A celebrated South Indian sweet made from roasted chickpea flour, caramelized sugar syrup, and generous amounts of ghee. It has a rich, melt-in-the-mouth texture infused with aromatic cardamom.
Lightly grease a 5 cm (2 inch) deep rectangular tray or dish with a little ghee and set aside.
Combine 400 g granulated sugar with 250 ml water in a large, heavy pan. Warm over low heat, stirring constantly until the sugar completely dissolves, then raise the heat to bring it to a boil. Skim off any surface scum with a slotted spoon and boil until the syrup forms two to three threads when tested between your fingers. Mix in 2.5 g lime juice and the cardamom spice, then take the pan off the heat.
Bring 500 g ghee to a boil in a separate heavy saucepan, then immediately take it off the heat.
Place a second large, heavy-based pan over low heat and ladle in 100 g of the hot ghee. Stir in 175 g chickpea flour and 65 g plain flour, toasting the mixture for roughly 5 minutes until the fat begins to separate from the flour.
Pour in the hot sugar syrup and stir vigorously for 1 minute. Keep stirring while incorporating the remaining hot ghee one tablespoon at a time, until the mixture pulls away from the spoon and stops sticking.
Tip the mixture into the prepared tray and leave it undisturbed for 5 minutes to settle. Carefully tip the dish to pour off any unabsorbed surface ghee, cut into 5 cm (2-inch) squares, and allow to cool to room temperature before serving.
Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.
For crisping batters or binding cutlets: use 50% to 60% of the weight. Produces a very crisp shell but lacks the earthy, roasted nutty flavour of besan.
