The most unique and memorable ice cream flavor I've tried has to be sweet corn. It sounds bizarre, but it was surprisingly delicious! The base was a rich, creamy custard infused with fresh corn kernels that provided amazing pops of sweet, vegetal flavor. Topped with a drizzle of honey, it tasted like summer in a bowl. While not a flavor I'd want all the time, it was such a fun and intriguing twist on a classic treat.
