When I'm cooking and baking, I've noticed that whenever I follow a recipe I meticulously measure the ingredients, using special measuring spoons and cups. If a recipe calls for a teaspoon of baking powder, I scrape the excess off to make sure it's a level teaspoonful.
Thinking back to my childhood, I've decided all that precision probably isn't necessary.
When, as small girl, I watched my mother cook, if the recipe called for a teaspoon of something, she got a regular teaspoon out of the drawer. Now, there is no universal size for such teaspoons, so I'm sure the amount she used varied, depending on what spoon she grabbed; she never scraped it off to level it, either. It was the same for a cup: Mother didn't use a special measuring cup back then. She used a coffee cup, most of which hold either more or less than the eight ounces that a measuring cup holds.
Knowing what an excellent cook my mother was, I realize that I could be a lot more casual about my measuring. Not that I could change, even if I wanted to; it's a habit I somehow picked up the one year I took Home Economics in high school. The teacher stressed the importance of proper measuring, and I still have to do it that way.
How about it? Are you a precision measurer, or a casual one?
