As tradition built it

Makes about 20 sheets. About 1 hour, plus soaking.

Ingredients

An outline, not yet a recipe: the tradition's method with its ingredients named but not weighed. Quantities are being added from sources inside the tradition, lead dishes first.

• 500 g old-crop rice flour, or ground old-crop rice
• water, to a thin batter
• 200 g minced pork, 50 g wood-ear fungus, mushroom to taste minced pork, wood-ear fungus, mushroom (if filling)
• to serve fish sauce, chả, fried shallot, to serve

Method

1. Soak the rice 2 to 3 hours; old-crop rice, not new-harvest, is specifically chosen to avoid a gummy finish.
2. Grind to a thin, smooth batter.
3. Stretch a cloth tight over a pot of boiling water at exactly 100°C. Ladle a thin, even layer of batter across the cloth.
4. Lift the sheet the moment it begins to puff, the hardest judgement in the whole dish: it must cook through evenly while staying chewy rather than mushy.
5. If filling, spoon minced pork, wood-ear fungus and mushroom onto the sheet before it sets, and roll.
6. Serve plain, or filled, with fish sauce, chả and fried shallot.

What a modern chef changes

The steam environment controlled, not just the pour

No named rung; a precision discipline this chapter treats on its own terms

Method

1. Hold the water at a genuine, steady 100°C rather than a rolling boil that fluctuates, since inconsistent steam is what most often causes an uneven sheet.
2. Practise the lift on a few sacrificial sheets before committing to a batch, since the "moment of puffing" is a judgement call that improves with repetition and is not reliably describable in words alone.
3. If filling, have the filling fully cooked and warm before the sheet goes on, so the sheet itself only needs to hold its shape through the roll, not finish cooking anything inside it.
