How to make sweet potato flour... scroll towards the bottom of the recipes. There are many wonderful recipes here, sweet potato donuts, etc. I havent' tried them but want to in the near future as I can now buy organic sweet potatoes.

It's like a historical recipe site.

Of course, I'm assuming everyone will ignore any suggestion to use it along with wheat flour.

HOW TO MAKE SWEET POTATO FLOUR
There are several grades of this product and quite as many ways to manufacture them. Each one of these flours or meals (as most millers insist upon calling them) has a particular character of its own and is therefore, adapted to certain uses the other products are not.
These sweet potato flours are generally speaking of three kinds.
First: Those made from the uncooked potato.
Second: Those made from the cooked potato.
Third: Those made from a careful system of roasting, or from the starch making process. The first two will interest the housewife most so, therefore, I will dwell almost or quite exclusively on these.
FLOUR No. 1. FROM THE RAW POTATO
Here, all that is necessary is to wash, peel and slice the potatoes real thin, dry in the sun, oven or dryer until the pieces are quite brittle, grind very fine in a clean coffee mill, spice mill, or any type of mill that will make wheat flour or corn meal; bolt through fine cloth in the same way as for other flours.

The fine flour-like particles will pass through and the coarse granular meal left on the bolting cloths.
USES
This kind of flour is fine for making mock rye bread, ginger snaps, wafers, waffles, battercakes, custards, pies, etc. Bread can be made with it, but it makes a dough deficient in elasticity, bread dark in color and a loaf which dries out quickly.
The coarser meals can be cooked in a. great variety of ways and make very palatable dishes, they Are to be soaked in warm liquid (whatever is desired. to cook them in) when soft, proceed as for grated potatoes.
FLOUR No. 2. FROM COOKED POTATOES
For the making of this flour the potatoes are broiled, or steamed (preferably the latter) until done, sliced or granulated by mashing or running through a food chopper and dried until they become very brittle, they are made into flour and meal exactly the same as given for Flour No. 1.
USES
This kind of flour is especially fine for bread, cakes, pies, puddings, sauce, gravies, custards, etc.
Indeed, most people consider a loaf made in the proportion of one-third sweet potato flour to two-thirds wheat flour, superior in flavor and appearance to all wheat flour.
Many experiments have proven that either the mashed sweet potato or the sweet potato flour may be used in bread up to as high as 50%, but at this point it becomes decidedly potato-like in texture and flavor but not unplatable or unwholesome.
FLOUR No. 3. FROM PULP
The sugar and starch has been greatly reduced. This flour is made from the pulp after the starch has been removed, it is dried without cooking, ground and bolted exactly the same as recommended for the other flours.

When made into puddings, pies, blancmange, etc., the same as shredded cocoanut, it resembles it very much in taste and texture and is very palatable, and is a most welcome addition to the dietary.

It can also be used in the baking of bread and is especially valuable where people object to a loaf with the least bit of a sweet taste, also where they wish one with as little starch and sugar as possible.
SWEET POTATO STARCH
HOUSEHOLD METHOD
This is very easily made, all that is necessary is to grate the potato, the finer the better, put into a cheese cloth or thin muslin bag and dip up and down, in a vessel of water, squeezing occasionally, continue washing as long as the washings are very milky.

Allow it to settle five or six hours or until the water becomes clear, pour off; rewash the starch, which will be in the bottom of the vessel, stir up well, allow to settle again, pour off the water and let dry, keep the same as any ordinary starch.
USES
Use exactly the same as cornstarch in cooking; I am confident you will find it superior to cornstarch; it makes a very fine quality of library paste, and has very powerful adhesive qualities.

In certain arts and trades it is almost indispensable.
SWEET POTATO SUGAR
By saving the water which the pulp was washed in first, in the starch making process and boiling down, the same as for any syrup, a very palatable, non-crystalline sugar will be the result; this sugar or syrup can be used in many ways.
Here in the South and other sections of the country where fresh sweet potatoes can be had almost or quite the year round, the flour is not a necessity for bread-making; but for commercial purposes there are almost unlimited possibilities, and is destined to become more popular as fast as the public finds out what a delicious, appetizing and wholesome product these flours are.

Our method of using follows with the hope that thousands of housewives will try out this most satisfactory way to add something new, wholesome, attractive and economical to the menu.
