Klepon belongs to jajanan pasar, the morning market snacks sold from glass cases in Java and across the archipelago. They arrive on a banana leaf, three or four to a portion, and the whole point is the moment the shell gives way and hot palm sugar floods your mouth.
Eat them with your mouth closed. Everyone learns this the hard way once.
Sealing is the whole recipe
A leak means the sugar escapes into the water and you are left with a plain rice ball. Pinch the seam properly, roll the ball between your palms until you cannot see the join, and check for hairline cracks before it goes into the pot.
Dough that cracks while you shape it is too dry. Add pandan water a teaspoon at a time until it stops fighting you.
On the colour
Real klepon get their green from pandan leaf, not food colouring, so the shade is muted and slightly grey rather than bright. Blend the leaves with water, strain, and use the liquid warm. The colour fades a little during boiling, which is normal.
Klepon are best within a few hours of making. The glutinous rice hardens overnight, and reheating never quite brings them back.
