I just made these for my brother and I and used them for hamburger buns. My brother is a fussy eater, he said they were "interesting" but he ate all of it. I loved them. We both agreed that they were too flimsy for a burger. I used the original receipe but used 2T flaxseed meal and 2T oat flour. The only way I can think to make them "stiffer" is to use a smaller diameter bowl but I'm thinking that will just make them taller and still too soft. Any ideas?
