Common Mistakes to Avoid When Cooking Corn
Even with such a simple dish, mistakes can happen. Here are some common pitfalls:
- Overcooking: Overcooking leads to tough, mushy kernels. Follow the recommended cooking times for each method.
- Salting the Water Too Early: Adding salt to the boiling water before the corn is added can make the kernels tough. Salt after cooking.
- Not Removing the Silk Properly: Use a vegetable brush or your hands to remove all the silk.
