Aug. 5 is National Oyster Day, but for the oyster-obsessed, you don’t need a special day to appreciate these wonderfully briny delicacies. There are multiple types of oysters in season at any given time, and selecting them for home enjoyment can feel daunting, so oyster farmers Rob Knecht and Sims McCormick founded Real Oyster Cult, an online shopping experience for oysters and other shellfish delicacies. You can customize your order by oyster type, choose preselected bundles, as well as a monthly membership option. The oysters are shipped live via overnight delivery in insulated, chilled boxes to ensure freshness. Visit the eatery’s website to order: realoystercult.com.
