• 5 ml white vinegar

Method

Chilli crisp is a finishing-sauce built on one principle: controlled temperature shock. The aromatics steep in oil to release their volatile compounds, then that infused oil hits a spice bed hot enough to bloom the chilli powder and toast the sesame, but not so hot it burns either to bitterness. The acid and sugar arrive last, as counterweights to heat and sharpness.

Start by infusing the oil. Heat 150 ml peanut oil in a wok or heavy pot over a medium flame. Add the star anise, Sichuan peppercorn, bay leaves, white cardamom, cardamom, ginger slice and spring onion. You're looking for the moment when the aromatics darken slightly and the oil smells layered — funky, toasted, alive — roughly 8–10 minutes. The spices will keep darkening off-heat, so pull them when they're just short of where you want them. Strain through a fine sieve; discard the solids. This is aromatic-infusion: the oil carries the flavour compounds forward while the fibrous plant matter falls away.

While the oil cools to exactly 210°C (use a thermometer; this temperature is not negotiable), assemble your spice bed in a ceramic or heatproof glass bowl. Combine the dried chilli powder, toasted sesame seeds, minced garlic, minced bird's eye chilli, salt, five-spice powder and cardamom. The heat of the incoming oil will wake every component — the cardamom's cool floral notes will unfurl, the Sichuan peppercorn will activate its numbing compounds — but only if the oil arrives at the right temperature. Too cool and the mixture stays muted; too hot and you'll scorch the chilli to acrid char.

Pour the hot oil in a slow stream, stirring constantly. The friction and heat will raise the temperature of the spice mixture above the oil's own temperature through spice-blending action — expect vigorous bubbling and visible oil darkening as this happens. Once the vigorous phase settles, add the white vinegar. The acid will cut the richness and sharpen the chilli's bite; the mixture will bubble again. Let it cool to blood-warm, then stir in the sugar. Sugar mellows heat not by coating the mouth but by competing for the same taste receptors, and it rounds out any harsh peppery edges that remain. Taste before jarring. If the heat still dominates, add a little more sugar in quarter-teaspoon increments. Store in a sealed jar — the oil will set slightly as it cools, which is correct.
