But have you ever wondered where these measurements came from? It's a funny story, really. The US customary system, which includes cups, tablespoons, and teaspoons, has its roots in medieval England - who knew that baking had such a rich history?
In the old days, people used to measure ingredients with stars and moons - okay, not really, but they did use some pretty creative methods. For example, a "pinch" of salt was literally just a pinch between your fingers. Thankfully, we've moved on to more precise methods, like cups and scales.
So, back to our original question: how much is 3/4 cup of flour? Well, it's equivalent to 6 ounces or 170 grams. But what does that really look like? Imagine a small mound of flour - about the size of a baseball - that's roughly 3/4 cup.
