Copper pans are popular among cooks due to their high heat conductivity, allowing for even cooking without requiring high heat. They are also versatile, allowing for a variety of cooking methods such as frying, scrambling, and poaching eggs. However, one concern with copper pans is the potential for discoloration when cooking eggs. While copper itself is an inert and non-reactive metal, the tin lining in some copper pans can discolor or react with highly acidic or spicy foods if left in contact for extended periods. To prevent discoloration and ensure optimal cooking results, it is recommended to use copper pans on low to medium heat and avoid leaving food in the pan after cooking. Additionally, copper pans should not be used for storage and acidic foods, such as vinegar or citrus, should be avoided to prevent potential reactions and discoloration.

Cooking eggs on a red copper pan
To cook eggs on a red copper pan, first ensure that the pan is hot enough. You can do this by using the water drop method: flick a few drops of water onto the pan, and if it sizzles and dissipates quickly, it is hot enough. Then, add a little oil, butter, or lard to the pan. Some recipes suggest using a thin layer of oil, while others recommend spraying the spatula with non-stick spray to prevent the eggs from sticking. Next, crack an egg into the pan on low to medium heat and wait until it is cooked properly and comes up the pan. Avoid poking at the bottom of the egg before it is ready. You will know it is ready when it lifts off the pan. Switch off the stove to let it cool, and the egg will slide right off the pan.
It is important to note that copper pans should not be heated to very high temperatures, as this can damage the pan. In addition, copper pans should not be used to cook acidic foods, as the acid can react with the copper and discolor the food or the pan, and copper salts may be released into the food. This is especially true of uncoated or unlined copper pans. To avoid this, choose low-acidic foods when cooking with copper pans, and always use a lined copper pan in good condition to prevent any potential health risks associated with copper toxicity.

The ideal temperature for cooking eggs
While searching for the ideal temperature for cooking eggs, I came across some information regarding the discolouration of eggs in red copper pans. It appears that cooking eggs in a red copper pan is safe and will not cause discolouration. In fact, copper pans are marketed as non-stick cookware that is ideal for cooking eggs at low temperatures.
Now, when it comes to the ideal temperature for cooking eggs, there are a few things to consider. Firstly, the type of egg dish you are preparing will dictate the optimal temperature range. For example, preparing sunny-side-up fried eggs requires a different temperature than scrambled eggs or an omelette.
Secondly, the cookware you are using will also impact the ideal temperature. Different materials have varying heat conductivity, which affects how efficiently they transfer heat to the eggs. For instance, copper is a highly conductive metal, so it doesn't require high temperatures to cook eggs effectively. In fact, cooking eggs in a copper pan over medium or high heat is not recommended, as it can cause the eggs to stick and overcook. Instead, it's best to cook eggs in a copper pan over low to medium-low heat.
In general, when cooking eggs in a non-copper pan, a moderate heat level is usually recommended. For scrambled eggs or an omelette, you typically want to cook the eggs over medium heat until the desired level of doneness is achieved. This ensures that the eggs cook through without becoming rubbery or overcooked.
Additionally, the desired doneness of the eggs plays a role in determining the ideal temperature. For example, soft-boiled or poached eggs require lower temperatures (around 140°F to 155°F) to achieve a runny yolk and partially cooked egg whites. On the other hand, hard-boiled eggs require higher temperatures and a longer cooking time to ensure the yolks and whites are fully solidified and cooked through.

How to prevent eggs from sticking to the pan
While copper pans are non-stick, eggs can still stick to them if the pan is too hot. Copper is a highly conductive metal, meaning it doesn't require much heat to cook food evenly. Therefore, it is recommended to cook eggs on low to medium heat. You can use the water drop method to check if your pan is hot enough. If the water droplet dances and glides about the pan, it is ready.
To prevent eggs from sticking to the pan, you can use butter or oil. Oil forms a barrier between the pan and the egg and also conducts heat better. The steam produced by the egg cooking keeps it from sticking to the pan. If the pan is too cold, steam will not be produced quickly enough, so it is important to get the heat right.
You can also use cooking spray to prevent sticking. Some people prefer butter, while others use coconut oil or extra virgin olive oil. If you are cooking bacon with your eggs, you can move the bacon around as it cooks to prevent sticking.
For scrambled eggs, one method is to mix the eggs in a glass measuring cup with some milk using a fork. Heat the pan with some margarine just below medium-high heat, add the eggs, and let them set. Then, slide a lifter along the bottom from the edges to the middle and swirl the pan to level out the liquid egg. Keep doing this until they are set enough to flip and turn into bigger clumps.

The safety of cooking with copper pans
Copper pans are safe to cook with, provided that they are lined with a non-reactive metal, such as tin. Tin is a durable metal that becomes more stable with age and use. However, it is important to note that highly acidic or spicy foods can cause discolouration or damage to the tin lining. Therefore, it is recommended to avoid cooking or storing acidic foods such as vinegar, wine, or citrus fruits in copper cookware. Instead, use glass, plastic, or pottery for storage.
When cooking with copper pans, it is best to use low to medium heat. Copper is a highly conductive metal, so it does not require much heat to achieve non-stick results. Using high heat can damage the pan and cause food to stick. To test if your pan is hot enough, use the water drop method: sprinkle a few drops of water onto the pan, and if they sizzle and disappear quickly, the pan is ready.
It is also important to avoid submerging a hot copper pan into cold water, as this can cause cracks and damage the surface. For optimal usage and longevity, it is recommended to clean copper pans with a soft sponge and a paste made of equal parts water and baking soda.
While copper is an essential mineral for the body, providing health benefits when consumed through food, ingesting too much copper can lead to toxicity and adverse health effects. Using an uncoated or unlined copper pan can release copper salts into food, potentially causing vomiting, diarrhoea, nausea, liver damage, and kidney issues. Therefore, it is crucial to use suitable copper pans that are in good condition to minimise the risk of copper toxicity.

How to care for and maintain copper pans
Copper pans are beautiful and functional, and with proper care, they can last for generations. Here are some tips on how to care for and maintain your copper pans:
Choose the Right Lining
Copper pans usually have a lining to prevent food from coming into contact with the copper, as copper is reactive and toxic in large doses. Traditionally, copper pans were lined with tin, which is durable and offers excellent non-stick properties. However, tin requires more maintenance as it needs to be re-tinned from time to time. Stainless steel is now a more common lining, as it is more resilient and better at handling high temperatures. However, stainless steel is not as non-stick as tin and is more prone to food adhesion.
Use the Right Heat Source
Copper is a highly conductive metal, making it very energy efficient. It heats up quickly and evenly and cools down just as fast. Because of this superb conductivity, copper works best on gas cooktops, as they can quickly adjust the temperature. Electric cooktops are too slow to shift temperatures, negating copper's advantage. Copper also does not work on induction cooktops in most cases. When cooking with gas, use a gentler heat than you usually would, as copper can do a lot with a smaller thermal input. Be especially careful with high heat if your pan is tin-lined.
Cleaning and Polishing
Each time you use your copper pan, wash it with warm water, dish soap, and a soft sponge. Avoid using a harsh scrubber on the soft tin lining. If your pan has a stainless-steel lining, you have more flexibility, but it's still best to avoid metal utensils to prolong the lifespan of your pan. After washing, you can polish the outside of the pan with a copper polisher like Bar Keepers Friend and a soft sponge. Polishing is optional, especially if you prefer the patina look.
Re-tinning
If you have a tin-lined pan, you will need to re-tin it from time to time. To do this, the old tin lining is stripped away, exposing the copper. Then, new tin is melted into the pan over very high heat and wiped into an even coating. With proper care, a tin lining should last at least ten years.
Cooking Eggs
Copper pans are excellent for cooking eggs, especially with their non-stick properties. When cooking eggs, always use low to medium-low heat. You can use the water drop method to test if your pan is hot enough: flick a few drops of water onto the pan, and if it sizzles and dissipates quickly, it's ready. Add a little oil or butter to the pan to prevent sticking further. For sunny-side-up eggs, wait until they lift off the pan before turning off the heat and letting them cool—they should then slide right off. For scrambled eggs, cook on low heat with a lid on until they're done to your liking.
