Into a microwave safe bowl, add 1/2 cup of water. Cut a lemon in half, squeezing the juice into the water. Drop the two halves into the water. Place in the microwave, and heat on high for 3 minutes. Let it stand for another 5 minutes. Don’t be tempted to open the door. When the timer goes off, use a dry towel to clean up the mess. (For step-by-step images, click here.)
Is the interior of your Dutch Oven stained brown? Do you have burn spots on your stainless steel pots? Use Bar Keepers Friend, water, and elbow grease to remove. In general, try cooking with fats (oil and butter) at lower heats. If you're needing to char something, opt for a cast iron.
