Which stores carry slender sticks?
On the East Coast and in the Midwest, most 4 oz. butter sticks are the long, slender kind, store brands included, so the butter at most grocery stores fits. You’ll typically find slender sticks at Publix, Wegmans, ShopRite, Stop & Shop, Giant, Food Lion and Harris Teeter on the East Coast, and at Kroger, Meijer, Hy-Vee, Jewel-Osco and Aldi in the Midwest. Also fits: Country Crock, Challenge, Danish Creamery, First Street, Medlee and Blue Bonnet sticks. On the West Coast, many store brands, including Sam’s Club Member’s Mark, use the shorter “stubby” stick, which doesn’t fit. Store names are a guide, not a guarantee: what each store carries varies by location and changes over time, so check that the stick is long and slender (about 4¾ in.) before you buy.
How our community cooks & bakes with The ButterBox™
It started at our family table. It's made for yours.
The ButterBox™ began in our own kitchen, while we were making crepes. Every crepe meant buttering a hot pan, reaching over the heat with a knife or a paper towel and too often burning our fingers. At the table, the shared butter dish picked up crumbs from every knife that touched it. For anyone with celiac disease or a gluten-free family member, those hidden crumbs mean cross-contamination at every meal.
So we designed something better. You slide the stick in with the wrapper still on and peel it back only as you use it, so the butter stays clean and covered. You hold the case, never the butter. The holder is heat-resistant to 325°F and the silicone lip to 400°F, so you can butter a hot skillet with your hand safely above the heat. And you spread straight from it, so no knife and no crumb ever touches the butter.
Dozens of prototypes later, tested by family, friends and neighbors, it became the first Au Cao® product: safer at the stove, safer at the table and easier for everyone.
