Cambro 2 QT Round Transparent Food Storage Container - BPA-Free Plastic, Airtight Lid for Freshness - Ideal for Meal Prep, Leftovers, and Commercial Kitchen Use

I like to bake sourdough bread. Judging the amount of rise is critical. Judging the rise in a mixing bowl is nearly impossible. With these basically straight sided containers and the markings on the side, judging the rise is a no-brainer. Their low profile and fairly small diameter make them perfect for me to have two loaves rising in my proofing box at the same time.My sourdough bread has improved significantly since I started using these containers.
