2.4 Griddle Seasoning
Caution: Although this griddle plate is made of steel, the surface is relatively soft and can be easily
scored or dented by the careless use of a spatula or scraper.
To avoid damaging the plate surface, be careful not to dent, scratch, or gouge it. Do not attempt to
knock off any loose food that may be on the spatula by tapping the corner edge of the spatula on the
griddle surface.
To ensure optimal cooking performance, the griddle surface must be seasoned before its first use.
The metal surface of the griddle is porous, and food can get trapped in these pores and stick, so it is
important to fill them up with cooking oil before cooking.
Seasoning gives the surface a slick, hard finish that will help the food release easily.
To season the griddle plate, follow these steps:
1. Clean the griddle surface with a non-abrasive cleaner and rinse with water.
2. Dry the surface with a clean cloth or paper towel.
3. Apply a thin layer of vegetable oil or shortening to the griddle surface using a clean cloth or paper towel.
Make sure to coat the entire surface, including the edges.
4. Turn the griddle on and set the temperature to low burner setting.
5. Allow the griddle to heat for 30 minutes to 1 hour,
or until the oil on the surface begins to smoke and the surface turns brown.
6. Turn off the griddle and allow it to cool down completely.
7. Use a scraper to remove any excess oil or food residue from the surface.
8. If necessary, repeat this procedure 2 to 3 times to ensure that the griddle surface is slick.
9. Apply a thin layer of oil to the surface before storing the griddle.
Repeat this seasoning process periodically, depending on the frequency of use, to maintain the
griddle's non-stick surface. Avoid using abrasive cleaners or metal utensils on the griddle surface, as
they can damage the seasoning and cause food to stick.
