Step 1 : Introduction to the question "5. In a salt shaker, you may encounter a few grains of rice. What is the rice there for?"
...1. To absorb moisture 2. To slow down the flow of salt through the holes in the lid 3. To enhance the flavour 4. To kill salt-weevils There is nothing more frustrating than finding a salt shaker with the contents bound into a solid lump. The rice attracts any moisture in the air, and allows the salt to flow freely. As fas as I am aware, there is no such thing as a salt-weevil.
