Do you know this leaves?
We call Pandan Leaves by Lá Dứa in Vietnam.
They have a grassy herby flavor and can be tied in a knot and added to rice, both long grain and sticky rice. Cooks also use them in desserts by extracting their liquid, traditionally done by pounding on the leaves but I do it in the blender or mini-chopper with a little water. The green result is striking in color, kind of like super wheat grass in smell and looks. Once cooked, the color turns to a celadon green, and there’s a subtle hint of the herby quality.
