Which Shaker Does The Salt Go In
There is an actual salt and pepper rule. To identify the salt and pepper shakers, it all has to do with the number and size of the holes and your level of commitment to insanity. The answer, while often taken for granted, hinges on practical design: salt is typically found in the shaker with fewer holes, while pepper resides in the shaker with more holes.
This difference accounts for the different granular structures of each spice and ensures appropriate dispensing. Those wishing to limit their sodium intake (aka, those in the United States) use the top with the fewest holes in it for the salt. Practically speaking though, the real answer is to use whichever top gives you the result you want.
It all depends on the kind of salt and pepper you are using. Generally, salt shakers feature more holes, typically three or more, to accommodate the heavier use of salt in cooking and seasoning. This design allows for a more efficient flow of salt, ensuring that dishes are adequately seasoned without requiring vigorous shaking.
Salt and pepper shakers have different hole sizes due to particle size differences. Salt crystals (0.5-1.5 mm) require larger holes (1-2 mm) for smooth flow and to prevent clogging. Pepper grains (0.5-1.0 mm) need smaller holes (0.5-1.0 mm) for controlled sprinkling and even distribution.
If you're struggling to tell which shaker dispenses salt and which pours out pepper, use this simple trick to differentiate your shakers before you use them. As an alternative to salt and pepper shakers, pepper may be distributed at the table by use of a pepper grinder, while salt may be distributed from a salt cellar or a salt mill. Like many types of vintage home goods, the easiest way to identify a vintage shaker is by turning it upside down (be sure to throw a pinch of salt over your shoulder if any spills out!) and looking for a back stamp or manufacturers mark.
Some finely ground table salts may work well in a two-hole shaker, while some larger sea salts may require the three-hole shaker. The decision of which shaker to use for salt largely depends on the individuals personal preference and the type of salt being used. This led to one theory on the shaker-holes argument: Salt was necessary to sustain human life; therefore, people tended to use more of ithence, it went in the shaker with the most holes.
