"Due to Southeast Asian influences and purple Okinawan sweet potatoes being a staple in Hawaii, vibrant violet desserts also thrive in the aloha state. Among other attention-grabbing options, downtown’s Wailua often offers a stunning ube version of shave ice, flavored with coconut milk and topped with fluffy ube foam and toasted coconut. Wailua has implemented pickup procedures, but online pre-ordering is a must." - Krista Garcia
