Q:

stove top griddles

are stove top griddle only for gas top stoves? 

A:

The stove top griddles I have used worked equally poorly on electric as on gas. 

A:

I have a cast iron 'griddle' for stove top use.  I use it on my electric range and it works fairly well, but if there is any foodstuff on the stove it gets baked on and is hard to clean, so I have to scrupulously clean the stovetop first.
