes matt. This process creates a natural oxidation that prevents leaching, which helps your food to be more secure, which also has a positive influence on your health.

But cooking your food in foil is a totally different matter. Aluminum foil is disposable, and so you won’t be able to create the inert layer before using it, which means it can easily leach into the food, and at greater levels, in acidic and liquid food solutions like tomato juice or lemon than food containing alcohol or salt.

However, it is absolutely harmless and in no way affects the safety of the food. This is a harmless reaction that does not affect the safety of the food.”
