I was recently making my Japanese Style Puff Pancakes and could not find my metal ring mold ANYWHERE! So I used a shaped one. Yesterday, I realized I could just make one out of wax paper. These DIY ring molds work great when you want your pancakes or eggs to stay in a perfect circle shape, like when you're making Egg McMuffins. Just cut a strip of wax paper, staple to secure, and pour in liquids.
