Avoid cooking acidic or salty dishes in tin, as these can cause tin leaching.
Use a Barrier
Use a barrier, such as a non-stick coating or a layer of oil, to prevent tin from coming into contact with food.
Don’t Heat Tin to Extreme Temperatures
Avoid heating tin to extreme temperatures, as this can cause the metal to break down and leach into food.
Alternatives to Tin
If you’re concerned about the health risks associated with cooking with tin, there are several alternatives to consider:
Stainless Steel
Stainless steel is a popular alternative to tin, offering excellent durability and resistance to corrosion.
Cast Iron
Cast iron is another popular alternative to tin, offering excellent heat conductivity and a non-stick surface when seasoned properly.
