10 Jun 2025
This playful, high-contrast bite from Executive Chef Ollie K.C. Liedags of Hilda and Jesse flips the classic avocado toast on its head. Instead of bread, tempura-battered sweet potato delivers crunch and sweetness, topped with a nostalgic sour cream and onion dip, creamy avocado, and a zippy finish of dill and fresh horseradish.
