Mughal court cuisine, adapted and perfected in the Awadhi kitchen of Lucknow under the Nawabs; the Lucknowi korma tradition is defined by white and pale-gold preparations (safed korma) rather than dark or red sauces
Shahi korma (শাহী কোরমা — 'royal korma') is the Mughlai-Awadhi technique of braising meat in a cream and nut-paste enriched sauce that achieves palatial richness through the combination of fried onion paste (birista), cashew or almond paste, saffron, and yoghurt rather than through chilli heat. The technique is the exact opposite of the vindaloo school — aromatic complexity and fat-richness replace acid and heat. The nut paste forms the sauce's body; yoghurt provides tang and protein; the birista (caramelised-fried onions, properly पियाज बेरेस्ता) provides sweetness and deep Maillard colour.
Served with naan, roomali roti, or fragrant basmati. The sauce's pale gold colour signals restraint and luxury — a Mughlai table judgement where colour indicates the cook's restraint with chilli.
{"Birista preparation is where the korma lives or dies: onions fried in ghee until deeply golden-brown (not burnt) and ground to a smooth paste — this forms the flavour foundation","The nut paste (cashew or almond, soaked and ground to a completely smooth cream) must be introduced after the onion-spice base is established, not at the start","Yoghurt must be added cold, in small increments, stirring constantly — adding hot yoghurt in a single pour causes it to split and curdle","Low heat throughout — korma never reaches a rolling boil; a gentle simmer preserves the emulsion"}
A practitioner's test for korma doneness: the ghee should separate slightly and float on the sauce surface (called 'bhunao', भुनाओ — the oil-floating stage indicates that all moisture has cooked out and the spices are properly integrated). This is paradoxically the moment to stop — immediately after the ghee rises, add stock or water to bring the sauce to the desired consistency. Saffron bloomed in warm milk added at the very end gives the characteristic pale gold colour.
{"Burning the birista — bitter, dark-brown caramelised onion vs golden birista produces a completely different flavour; the colour is the cue","Adding yoghurt all at once to a hot pan — it curdles immediately; add cold, in tablespoons, with constant stirring","High heat — korma emulsion breaks at high temperature and the sauce separates into ghee and curdled yoghurt"}
