I don’t think that the geometry of the waffle iron (shape, or depth of indentations) has any effect on the taste. Grease older waffle irons with some oil or melted butter before you begin to bake. I have had some success with spraying the hot iron with aerosol cooking oil like PAM. If waffles get to stick to the iron, dig out the mess and re-grease the iron. Modern teflon waffle-makers do not need any surface treatment. However, with some practice and seasoning, nothing ever really sticks to a well-cared for waffle iron.
The instructions say to warm up the waffle iron on heat setting 7, but there is no heat setting 7. The waffle iron has a knob on top numbered 1 through 6. I can't actually rotate the knob to numbers 5 and 6 though; the knob is physically stopped from rotating at 4. When I rotate the knob the other direction, I can rotate past 1 almost a full 360 degrees (stopping just before I reach 6 from the opposite side). The iron seems to heat up as soon as it's plugged in regardless of how the knob is rotated, so as far as I can tell there is no "off" setting even if I've rotated the knob to well below 1. Since I can't tell how the knob actually maps to heat settings (if the knob even does anything at all) I'm afraid to even try actually poring waffle batter onto the thing..
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?
In 1887,Thomas Edison built a research laboratory to be devoted to the "rapid and cheap development of inventions." Eventually, about 200 scientists, engineers, and technicians were employed there to invent to order, “useful things that every man woman and child wants… at a price they can afford to pay.” The "Edicraft" line came close to fitting this paradigm -- it was developed in the late 1920s when electric appliances were a growing industry that generated high profits. The "Edicraft" line included a clamshell type toaster, a sandwich grill, a waffle iron [below], a combination grill/waffle iron and a coffee urn/water heater (the “Siphonator”.) The entire line was of high quality but were expensive, on the order of $25 per unit -- equivalent to $800 in 2011! The Edison Company stopped production of appliances in 1934.
A company that offers a generous warranty is a company that believes in their product — and also believes that they won’t have to replace many waffle irons under said program. A warranty also gives you peace of mind, since you know that you’re guaranteed a functioning appliance for at least as long as the warranty is good for (and hopefully much longer).
The Chef’sChoice Classic WafflePro 852 was our former runner-up when the Chef’sChoice 840B was unavailable. Although this model was an initial favorite in our testing, with tasters praising its waffles’ consistency and crunch, it makes only two thin, American-style waffles at a time, whereas our pick makes four. We also found that this model had a tendency to burn waffles when the dial was on the highest setting.
