Salt: Kosher v. table salt
We always use kosher salt in our cooking because its crystals dissolve better in water than ordinary table salt. However, kosher and table salt are not equivalent when you are measuring amounts for a recipe. To further confuse matters, different types of kosher salt measure differently. If a recipe calls for table salt (or just salt), and the amounts are relatively small (e.g., one teaspoon), we simply use the amount called for in the recipe. You can always add a bit more salt to taste. If however, the recipe calls for larger amounts of salt, as would be the case, for example, in a brine, then you should convert the amount called for. Most sources cite 2 types of kosher salt as being widely available: Morton (which is what we use) and Diamond Crystal (which none of us have ever been able to find.) In any case, to convert the amount of table salt to Morton Kosher Salt, multiply the table salt by 1.5; to convert to Diamond Crystal, multiply by 2.
