How It’s Used
The most popular use for millet flour is as an addition to or replacement for more traditional wheat flour. Baking generally requires a combination of “wet” ingredients like water, milk, and eggs with “dry” components such as flour, sugar, and various starches. Cooks typically use ground millet in much the same way that they would use any other flour. Millet has a distinctive flavor and can lend a good “crumb” to cakes and cookies, but baked goods made only with millet often turn out too crumbly, often to the point of falling apart and disintegrating. Cooks often need to experiment a little bit to get the right proportions for a given recipe.
Popular Recipes and Dishes
Millet flours are most commonly used in desserts and sweet breads largely because of the grain’s naturally sweet flavor. It tends to lend itself well to cakes, cookies, and muffins, and pairs well with things like honey and chocolate, and some bakers find that they can actually reduce the sugar in recipes when they use ground millet. Many people use it to balance more savory flavors, too, though. It can be used to add bulk to things like meatloaf, or can form a unique batter for fried fish or chicken.
Cooking experts usually say that millet flour can be used in the same ways that regular wheat flour can be, but they don’t normally advise complete substitutions in recipes. In most cases it’s usually best to start with about a 3-to-1 ratio of wheat to millet, then adjust according to taste and dough consistency. The flours may look about the same on the outside, but they are made up of really different things, and they tend to react pretty differently when cooked. The gluten in wheat acts as a binding agent that helps all of the ingredients hold together. Since millet is gluten-free, foods made with this flour tend to crumble much more easily.
As a Substitute for Wheat Flour
This flour is very popular with people who are on gluten-free diets. Some people are allergic to the gluten protein, while others have medical conditions, like Celiac disease, that make it hard or impossible for them to process the protein. Some people also choose to live gluten-free lifestyles as a means of embracing better health or regaining more control and awareness of the food they eat. Millet flour can be a good choice for people in any of these categories who want to enjoy foods that normally contain wheat flour, but again straight substitutions rarely work out. Gluten-free baking usually turns out best when people combine different flours, adding in wheat-free binding agents like xanthan gum to help the dough stay elastic. This is especially important for things like cookies or cakes that need to retain a chewy, somewhat consistent texture; things like crackers or flatbreads may still turn out if they’re somewhat crumbly.
Most yeasted breads also require the addition of some sort of gluten-like substance in order to rise. Yeast feeds on sugars and starches in order to activate, and bread made only with millet might not rise very much.
Milling and Refinement Process
Millet is grown as a food crop in many parts of Asia and Africa, usually in dedicated fields or plantations. It tends to grow in a conical shape, in some sense resembling an ear of corn. The cones are picked during harvesting, either by hand or machine, then are stripped of their grains and processed. When making flour, manufacturers typically compress the grains, then pulverize and grind them into an even consistency.
There are a couple of different ways of refining the flour. The most traditional is known as “stone grinding,” and usually involves pressing the millet with slabs of hard stone. This can be done by hand, and for centuries it was; more modern milling technology means that machines more often do the work, but the idea is the same. The grains can also be passed through industrial grinders, a process that is faster but tends to be somewhat less precise than stone grinding. More of each grain can be lost this way, and the risk is that the end result will be slightly less nutritious as a result.
Grades and Types of Flour Available
Different regions of the world tend to grow slightly different variations or species of millet. Pearl millet is usually the most common for flour, but other related varieties, like proso or kodo, may be used as well. A lot depends on location, availability, and demand.
Some millet flours are also sourced only with organic grains. Different countries tend to have slightly different definitions of “organic,” but in most cases it means that the plants were grown without pesticides or chemicals of any kind.
Basic Nutritional Data
Millet is a whole grain, and many health experts claim that eating a diet rich in whole grains can help improve heart health and can contribute to a healthy weight. The grain is also a very good source of protein and iron, and is high in dietary fiber. People who suffer from hypothyroidism should generally avoid eating millet, though, as a number of studies have shown a connection between millet consumption and impaired thyroid production. Anyone with this or other medical conditions should talk to a medical professional before dramatically modifying their diets, whether with millet or anything else.
