Some of you know it as the aliquot jar. Same trick, less intimidating name. Take a small piece of your dough at the start of bulk, drop it in a clear jar, mark the starting line, and let it sit right next to your main bowl. That little jar tells you what's happening inside your big batch without you having to guess.
Here's the part most people miss: you're not waiting for the dough to double. You're watching for halfway. Roughly a 50% rise on the jar.
If you let it hit double, you've already overshot. The dough kept fermenting past peak, the gluten structure started breaking down, and the loaf you bake is going to read flat, gummy, and dense even though you swore you followed the recipe. This is why so many of you have been fighting tight crumb and disappointing oven spring.
The fix is simple. Watch the jar, not the clock. Pull when it's halfway up.
Watch the lesson, grab a jar from your cabinet, and try it on your next bake. Drop a comment when you do. I want to see your before and after.
