Cantonese Steamed Silken Tofu with Preserved Egg (Pi Dan Dou Fu Advanced / 皮蛋豆腐进阶)

Ingredients

• 600 g block silken tofu, drained on clean cloth in the refrigerator for at least 2 hours until slightly firmer but still silken
• 2 premium century eggs (pi dan), refrigerated until very cold; select eggs showing snowflake (song hua) crystal pattern in the white; smell before purchase to confirm absence of ammonia off-notes
• For the dressing
• 2 tbsp light soy sauce or fish-flavoured soy (steam soy)
• 1 tbsp toasted sesame oil
• 1 tsp aged black vinegar, a few drops only; applied last before garnish
• 1 tsp chilli oil
• For the garnish
• 1 tbsp white sesame seeds, toasted
• 3 tbsp neutral oil, for frying garlic chips and shallot
• 4 cloves garlic, very finely sliced into chips
• 2 shallots, very finely sliced
• 2 spring onions, green parts only, finely sliced

Method

1. 1
   Place the silken tofu block on a clean cloth set over a rack. Fold the cloth over and refrigerate for a minimum of 2 hours. The tofu is ready when the cloth shows clear moisture absorption and the block holds its shape when the cloth is peeled away without weeping visibly onto a dry plate.
2. 2
   Fry the garlic chips in neutral oil over a medium-low flame, stirring constantly. Remove the moment they turn pale gold — they continue to colour off the heat. Drain on paper. Repeat with the shallot slices. Both should be crisp and dry, not soft or bitter.
3. 3
   Shell the century eggs while they are still very cold from the refrigerator. Rinse briefly and slice cleanly with a thin wet knife. The snowflake crystal pattern in the translucent white confirms premium grade; the yolk centre should be dark jade-grey and set. Warm eggs resist the blade and lose their dramatic cross-section — cold is essential here.
4. 4
   Unmould the drained tofu onto a chilled serving plate. Arrange the century egg slices over and around the tofu. This is the step on which the dish lives or dies: the tofu must carry no pooled water beneath it and the dressing must meet a dry surface — any residual moisture from insufficient draining will dilute the dressing and render the dish irretrievably soggy.
5. 5
   Apply the dressing in strict sequence. Spoon the light soy or fish soy over the tofu and egg first. Follow with the sesame oil. Add a few drops of aged black vinegar. Finish with the chilli oil. Each layer should be visible as a separate pool before the dish is brought to the table — tasting at this stage, the dressing should read clean-savoury, sesame-rounded, and just brightened by the vinegar without any single element dominating.
6. 6
   Scatter the toasted sesame seeds, fried garlic chips, fried shallot, and spring onion greens over the surface. Serve immediately at a slightly chilled temperature — below 10 °C suppresses the layered flavour; the dish should be cool to the hand but not ice cold.
