Why is food sticking?
Usually the griddle needs additional seasoning, more preheating, or a
lighter coating of oil.
Why is my griddle changing color?
Darkening steel is normal and expected.
Can I leave it outside?
Only if protected from moisture with an appropriate cover.
How long should I preheat?
Generally 10--15 minutes depending on weather conditions and model.
What's the easiest first recipe?
Smash burgers are an excellent first cook because they teach heat
control without requiring complicated timing.
