1 Serving Size is 1 Cup of batter, which makes one full Belgian Waffle, so no partial waffle servings here in this recipe. I have never tried to freeze them, but if you ahve frozen other waffles before I imagine these would freeze just as well. If you swapped over to Almond Flour you would need to use 1 & 1/2 Cups of Almond Flour. Almond FLour would give you 1-2 more net carbs per waffle roughly.
What we didn’t like: This is a big and bulky unit, making it a difficult fit in small spaces. Without a drip tray, there is potential for mess. (However, because it's a flip model, you need less batter to fill up the iron, so drips are also less likely.) There was some unevenness in cooking, with the edges browning a touch faster than the rest. The deep wells and fixed plates make cleanup difficult.
The Krups GQ502D took a little more time than some of the other models we tested to bake waffles. In our tests, waffles typically took about seven or eight minutes to cook, while the Presto FlipSide, for one, cooked a thicker waffle in about half the time. But the machines that cooked faster also tended to overcook, or to develop hot spots. A few extra minutes of waiting time is a small price to pay for golden, even-toned waffles, and the wait isn’t so bad when you can make four waffles at once.
I searched everywhere. I unsuccessfully raided the kitchen cupboards with the hope I’d find the recipe scribbled on an index card splattered in batter. After months of searching, I finally found it in the turquoise journal I filled with recipe notes from when I wrote the book. Somewhere between cacao percentages and the perfect crumb-to-apple ratio on a crumble was a nonchalantly scribbled list of ingredients for this gilt-edged Belgian waffles recipe.
While this Cuisinart is undoubtedly a top performer at a great price point, it does only cook one waffle at a time, and the Wirecutter editors point out that it's not as sturdily built as some of the competition -- a point echoed by many users. That may make this waffle iron best for either small groups or occasional waffle-making. That said, Cuisinart offers a three-year warranty -- right up there with some pro-level appliances that cost six times as much. The Cuisinart WMR-CA is also versatile, with users saying it's even great for making foods like hash browns, bacon and potato cakes.
Cooks can use a convenient appliance like a double waffle maker or a countertop oven to save time and space. The baking plates of a double waffle iron are coated to prevent sticking so the Belgian waffles don’t get caught when removing the pastries from the unit. The flip design of a double waffle iron makes it easy to perfectly brown and then remove each waffle. If the waffle maker accidentally gets left on, its automatic shutoff feature turns it off. This preserves the life of the device and avoids the risk of an overheated electric appliance causing a fire.
Essentially, waffles are a form of griddle-cake based on flour, milk, eggs, butter, oil and leavening that are cooked on both sides simultaneously in a mold that takes the form of a gridded surface. Because of the "teeth and gaps" of the waffle mold or "iron", considerably more of the surface area is heated and caramelized relative to the "pancake" -- thus, the waffle has more taste and a crispness that enables it to serve as a support for other foods. Waffles serve many of the same roles in sweets as toast serves in savories.
Flemish waffles, or Gaufres à la Flamande, are a specialty of northern France and portions of western Belgium.[69] The original recipe, published in 1740 by Louis-Auguste de Bourbon in Le Cuisinier Gascon, is as follows: Take "deux litrons" (1.7 liters or 7 cups) of flour and mix it in a bowl with salt and one ounce of brewer's yeast barm. Moisten it completely with warm milk. Then whisk fifteen egg whites and add that to the mixture, stirring continuously. Incorporate "un livre" (490 grams or 1.1 pounds) of fresh butter, and let the batter rise. Once the batter has risen, take your heated iron, made expressly for these waffles, and wrap some butter in a cloth and rub both sides of the iron with it. When the iron is completely heated, make your waffles, but do so gently for fear of burning them. Cooked, take them out, put them on a platter, and serve them with both sugar and orange blossom water on top.[70]

Criteria for what makes an ideal waffle are somewhat subjective: I happen to like mine crunchy on the outside but fluffy in the center, but maybe you like yours golden and crispy? Still, some technical standards are pretty universally accepted, and those were what we focused on during our test. A good waffle iron should heat evenly and cook batter consistently from top to bottom and side to side without burnt spots or raw patches. It should allow enough steam to escape during the cooking process as to produce waffles that are structurally firm and not soggy. It should also be reliable, repeating the same results batch after batch, and easy to clean. 

You can freeze waffles -- why pay the Eggo people to charge a lot for something that you can make cheaply. After the waffles have been cooked in the waffle iron, put them out on a cooling rack. When they are cool, place them in a plastic bag taking out as much air from the bag as possible. Then freeze the bag of waffles. The next time you want a quick waffle, microwave one from the freezer for about 45 to 60 seconds. They are almost as good as fresh waffles.
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.
