To put the method into practice we need a pan suitable for oven cooking . These are pots that can withstand very high temperatures, almost always made of ceramic, soapstone, cast iron or stainless steel.

Fill the pot with water , then pour in half a glass of vinegar and the juice of a lemon . The steam from this solution will help clean the oven and neutralize bad smells .

Set the oven to 250 degrees, then place the pan in and let it rest for 30 minutes.

Immediately after, turn off the oven and let it cool. Before it is completely cold, being careful not to burn yourself, use a cloth or sponge to remove any residue, which will come off easily.
