Hi Min, Thanks so much! I’m so sorry that things didn’t come out as planned. Unfortunately, it’s not that easy to replace regular flour with any gluten-free flour blend when it comes to certain recipes. I haven’t developed a gluten-free waffle recipe, so I can’t offer any suggestions of how to change this one. This one shared on Leite’s Culinaria from Shauna Ahern’s book, Gluten-Free Girl and the Chef, is a good place to start. A quick Google search for a gluten-free waffle recipe would also be your best bet.
It’s not always easy to compare waffle makers, because there are a number of different styles: those which make thick Belgian waffles, those which make thin and crispy American waffles, ones which can make both types, and even some which have both corrugated surfaces and flat surfaces so you can fry an egg at the same time you’re preparing a waffle.
The machine works fine, but there are lots of nooks and crannies that are difficult to clean. And the noise to tell you a waffle is "done" is horrific. It's an emergency alarm type sound so every time we use it, the sound nearly sends me running out of the house with my child thinking something awful is happening. I never get used to it. And to top it off, the alert timing is wrong so it serves no functional purpose. If it had no alarm or one that could be disabled, the rating would be 4 stars.
Unless you lead a life of leisure (or run a bed and breakfast) chances are your waffle iron is not going to be a daily-use appliance, so ideally you shouldn't have to allocate much of your kitchen real estate to store it. Since most waffle irons are pretty bulky, we paid special attention to the design—does the size of the machine make sense? Is the space well-used? Does it feel solidly built? Does seem like it will hold up well to cleaning and other wear and tear?
