Is there a difference between seasoning and flavouring?
The problem is, both Sarge's and Carmi's answers are right depending on who is using the word. Some people use the word seasoning to just mean salt, some mean salt and pepper, and some mean "anything you want to use to bring the flavor to the desired point, including salt, pepper, lemon juice, spices, herbs, etc." If you are dealing with someone in person, it is best to ask. With a cookbook, sometimes you can figure it out from context or from other recipes. Otherwise, you'll have to make your own best call. In my own recipes, I will generally write "taste and adjust seasoning, adding salt and/or more lemon juice as needed".
