Stuffed Cabbage Lumpia, Paw Paw Ponzu

STEP 1: PUFF THE BUCKWHEAT
Bring a small pan of water to the boil and simmer the buckwheat groats for 6-7 minutes until just tender, then drain very well and pat thoroughly dry. In a deep pan, heat the neutral oil to about 375°F (190°C) and fry the buckwheat in small batches until crisp and lightly golden — it will pop and puff. Lift onto paper towel and reserve the oil. Dry groats fry rather than puff, so the brief boil-then-fry is what gives the airy crunch.

STEP 2: BUILD THE CHILI CRISP
Return the reserved oil to medium-low heat and gently fry the sliced shallots and garlic until golden and crisp, then lift them out. Take the oil off the heat, let it cool for a minute, then stir in the chili flakes, soy sauce, sugar, and salt — it should sizzle softly, not scorch. Fold the crisp shallots, garlic, and most of the puffed buckwheat back in, reserving a little buckwheat to finish. Cool.

STEP 3: MAKE THE PAW PAW PONZU
Whisk the paw paw pulp with the soy sauce, rice vinegar, lemon (or yuzu) juice, mirin, and dashi until smooth. If using bonito flakes (katsuobushi), warm the mixture gently to just below a simmer, drop in the flakes off the heat, steep 5 minutes, then strain. Chill. The ponzu should taste bright and savoury with a soft fruit roundness behind it. Where paw paw is out of season, blend in ripe mango or very ripe banana for the custardy body, and reduce any added honey, as those fruits are sweeter.

STEP 4: MAKE THE APPLE BUTTER MOSTARDA
Whisk the apple butter with the white miso, both mustards, cider vinegar, and honey until glossy. Taste and balance — it should sit between sweet, funky, and sharp. Loosen with a little water if needed to a spoonable consistency.

STEP 5: PREPARE THE CABBAGE & FILLING
Carefully peel off the large outer cabbage leaves, blanch them for 30-60 seconds until pliable, refresh in iced water, and pat dry; shave down any thick central ribs so they roll smoothly. Finely shred a couple of inner leaves. In a hot pan with a little oil, stir-fry the garlic and ginger, add the pork and cook until no longer pink, then add the carrot, green beans, shredded cabbage, and spring onion. Season with soy sauce, toasted sesame oil, fish sauce, and white pepper. Cook until just tender and the mixture is fairly dry. Cool completely.

STEP 6: ROLL ONE LONG ROLL
Overlap the blanched leaves on a sheet of cling film or a sushi mat to form one continuous rectangle. Spread the cooled filling along the near edge in an even log and, using the film to guide you, roll up tightly into a single long cylinder, tucking as you go. Twist the ends to compact. Roll firmly but don't burst the leaves; a snug roll slices cleanly and holds its round cross-section. This is the move that let Rhoda feed 200 from one assembly line rather than wrapping individual parcels.

STEP 7: STEAM WHOLE, THEN PORTION
Steam the wrapped roll (still in the film, or transferred to parchment) in a cypress steamer over simmering water for 12-15 minutes until the filling is hot through and the cabbage is set. Rest a few minutes, unwrap, then slice across into rounds about 1 inch (2.5 cm) thick with a sharp knife. For a crisp finish in the lumpia spirit, sear the cut faces briefly in a little oil until lightly golden.

STEP 8: PLATE
Spoon a pool of chilled paw paw ponzu onto each plate. Set two or three cabbage rounds in the ponzu, add a quenelle or stripe of the apple butter mostarda alongside, and shower the buckwheat chili crisp over the top, finishing with the reserved plain puffed buckwheat for extra crackle. Serve at once.
