In 1971, Oregon track coach and Nike Co-founder Bill Bowerman used his wife's waffle iron to experiment with the idea of using waffle-ironed rubber to create a new sole for footwear that would grip but be lightweight; hence making easier for individual's to be able to increase their speed. Oregon's Hayward Field, where he worked, was transitioning to an artificial surface and "Bill wanted a sole without spikes that could grip equally well on grass or bark dust." He was talking to his wife about this puzzle over breakfast, when the waffle iron idea came into play.  Bowerman's design inspiration led to the introduction of the so-called "Moon Shoe" in 1972, so named because the waffle tread was said to resemble the footprints left by astronauts on the moon. Further refinement resulted in the "Waffle Trainer" in 1974, which helped fuel the explosive growth of Blue Ribbon Sports/Nike.
We considered looking at dual-purpose waffle makers with interchangeable plates such as the T-fal EZ Clean Sandwich and Waffle Maker (SW6100) but ultimately passed. Appliances that try to excel at two disparate tasks often fail at one, and from reading the reviews, it seems clear that this T-fal model—which is now discontinued—might make great sandwiches but fails to make excellent waffles.
Imagine tasting fluffy, Belgian-style waffles for breakfast every morning. Then, imagine the satisfaction of being able to make a vanilla waffle one day and add nuts, fruit or even dessert toppings to your batter on the next. Now, envision this breakfast experience with no mess and effortless cleanup. You can stop dreaming and wake up, the Hamilton Beach® Flip Belgian Waffle Maker is in the kitchen and expecting you for breakfast.
Finally, be aware that if you're getting so-so results from a waffle maker that usually draws rave reviews, the problem might be your batter instead of the machine. Users who substitute pancake batter for waffle batter quickly find out that there is, indeed, a difference between the two. Pancake batter in a waffle iron generally produces a heavy, dense mess that'll stick to the waffle iron like glue, and users warn that some "waffle recipes" found on the back of pancake mix boxes don't do much better. If you're into creative pancake making, you'll do better cooking them on a stovetop skillet or electric skillet, both of which we cover in separate reports.
The earliest waffle irons originated in the Low Countries around the 14th century. These waffle irons were constructed of two hinged iron plates connected to two long, wooden handles. The plates were often made to imprint elaborate patterns on the waffle, including coat of arms, landscapes, or religious symbols. The waffles would be baked over the hearth fire.
The Presto FlipSide Waffle Maker flips from side to side on a hinge, rather than with a rotary motion, like the other models we tested. It does not feature a locking handle, however, so the side-to-side flipping motion easily leads to spilled batter. The unit heats up quickly but never gets very hot, resulting in a long cook time. It features a one- or two-minute timer to indicate when to flip, but the waffles take upwards of 10 minutes to brown, so each waffle requires frequent beeping.
The Black+Decker Removable Plate Waffle Maker (WM700R) is a new model for 2016. You can take the plates out for washing, which is a huge plus, but unfortunately this machine fell short in several other ways during our testing. The indicator lights don’t tell you when a waffle is done, and it has no browning control. Plus, our waffles came out bready rather than crisp, and after a few rounds of baking, the handle got uncomfortably hot.
The Thermostat uses a bimetallic strip to break the circuit when the desired temperature is reached. This is a strip made up of two metals that have different thermal expansion characteristics, such as steel and copper. If one metal expands faster than the other, the strip will warp -- and the motion caused by this warping can do useful work (like breaking the circuit...) In this case, a cam exerts some force on the bimetallic strip using a spring force to keep the contact in place for varying amounts of temperature. For "high" settings, the bimetallic strip must warp a lot more to break the contact than for "low" settings.
“This sweet little baby waffle-maker is a dream. I swear, I squeal every time I pull out a perfectly made baby waffle because they are just so darn cute! Uncomplicated, easy to use and clean. Not a lot of bells and whistles here, but it does the job just right. They’re the perfect Eggo size, not huge like some waffle-makers, and get perfectly crisp. Sometimes, when I’m feeling crazy, I add in some blueberries or chocolate chips. If you’re making a lot, or want to do them quickly, I do suggest getting two, as you can only make one small(ish) waffle at a time with this.”
