Growing up in the US I have used cups in measuring dry ingredients and have never used anything else. But in using various cookbooks, weight measurement has come up a lot. Using a scale to measure dry ingredients is much more accurate and precise. I, however do not possess a scale and thought I knew the conversion when I made this brioche. I did not. After rising the dough for the first time, I realized it looked more like a batter than a dough and there was no way I could knead it properly. Apparently 16 oz of dry ingredients is the equivalent to about 4 cups. Don't make the same mistake I did and think that one cup is 8 oz! Thankfully this mistake was easily fixable and I just kneaded the extra cup of flour that I needed. Find a good recipe and try this bread, it's one of my favorites! Makes me feel like I'm in Paris again!
