The thermostat allows the automatic control of the temperature in the waffle iron. However, the "Twin-O-Matic" also has a thermometer -- a device that indicates the actual temperature of the iron. The principle behing the thermomenter is basically the same - a bimetallic strip is made with the property that its warping is a linear function of temperature. This strip is connected to a lever mechanism that causes the small needle to rotate. Hence, the position of the needle is a direct function of the temperature. The dial is calibrated to reflect this.
Wells continued to play a role even during the Swing Revival of the 1990s. On Monday nights, the Harlem Renaissance Orchestra played in a small corner of the restaurant and many of the original Lindy Hoppers (including Norma Miller and Frankie Manning) were regulars, joined by whatever newcomers (like the Rhythm Hot Shots) may have been in town. I made the pilgrimage to Wells in 1998. I loved the fried chicken and waffles, but I was not so thrilled about the carpet on the dance floor.
A previous version of this guide was written by Winnie Yang, who is now a Wirecutter editor. Yang worked in the food industry—with stints in a restaurant kitchen, cookware retail, and chocolate making—for over a decade. She was the managing editor of the print quarterly The Art of Eating and has written for that magazine as well as for Condé Nast Traveler, Feast, Jamie, Saveur, and Tasting Table, among other publications.
The Krups GQ502D, a brand-new model for 2016, is the best waffle maker we’ve found. Not only does it produce beautifully golden, crisp-on-the-outside, evenly browned waffles, but it also has a number of features that make it easier to use than most other machines out there—and make it worth the price. A numbered dial gives you careful control over waffle doneness, and a light paired with a loud beep tells you when your waffles are done. This machine makes four thick waffles per batch, so you can easily feed a crowd (or just one or two). The nonstick plates, which release waffles cleanly without the need for extra oiling, are removable, so cleanup is a breeze. And the compact design allows you to store the Krups either flat or upright, so it fits conveniently in most kitchens.
As always, though, with any kitchen appliance, user reviews are king because they tell how the appliance does under real-world conditions with a real person at the helm -- and how long they hold up under that real-world use. Combining all those terrific resources with our own kitchen experience led us to our recommendations for the waffle irons that are easiest to use and clean, and, of course, make a perfect waffle.
This illustration anthropomorphizes the Twin-O-Matic and notes that post-war demand for small appliances will be a "half billion dollars" (about $100 billion in 2005 dollars), and encourages dealers to sign up to sell Manning-Bowman appliances. This is actually a very sad artifact, because the Manning-Bowman company was in deep financial distress because they could not get materials -- particularly chrome -- during World War II. This was an attempt to sign up dealers so that credit and financing could be obtained to last out the materiel shortages imposed by the War. It did not work, and soon thereafter, Manning-Bowman sank into a sea of red ink. The company's assets, including its spectacular Art Deco designs, were sold to the Bersted Corporation of Fostoria, Ohio. Berstead watered down the designs and made low-priced "drug store" versions of many Manning-Bowman appliances. (The Sandwich Grill on our Kitchen Aplliances page is a good example of this "cheapening" process.) Alas, Manning-Bowman met an inglorious end, but it was merely a foretaste of the vast wave of shoddy appliances made in faraway dictatorships that suffocate the American marketplace today.
