The common advice is that aluminum woks generally should not be seasoned in the same way you would season carbon steel or cast iron woks. Seasoning creates a patina of polymerized oil that protects the underlying metal and prevents food from sticking. Aluminum is reactive and seasoning typically doesn't adhere well. Because aluminum is a softer metal, this layer can flake off more easily. However, creating a light protective layer is still possible and beneficial:
Lightly Preparing an Aluminum Wok for Cooking
While a true "seasoning" isn't achieved, a light preparation can help reduce food sticking:
-
Clean the Wok Thoroughly: Use hot, soapy water and a non-abrasive sponge to remove any manufacturing oils or residue. Rinse and dry completely.
-
Heat the Wok Gently: Place the wok over medium-low heat.
-
Apply a Thin Layer of Oil: Add a small amount of high-smoke-point oil (like vegetable, canola, or peanut oil) to the wok. Spread it thinly and evenly over the entire surface with a paper towel. You want the thinnest layer possible.
-
Heat Until Light Smoke: Heat the oil until it just begins to lightly smoke.
-
Wipe Down and Repeat (Optional): Carefully wipe away the oil with a clean paper towel. This helps ensure a very thin layer remains. You can repeat steps 3-5 one or two more times.
Important Considerations:
- Aluminum Reactivity: Aluminum can react with acidic foods, potentially causing discoloration or affecting flavor. Avoid cooking highly acidic ingredients (like tomatoes or vinegar) for extended periods in an unlined aluminum wok.
- Alternatives: If you're concerned about sticking or reactivity, consider using a wok made of carbon steel or stainless steel.
- Cleaning: Avoid abrasive cleaners or scouring pads, as these can scratch the aluminum. Use a gentle sponge and soapy water.
- Anodized Aluminum: Some aluminum woks are anodized, creating a non-reactive surface. These do not require seasoning.
Why Not True Seasoning?
The heat required for true seasoning can potentially warp or damage an aluminum wok due to its lower melting point compared to carbon steel or cast iron. Aluminum also doesn't develop the same kind of patina that adheres well over time.
