Sichuan Chilli Oil
Hot oil poured over chilli flakes and spices in stages, so the sediment toasts without burning. Fifteen minutes, and it improves everything for a month.

-
Put the chilli flakes, sesame seeds, salt and sugar in a large heatproof bowl and stir.
-
Heat the oil with the onion, ginger, spring onions and all the whole spices over medium-low heat 15 minutes, until the aromatics are golden and the oil smells strongly of them.
-
Strain the oil and discard the solids. Return the oil to the pan.
-
Bring the oil to 190C — a chilli flake dropped in should sizzle vigorously.
-
Pour a third of the oil over the chilli flakes and stir; it will foam and smell toasty.
-
Let the oil in the pan drop to about 160C, then pour over another third and stir.
-
Let it drop again to about 130C and pour over the last third.
-
Stir well, cool completely, and pour into a clean jar with all the sediment.
-
Leave 24 hours before using — the colour and flavour deepen overnight.
Chef’s Tips
- Three pours at three temperatures. One pour scorches the top.
- Coarse flakes, never powder.
- Keep the sediment. It is most of the flavour.
Common Substitutions & Variations
- Out of spring onions? A small regular onion, finely sliced, or a few chives stirred in at the end both cover the job.
- A quarter-teaspoon of ground ginger per tablespoon of fresh is the standard ratio if you are working from the spice rack rather than a fresh root.
Pairing Suggestions
- Wontons
- Cold noodles
- A fried egg
Storage & Reheating
In a sealed jar at room temperature for 3 months, or refrigerated for 6.
