Songpyeon — Half-Moon Rice Cake with Sesame and Chestnut Filling (송편)

Combine the wet-milled fresh rice powder (쌀가루) with fine salt in a large bowl, then add just-boiled water in a thin stream — pouring slowly lets you feel the dough tighten gradually rather than seizing in uneven lumps — mixing with a wooden spoon and then kneading firmly by hand until the dough is smooth, pliable, and does not crack at the edges when pressed flat. The dough is ready when it bends without splitting and holds a clean impression of the fingertip.

Mix the toasted, lightly crushed sesame seeds with honey, then combine the crumbled cooked chestnuts with honey in the same manner, working each filling until it clumps cohesively, so it can be tucked into the dough as a compact unit rather than scattering when you fold. Each filling should hold its shape when pressed between the fingers and not flow freely.

Pinch off a piece of dough approximately 25 g and press it flat in the palm into a round disc no thicker than 4 mm, with edges slightly thinner than the centre so the seam, which bears the most stress during steaming, has the same wall thickness as the rest of the shell. Place a filling portion no greater than 40% of the total volume at the centre — this is where the dish lives or dies: overfilling causes the songpyeon to burst during steaming as the filling expands, and the rice wall must dominate the cross-section. Fold the dough over the filling into a half-moon and press the seam shut with a firm, rolling pinch along the entire edge, leaving no gap; a thin, even crescent is the mark of practiced hands.

Line the steamer basket with a dense, even layer of rinsed fresh pine needles — rinsing removes surface dust without stripping the resin, which carries the fragrance into the cake's skin during steaming — then arrange the shaped songpyeon in a single layer on the pine needles, none touching, so steam can circulate freely around each piece. Bring the steamer water to a full boil, place the basket over it, cover tightly, and steam for 20–25 minutes; at the end of the cooking time the songpyeon will be translucent at the edges and yield softly to a gentle press without springing back.

Remove the songpyeon from the steamer and immediately toss lightly with a very small amount of sesame oil so the surface stays glossy and the cakes do not bond together as they cool. Serve warm; the surface should be tender and carry a clear pine fragrance.
