If you plan to cook with your cazuela, prepare it with this method:
1. Soak the entire piece in water for at least 2 hours or overnight.
2. Drain and wipe dry.
3. Fill your cazuela with water.
4. Place over low heat on the stove and very slowly bring the water to a boil. (Use a heat diffuser for gas stoves.)
5. Let the water boil down until only a little remains. Do not allow all the water to evaporate as this may cause your cazuela to crack.
6. Cool slowly, then wash by hand.
Your cazuela is now ready for use in the oven or on the stovetop. Always heat and cool gradually when cooking. Rapid changes in temperature cause breakage. Use a heat diffuser on gas stovetops. Note that some discoloration may occur. Always wash by hand.
If your cazuela has not been used for cooking for an extended period of time, it should be cured again prior to use.
