No mallet. How else to pound chicken breasts?

I have a wonderful bird's eye maple rolling pin that does a much better job than my mallet. Wood rebounds much nicer and you get to hear the "bonk" as well.

I've successfully used the bottom of a small, heavy pot. Also, the side of a meat cleaver works.

I know this is a strange method but it works for me and you only have to visit a hardware store I I bought a rubber mallet washed it throughly and now it's my best utensil. It will flatten even the thickest cutlets, just use wax paper onto and pound very gently you don't want to break the cutlets. Hope this helps!

Agree with Sam, I use a small cast iron skillet.

Should have been clearer. Use the rolling pin like a mallet, not a roller.

Rolling pin. Easy as pie.

The bottom of a heavy cast iron skillet. A small one if you have it.

I (carefully) use the bottom of a heavy pint glass.

Try a full wine bottle...but don't break it on your countertop! Or you could use a rolling pin....
