Progressive International PKS-300 Powdered Sugar ProKeeper, Plastic, Clear

Product Information

You don’t have to be a top chef to know how important it is to cook with fresh ingredients. Far too often, though, pantry staples like flour and sugar get improperly stored, making them prone to spoiling or going stale. Whether you bake daily or only tie on an apron during the holidays, the best airtight containers for flour and sugar will keep your ingredients fresh and ready for use. To help you weigh your options, here are a few things to keep in mind when shopping. Our Lab team consists of testers with decades of experience in both professional and home kitchens. In addition to their testing, these sets were sent out to our food and commerce editors, who cook and meal prep consistently. We found a 1-cup dry measuring cup can easily reach all the way to the bottom of the large, 114-ounce container. The wide opening at the top (and the equally wide shape of the rest of its base) make scooping and sweeping easy to execute. This container is meant to be washed only by hand with warm, soapy water and a nonabrasive cloth or sponge to avoid scratching.

Product-specific design wins again with Progressive’s 4.5-quart cereal dispenser. It has a spout for easy pouring and holds a family-size box of cereal. The container is made of food-safe, BPA-free plastic and boasts an airtight silicone seal to ensure freshness. Like other Progressive products, this one is designed for vertical storage to optimize space in your pantry, and it is dishwasher safe. Each spice jar features a wide mouth to accommodate various measuring spoons. They’re food-safe, and the lids are BPA-free, designed with optimal freshness in mind. Spices can lose their potency when exposed to air, so having airtight storage at the ready is doubly important, and we loved how well these little jars sealed—especially since they are so easy to open, too. Whether grinding your own spices, buying in bulk, or purchasing from a grocer, these containers provide a chic, uniform, and tight seal for a plethora of herbs and seasonings. We also conducted a test storing an onion and tomato mixture in this container and found that there were no streaks on the plastic and detected only a faint aroma of onion. Design-wise, the comfort of having an ergonomic spot for the hands with this container is a win. We also appreciated that there were two different openings, one to fill the container and another to pour out the cereal.

Rachel Werner, who updated this article,is a culinary writer who has been profiling farmers, chefs, restaurants, and food-based businesses for more than seven years. Her work has appeared in a variety of regional and national publications, such as TheKitchn, Fabulous Wisconsin, BRAVA, and Hobby Farms. Rachel personally tested eight dry food storage containers for this list. We suggest occasionally hand washing to clean between the grooves of the lid. The rest of the container can go in the dishwasher. We noticed and were impressed by how these glass food storage containers stayed fresh even after the tomato-onion stain and smell test. The containers can hold liquids, but we don't recommend having liquids inside for too long because the lids are not supposed to be wet for a prolonged period of time. Although the lids are meant to be hand-washed, we found that they endured just fine through a run in the dishwasher. Capacity: We noted whether any of the sets included containers with varying sizes and whether the mouth of the containers could accommodate tools like measuring cups for scooping.

Cleanup: We washed the containers, both by hand and in the dishwasher, and noted any damage to the bases or lids after washing or nooks and crannies that retained food particles.

A variety of dry measuring cups will fit inside this container without difficulty, and there is an included lever that can be inserted just below the top of the container to level off scoops before removing from the container. This product is safe to store in the freezer, and it is dishwasher safe, too. Also, note that the containers did not pass the shatter test—when pushed onto the floor from the counter, they completely popped open and contents spilled everywhere. For those looking to save space or invest in something a little more budget-friendly, look for a safe, recyclable plastic option. If you want something sustainable that adds style to your kitchen while storing goods, consider glass or ceramic.
