You could get either a 6 or 12 muffin tin meant for making English mufffins, or get yourself a set or few of English muffin rings- those usually come 4 per set. With the rings you can use them on the stovetop or in the oven.

I use an electric griddle and rings. Easily fits 8

I also was going to suggest rings. You can do it on the induction with a griddle or large frying pan. Some makers have "pizza pans" out of cast iron that make great round griddles for a big induction element. But the muffin rings are cheap and will let you crowd them on your griddler, if you don't want an induction ready griddle.

You can also just divide the dough, turn the edges to make a ball, and pat lightly to flatten, and not use a ring at all. Do you do a cold start on your griddler? And do they spread? Some doughs are firmer and flatter than others. If you measure the spread you're getting with your current method, you should be able to put them closer together without worry, and fit five or six at a time. I agree that the handmade look is nice. You'll also have more of a tapered edge, rather than flat side wall that you'd get cooking in a ring. Does your frying pan have more surface area? Or can you use it and the electric at the same time?

I use an electric frying pan and an old tuna can

i refuse to by rings when I can reuse

Twoyur, I also use old tuna cans, from back when you could cut out both the top and the bottom, today's cans have those weird bottoms that don't have edges to hook the can opener on. (sigh)

I use an electric griddle and can get at least a dozen on there at once, so it goes relatively quickly.

Annie, can you use a cut from the side can opener like this?

I like the idea of acquiring an electric griddle. That would save loads of time. I can only do at best 4 muffins at a time on the Griddler because of where the heating elements are placed under the griddle plates. If you do not place the muffins in the correct area, they do not brown properly. (As much as I hate the Griddler, it does make great Cuban sandwiches which is why I hang on to it!)

Just a funny remeberance for me. When we got married 40 years ago, I was given a set of the rings with a sheet pan as a shower gift. I still have them and use them all the time not just for the English muffins, but for other things as well.
