Too big for gyoza unless you have a mouth like Mick Jagger
Update:the 3.75” is still a little large for premade gyoza wrappers. They do fit but only just and that makes it fiddly to get them formed without any gaps. When you’re powering through making a hundred at a time fiddling around getting them right is a pita. I now think 3.25” to 3.5” is the perfect size for both wonton wrappers and premade gyoza wrappers and I have a 3-piece set coming now that includes a 3.25” one. I don’t understand why the perfect size range for premade wrappers is so hard to find. I have now made 5 orders of these things trying to get one that works easily with premade wrappers. For the time being I’m still using the 3” with wonton wrappers, we’ll see about the next one.Original:I’m talking gyoza here, not dumplings and not empanada’s.The common size press/crimpers are 3” 3.75” and 4”.The 4 is too big, the 3 is too small and a 3.75 I think will be juuuust right, it’s in the mail to me now.Others complain these are flimsy, which is true, but they do work and they’re much better made than most of the others with the closed loop handles. They give a little when you really push them to get a solid crimp and I haven’t used them enough to actually break one. Keep the crimper DRY and it won’t stick to the dough.I only use premade gyoza wrappers and in a pinch 4” wonton wrappers which are thinner. The savings of making your own wrappers over buying them is dwarfed in my mind by the giant pita you have to go through to knead and sheet the dough, not to mention the equipment expense.
