Potential new cafe owner, here.
I worked this weekend at a diner-style cafe that I’m intersted in purchasing. The place has two gas griddles. After the shifts, I scrubbed down both griddles with a grill screen and bacon grease. Both griddles were devoid of any of what I would call seasoning (like I have on my cast-iron pan at home). They were basically bare metal. Is this the best way to maintain griddles or should they have a black/brown coating on them?
