The answer, of course, is: It’s both!
Look at this oversized measuring cup from King Arthur Flour’s Baker’s Store. It’s a 3-cup measure, which is actually very handy for measuring out large quantities of flour for big batches of bread and cookies (if you’re not using a scale, of course).
But it also does double-duty as a teeny-weeny saucepan, and we can think of a lot of uses for it!
