Lahpet Thoke (Fermented Tea Leaf Salad)

Variations

• Lahpet thoke and lahpet yay: thoke is the mixed salad; the formal service keeps the components in separate heaps. Lahpet is what Myanmar offers a guest and what is served to close a dispute, so at a formal table it arrives in a compartmented lacquer box (lahpet ok) with each element apart.
• Sweet and sour lahpet: a short ferment packed in oil is mild; a long one is sharply sour. Many commercial jars come already dressed with garlic and oil, so taste before you add the step-3 seasoning and cut it back if needed.
• There is no substitute for the leaves. A green tea bag or the leaves left in a pot will not do. Brewed leaves are what remains after the tannin and caffeine have gone into the water; lahpet keeps both in the leaf and changes only how they are bound. It is not a matter of degree.
• The other thokes: Burmese salads are named ingredient + thoke — nan gyi thoke (rice noodles), kauk swe thoke (wheat noodles), thinbaw thee thoke (papaya). The architecture never changes: one soft principal ingredient, many crunchy ones.
• Vegetarian: drop the fish sauce and dried shrimp and use soy sauce and toasted bean powder. The salt comes back but the savour is shallower, so lengthen the lime a little.

Tips

• It is the third way of dealing with tannin. Acorn jelly leaches it out over days with changes of water and throws the water away; dried persimmon dries it until the tannins are linked into molecules too large to grip saliva protein. Lahpet ferments it — microbes and months break the astringency down and leave lactic acid and amino acids where it was. Of the three it is the only one that adds flavour instead of removing it.
• No brine is poured in. The pressing makes the liquid. Fermentation basics gives keeping air out as "pressing everything under the liquid", and lahpet starts with no liquid at all. Steamed leaves go into a bamboo cylinder or a jar under a heavy stone, the leaves give up their own juice, and that juice becomes the brine. Pressing is both the anti-air measure and the way the liquid is created. Takuan answers the same problem with a bed of dry rice bran and paocai with a brine handed down for years. Three different answers.
• Why steaming comes first. Left alone after picking, tea leaves oxidise by their own enzymes and become black tea. Steaming kills those enzymes so the green colour and the grassy note survive, and from that point on it is the microbes' work. It is the first step in making green tea, pointed at a different destination.
• The crunchy things are structure, not garnish. The leaves are soft, strong and damp. On their own you tire of them in two spoonfuls. Halo-halo makes the same argument — that contrast matters more than the number of components — but here the contrast runs one way only: one soft thing against six crisp ones.
• Do not mix it in advance. It is the only way this dish fails. Fried beans start drinking the moment they meet lime juice. Serving temperature sets out the dishes with no grace period; this one is in the same position for moisture rather than heat.
• It contains caffeine. Lahpet thoke has more of it than a cup of brewed tea, and in Myanmar it is eaten by students working through the night and by long-distance drivers. It is the only dish here whose stimulant effect is part of the point, so two platefuls late in the evening will do what you would expect.
