A waffle iron or waffle maker is a utensil or appliance used to cook waffles. It usually consists of two hinged metal plates, molded to create the honeycomb pattern found on waffles. The iron is heated and either batter is poured or dough is placed between the plates, which are then closed to bake a breakfast delicacies with a sweet dessert flavor, very similar to pancakes but lighter and sweeter. The appearance is much harder to achieve than a pancake; hence the waffle iron.
Traditional waffle irons are attached to tongs with wooden handles and are held over an open flame, or set on a stove. Most modern waffle irons are self-contained tabletop electrical appliances, heated by an electric heating element controlled by an internal thermostat. There are also two variants of the electric iron: one with removable plates and ones with non-removable plates. Professional waffle makers are usually made of cast iron whereas domestic models are often teflon coated. Many have a light that goes off when the iron is at the set temperature. Most modern waffle irons - particularly cast aluminum ones - are coated with a non-stick coating (e.g. teflon) to prevent the waffles from sticking to them. Cast-iron waffle makers are usually not coated and require seasoning like a cast-iron frying pan.
Modern waffle iron makers offer a large variety of choices. Some waffle irons can make a very thin waffle, capable of making waffle cones or Pizzelle. While there is no set standard of classification for waffle shapes or thicknesses, models that fall within the most common shapes and thicknesses are often labeled as "traditional" or "classic". Models that make thicker and/or larger pocketed waffles are often labeled as "Belgian" waffle makers. In the US, the most commonly used determining factor of whether a waffle is a "Belgian waffle" or not is the thickness and/or pocket size, although the recipes for Belgian waffles and American waffles do differ.
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.
In 1869, American man Cornelius Swartwout patented the stove-top waffle iron. While waffles irons of sorts may have existed since the 1400s, Swarthout intended to perfect the design by adding a handle and a hinge that swivelled in a cast-iron collar., allowing the waffle-maker to flip the iron without danger of slippage or burns..
In 1891 John Kleimbach, a German immigrant living in Shamokin, Pennsylvania became a traveling salesman of waffles after fashioning an iron for the Mansion House Hotel. Kliembach sold waffles for a penny each or ten cents for a dozen. This was popular at the Chicago World's Fair.
It wasn't until 1911 that General Electric produced a prototype electric waffle iron, although production did not begin until around 1918. Later, as the waffle iron became more prevalent, designers worked on making the appliance more attractive on the countertop.
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.
