When it comes to cooking with a copper pan, not all oils are created equal. The choice of oil can impact both the performance of the pan and the taste of the food. While olive oil is a popular choice for many dishes, it's not the best option for copper pans. This is because olive oil, especially extra virgin olive oil, has a low smoke point and can carbonize at high temperatures, forming a layer on the pan that affects its non-stick properties and can give food a burnt taste. So, what are the best oils for copper pans?

What You'll Learn
Oils to use: vegetable, canola, grapeseed, and peanut oil
When it comes to copper pans, the type of oil you use is important. Oils such as olive oil and butter should be avoided because they cannot withstand high temperatures. When used on copper pans, these oils form a carbonized layer that affects the non-stick qualities of the pan and does little to prevent tarnishing.
So, which oils should you use? Here are some of the best options:
Vegetable Oil
Vegetable oil is a great option for copper pans. It has a high smoke point, typically ranging from 400-450 degrees Fahrenheit, making it ideal for high-heat cooking. Vegetable oils are also refined, which means they have minimal impurities and free fatty acids, which is exactly what you want when seasoning a copper pan.
Canola Oil
Canola oil is another excellent choice for copper pans. It has a slightly lower fatty acid content than virgin olive oil, contributing to a higher smoke point. Canola oil's smoke point can reach 400 degrees Fahrenheit, only 5 degrees less than the highest range of olive oil's smoke point.
Grapeseed Oil
Grapeseed oil is a fantastic option for copper pans due to its exceptionally high smoke point of about 420 degrees Fahrenheit. This oil's secret lies in its low nutrient content, which helps raise its smoke point. Grapeseed oil is also relatively inexpensive, making it a popular choice for vinaigrettes.
Peanut Oil
Peanut oil is a great choice for copper pans, despite its potential for a low smoke point due to the fibre retained during extraction. However, refining raises peanut oil's smoke point to an impressive 450 degrees Fahrenheit, making it a superb option for high-heat cooking.
In summary, when it comes to choosing oils for your copper pan, always opt for those with high smoke points, minimal impurities, and low free fatty acids. Vegetable, canola, grapeseed, and peanut oils are all excellent choices that will help you maintain the quality and performance of your copper pan.

Oils to avoid: olive oil, butter, and margarine
When it comes to copper pans, the type of oil you use is crucial. Oils such as olive oil, butter, and margarine should be avoided for several reasons.
Firstly, these oils cannot withstand the high heat required for cooking or seasoning copper pans. Olive oil, for instance, has a low smoke point, and when used on a copper pan, it forms a carbonized layer that affects the non-stick qualities of the pan and does little to prevent tarnishing. This carbonization is detrimental as it is the result of oil burning, and it prevents effective seasoning.
Secondly, butter is mainly composed of fat and animal proteins, which denature rapidly when exposed to heat. This can lead to the formation of harmful substances when used on copper pans.
Margarine, especially low-fat margarine, is also not recommended for copper pans. While it can be used for flavour, it is not suitable for high-heat cooking or seasoning.
To effectively season a copper pan, it is essential to use oils with high smoke points, such as vegetable oil, canola oil, grapeseed oil, or peanut oil. These oils can withstand the high temperatures required for seasoning without burning or forming a carbonized layer.

High smoke point oils: refined oils, grapeseed, and peanut oil
When cooking with a copper pan, it's important to choose the right type of oil to avoid smoking and potential health hazards. Oils with a high smoke point are ideal for high-heat cooking methods such as frying, sautéing, and searing. Here's a detailed guide to three types of high smoke point oils: refined oils, grapeseed oil, and peanut oil.
Refined Oils
Refined oils are created by removing impurities and free fatty acids, resulting in a higher smoke point. The refinement process involves high-temperature heating, filtering, bleaching, and deodorizing to eliminate compounds that don't interact well with heat. This process produces neutral-flavored cooking oils that can withstand higher temperatures. Examples of refined oils include canola oil, sunflower oil, and soybean oil.
Grapeseed Oil
Grapeseed oil is a popular choice among chefs due to its high smoke point of 420°F. It has a clean, neutral taste that plays well with other ingredients. Grapeseed oil is often used in vinaigrettes and is ideal for sautéing and stir-frying. Its high smoke point makes it suitable for high-heat cooking without imparting a burnt flavor.
Peanut Oil
Peanut oil comes in two varieties: unrefined and refined. Unrefined peanut oil has a powerful scent and flavor, with a smoke point of 350°F. Refined peanut oil, on the other hand, has a more subtle flavor and a higher smoke point of 450°F. Refined peanut oil is excellent for deep-frying, sautéing, and stir-frying. Its nutty flavor also makes it a good choice for certain dishes, such as Indian cuisine.
In summary, when using a copper pan, it's best to opt for oils with a high smoke point to avoid smoking and potential health issues. Refined oils, grapeseed oil, and peanut oil all have high smoke points, making them suitable for high-heat cooking methods. Remember to consider the specific needs of your dish and choose an oil that complements the flavors of your ingredients.

Oils for seasoning: canola, grapeseed, and sunflower oil
When seasoning copper pans, it is important to use oils with high smoke points. Oils with low smoke points, such as olive oil and butter, are not suitable for seasoning copper pans because they cannot withstand high temperatures. When used on copper pans, these oils form a carbonized layer that affects the non-stick qualities of the pan and does little to protect it from tarnishing.
Canola oil, grapeseed oil, and sunflower oil are all suitable for seasoning copper pans. These oils have high smoke points, which range from 400 to 450 degrees Fahrenheit, making them ideal for the heat-intensive procedure of seasoning.
Canola oil has a low percentage of fatty acids, ranging from 0.2% to 1.2%smoke point of about 420 degrees Fahrenheit due to its low nutrient content. The low amount of trace nutrients in grapeseed oil is essential in raising its smoke point. Sunflower oil is also a healthy oil with a high smoke point, although its exact smoke point is not mentioned in the sources.
When seasoning a copper pan, it is important to follow the correct procedure. First, scrub the pan with mild dish soap and warm water, then dry it thoroughly with a paper towel or lint-free cloth. Next, apply a thin layer of oil to the pan using a paper towel or lint-free cloth. Preheat the oven to between 350 and 450 degrees Fahrenheit and place a sheet of aluminum foil on the bottom rack. Place the oiled copper pan upside down in the centre of the middle rack and bake for 60 minutes. Finally, turn off the oven and allow the pan to cool for about 30 minutes.
