Indian mithai (मिठाई — sweet, sweets, confection) encompasses hundreds of regional preparations unified by a common technique at their foundation: the reduction of milk. Full-fat buffalo milk (or cow's milk in many regions) is cooked in a wide, heavy pan (a kadhai) over sustained heat, stirred continuously, until it loses 50%, 60%, 70%, 80% of its volume — the degree of reduction producing different materials with different properties. This reducing-milk system has no parallel in any other confectionery tradition and produces textures and flavour compounds that no other technique can replicate. The Maillard reaction between milk proteins and lactose during prolonged heat produces a flavour that is simultaneously caramel-sweet, slightly grainy, intensely dairy-rich, and faintly savoury — the foundational flavour of most North Indian mithai.
The reducing-milk products, in order of progressive reduction:
1. Wide pan, high heat, continuous stirring — the wide pan maximises evaporation surface; the high heat accelerates reduction; the continuous stirring prevents the protein solids from scorching at the base 2. The colour change as progress indicator — fresh milk is white; at 50% reduction it is cream; at 75% it is the colour of pale caramel. The progression is visual. 3. The scraping technique — as the milk reduces and solids form at the sides and base of the pan, these solids are continuously scraped back into the liquid mass. The solids ARE the khoya — they must not be discarded or they will scorch. 4. Full-fat milk mandatory — skim or low-fat milk produces insufficient solids for the reduction to yield any useful product Sensory tests: - **The palm test for khoya:** Take a small piece of finished khoya and roll it between the palms. It should form a smooth ball without sticking to the palms and without crumbling. Sticky means too much moisture remaining. Crumbling means over-cooked (the fat has separated from the protein matrix). - **The taste:** Khoya should taste of deeply caramelised dairy — sweet, with a slight savouriness from the milk proteins. If it tastes of raw milk, reduction was insufficient. If it tastes burnt, the stirring was inadequate. - **The burfi set:** Correctly made burfi, spread and set (20–30 minutes at room temperature) cuts cleanly with a knife — neither crumbling nor smearing. Press a piece with a thumb — it should hold the impression rather than springing back.
