Lúcuma: Tastes like caramel and chocolate together, but it comes from a fruit. Apparently it's quite healthy. Great flavor for ice cream, liqueurs, cakes, and candies. I discovered this flavor in Chile.
Ube/taro: This purple yam tastes like purple. The color is the best. I guess it tastes nutty/starchy/sweet. Can be used in savory dumplings, but it truly shines in ice cream, cakes, candies, and the like. I discovered this flavor from my Filipino roots.
Achiote: Very complex flavors of citrus, tequila, chile, zestiness. This is a poor man's saffron (for the color, not the flavor). I discovered this flavor from my Mexican roots. Good for marinating fish, any kind of meat, and seafood. I want to explore this with vegetarian dishes too. Also a great natural dye for foods and cosmetics.
Horchata: This is a Mexican rice drink flavored with sugar, vanilla, and cinnamon. Can also be made with other seeds and nuts like almonds, but the result is always delicious.
