I like freshly ground coffee, so I only grind as much as I need. So, what happens if you buy coffee that’s already ground, is 1/4 cup of coffee beans the same as 1/4 cup ground coffee? It turns out, no.
Portion control is important. For example when making meatballs, if their sizes are different, they will cook differently. If you’re monitoring calories or some other intake, you’ll have a more accurate record when the portions are known. Using a scoop when making ganache balls (think truffles!) ensures you’ll get an accurate yield.
