Cherry for me, my grandma would always have it and it was always delicious.
(I ask this as I am eating cherry ice cream)
Spumoni. They even make that anymore. Probably only in the Mediterranean area.
Boysenberry. It’s weirdly become very rare at least where I live. It used to be quite common
Hokey Pokey ice cream. It’s a vanilla ice cream with honey comb pieces inside of it. I’m positive that most kiwi kids would answer the same way. A close second is boysenberry ice cream.
Pumpkin or peach ice cream has the strongest childhood association for me—a place by the highway sold it fresh & seasonally. These aren’t common flavors either.
Young coconut ice cream. It’s one of those flavors we can easily get from those ice cream carts that stop by the neighborhood usually in the middle of the afternoon. There’s also mango and avocado completing the usual three flavors the cart would have, and I would always buy all three flavors available (unless I really hate the flavor).
Some of the adults would opt to have the ice cream served in a bread bun (usually just repurposed hamburger buns, without the sesame seeds), but I always opted for the sugar cones.
