The main difference between all-purpose flour and plain flour lies in their protein content. All-purpose flour has a higher protein content, which makes it perfect for baked goods that need to rise, like bread and cakes. Plain flour, on the other hand, has a lower protein content, making it better suited for delicate treats like cookies and pastries.
But here's the thing: plain flour can still be used in place of all-purpose flour in a pinch. It's like using a different type of fuel for your car - it might not be the most efficient, but it'll still get you where you need to go. Just be aware that your final product might be slightly different in terms of texture and consistency.
Think of it like a flour spectrum - with bread flour on one end, cake flour on the other, and all-purpose flour and plain flour somewhere in between. Plain flour is more like a middle child - it's not as strong as bread flour, but not as light as cake flour either.
