Thompson traces panang to Persian and Malay culinary influence reaching Siam through maritime trading routes — the peanuts in the paste and the relatively thick, reduced preparation share characteristics with Malay-influenced southern Thai preparations. [VERIFY: Thompson's specific etymology for 'Panang' — connection to Penang disputed]
A thick, reduced curry with a rich, slightly dry coconut cream sauce that clings to the protein rather than pooling around it — the most compact and intensely flavoured of the central Thai curries. Panang curry is characterised by its paste's inclusion of roasted peanuts (ground into the paste), its minimal liquid (the finished curry is almost dry, the sauce coating the protein with a thick, rich layer rather than forming a pool), and its characteristic garnish of shredded kaffir lime leaves and thinly sliced fresh chilli laid on the surface at service. It is the most richly concentrated of the classical Thai curry family.
**Panang paste:** - Red curry paste base (Entry T-05) plus: dry-roasted peanuts (ground to a paste in the mortar — a tablespoon of roasted peanuts pounded smooth until they become a paste, the oils released, the texture smooth). The peanut paste is incorporated into the spice paste and changes its texture, making it denser and richer. - Additionally: coriander seeds and cumin in higher proportion than standard red curry paste. **The preparation:** 1. Crack the coconut cream (Entry T-03). Add the panang paste. Fry for 4–5 minutes. 2. Unlike green or red curry: do not add additional liquid beyond the initial coconut cream. Panang is made with the paste fried in the cracked cream and then the protein added to this thick, rich base. 3. Add the protein — thinly sliced beef (the classic panang neua) or chicken. 4. Add coconut milk very gradually — just enough to coat the protein and bring the curry to a thick sauce consistency. The finished panang should have a sauce so thick it clings to the back of a spoon and barely flows. 5. Season with fish sauce and palm sugar. The panang balance leans toward sweet — more palm sugar than red or green curry. 6. Finish with kaffir lime leaves, chiffonaded extremely fine (stacked and sliced into the finest possible strips — they are eaten, not merely infused). 7. Lay thinly sliced fresh red chilli on the surface. 8. A drizzle of coconut cream at service. Decisive moment: The coconut milk addition — adding it very gradually and checking consistency between additions. The panang should arrive at the correct thick, clings-to-spoon consistency before any more liquid is added. Adding too much coconut milk at once produces a curry that cannot be reduced back to the correct thick consistency without losing the paste's aromatic compounds to prolonged high-heat reduction. Sensory tests: **Sight — the finished consistency:** A spoon drawn through panang should leave a clean line on the surface that closes slowly — the sauce flows toward the line but does not immediately fill it. This is the 'clings-to-spoon' consistency. Compare to: green curry, which flows freely and fills the spoon-trail immediately. **Taste:** Panang has the deepest, richest flavour of any Thai curry: the peanut in the paste adds a roasted depth that other curries lack; the thick coconut sauce amplifies the fat-carried aromatic compounds. The sweetness is prominent — palm sugar is more present than in red curry. The heat is moderate and builds slowly. **Smell — the kaffir lime chiffonade:** Kaffir lime leaves sliced into very fine strips release their essential oils (primarily citronellal and linalool) from their cut edges. The smell of freshly sliced kaffir lime leaf at service is one of the most vivid in the Thai kitchen — citrus-floral, intensely aromatic, and brief (the volatile compounds begin to dissipate within minutes of cutting).
— **Liquid curry, not thick:** Too much coconut milk added. Reduce over medium heat until the oil separates around the paste and the sauce thickens. — **Kaffir lime leaves that are too thick and tough to eat:** The leaf was not chiffonaded finely enough. The leaves should be paper-thin — 1mm or less. Any thicker and the leaf's texture is unpleasant.
