Combine the minced meat with the ground makhwaen, dried chilli, and dried galangal, working the spice powder thoroughly into the meat so that every particle of mince is coated and the seasonings will penetrate evenly rather than sitting only on the surface. Season with fish sauce and salt. The meat should smell sharp, resinous, and aromatic before it touches the pan.

Set a wok or heavy pan over high heat and add no oil, so the meat is forced to render its own fat and fry in it rather than stew in an added medium. Place the spiced mince directly into the dry pan and begin pressing and spreading it across the surface — the fat will begin to render immediately, and this is the only fat the dish will use. The meat will sound wet at first, then progressively drier and more crackling as the moisture drives off; listen for this transition.

This is where the dish lives or dies. Once caramelisation begins — the meat will colour and the fat will appear to fry rather than steam — stir constantly and without pause, keeping every particle moving so nothing scorches while the rest finishes. Do not add water if the meat sticks; lower the heat fractionally and continue moving instead, because water at this stage returns the pan to steaming and collapses the caramelisation already built. The meat must become fully dry, crumbly, and deeply browned with the spice powder caramelised into each particle, and the smell will shift from raw rendered fat to a concentrated, toasted, roasted character; taste now for salt and heat, because larb khua without sufficient makhwaen and dried chilli lacks its defining character.

Remove from heat when the mixture is visibly dry and crumbly with no moisture remaining and no steaming rising from the pan, so any residual steam still present would carry on softening the crust you have built. The colour should be a deep, even mahogany. Press a small amount between finger and thumb — it should feel dry and granular, not paste-like or greasy.

Transfer to a serving vessel and, for a variation, mix through fresh shallot slices or fresh herbs at this stage only, so the heat of the meat barely wilts them and they retain their raw bite against the deep roasted mince. Serve in small quantities alongside sticky rice. The finished larb khua will keep 2–3 days at room temperature or one week refrigerated.
