As soon as fit for cracking, and before becoming so dry that the kernels break badly, the nuts should be shelled. The hammer and a solid block of wood, or a piece of metal with a shallow cupped depression in which to place the nuts while held for hitting, is the most common outfit in use. Various handpower machines are appearing on the market, and already designers are at work attempting to devise power machines. The former have been in use for several years. The latter are mostly quite new and untried. About all that can be said regarding such machines is that they are much needed and that it is not improbable that there will soon be several makes of efficient machines in the field.
Grading the Kernels
As soon as the shells have been cracked, the kernels should be extracted. All large pieces, including chiefly quarters and whatever halves there are, should be separated into three shades: lights, darks and intermediates, as previously mentioned. All sound, small pieces, regardless of shade, should be put into a fourth grade and all unsound kernels and particles too small to separate from minute particles of shell, should be put into a fifth grade and fed to poultry in moderate quantity at one time.
Unless given artificial heat before packing for shipment, the kernels are fairly certain to become moldy and even to cake together in a solid mass while in transit. To do this they should be placed in trays or pans and put above or back of a kitchen stove where they will not get hot enough to be injured. The hand should be run through the kernels not infrequently so as to detect any excessive heat and also to determine by experience the proper degree of dryness.
After being kept warm and being frequently stirred until the kernels seem properly dry they may be removed and allowed to become cool. They should then be re-examined with the hand so as to determine the apparent dryness. If they feel at all moist, they should be returned to the drying position and the operation repeated. The writer has had no personal experience in this matter and so cannot give precise directions. However, the farm wife can probably work out a very satisfactory system in her kitchen.
Packing and Shipping
Although previously discussed, the importance of clean, sanitary and attractive containers for shipment can scarcely be overstressed. Without such precaution no one need hope to work up a permanent business, for, regardless of how secure he may feel with the trade he will eventually find his customers turning to others who are willing to go to this trouble.
When the time comes for shipping the boxes may be closed up and delivered promptly to the transporting agency. The containers should again be opened as soon as the destination is reached and an examination made as to the moisture condition of the kernels.
Handling Other Nuts
So far as harvesting and hulling hickory nuts is concerned, the matter is not at all complicated. Good nuts drop with the first sharp frost. Those with good kernels inside become automatically separated from the hulls. Those which do not easily become separated from the hulls should be discarded as they are rarely of any value and should not become mixed with the good nuts. With a moderate amount of curing these nuts should be ready for market. They usually bring better prices in the shell than do walnuts; but on the other hand they are in less demand after being shelled. Perhaps this is because the trade has not been built up but it is a recognized fact that black walnut kernels are practically in a class by themselves among the nuts of the world, in the extent to which they retain an agreeable flavor in cooking. Hickory nut kernels should be given a much greater place than they now occupy in the cooking and baking for the farm table. A few finely chopped kernels mixed with breads, cakes, or cereals will be found highly acceptable to most palates.
