A treacle tart made with golden syrup and jaggery in a crisp pastry case, with a breadcrumb-thickened filling and a smooth milk ice cream. It is sweet and slightly smoky, with a pinch of sea salt to balance it.
Soak 2.5 g gelatine sheet in cold water until soft.
Pour 750 ml of the 828 g whole milk into a heavy-based saucepan, keeping the rest back. Add 75 g caster sugar and stir constantly over medium heat; simmer until reduced to 500 ml.
Lower the heat and stir in 130 g condensed milk and 10.4 g glucose.
Squeeze the soaked gelatine sheet and stir it into the warm milk mixture until dissolved.
Stir the reserved whole milk into the mixture, then cool completely.
Churn in an ice-cream machine for 15–20 min, until thickened. Transfer to a freezer-proof container and freeze.
Rub 110 g unsalted butter into 225 g plain flour until lightly crumbed.
Add 50 g egg and mix, then bring together by hand to a smooth dough, adding 1 tbsp water if it feels dry.
Shape the dough into a ball, flatten to a disc, wrap in cling film and refrigerate for 20 min.
Heat the oven to 160°C (320°F/Gas 3) and grease a 23 cm (9 in) flan ring.
Roll the dough on a lightly floured surface, using extra plain flour for dusting, to about 5 mm (¼ in) thick, and line the flan ring.
Line the pastry with baking parchment and baking beans, then bake blind for 20 min.
Remove the parchment and beans and let the case cool in the flan ring.
Lower the oven to 150°C (300°F/Gas 2).
Put 280 g golden syrup, 100 g jaggery, lemon juice to taste and 100 g egg in a heavy-based saucepan over low heat and melt together.
When incorporated, stir in 99.4 g double cream.
Remove from the heat and fold in 200 g brown breadcrumbs.
Pour the mixture into the pastry case and bake for 45 min, until set and golden.
Remove from the oven and cool.
Sprinkle himalayan sea salt to taste over the cooled tart and serve with the milk ice cream.
Use 80% of the weight. Granulated sugar is sweeter by weight, but gives a cleaner, one-dimensional sweetness that lacks jaggery's caramel, molasses depth.
Soak and blend into a paste; use 100% to 120% of the weight. Adds rich, natural, fruity sweetness with complex, dark molasses notes that thicken the gravy.
For binding, use about 10 g chickpea flour mixed with 20 ml water per egg and rest for 10 minutes. Denser and nuttier; not suitable for baking or coating in the same way.
For 100 g condensed milk, whisk 30 g milk powder with 40 g sugar, 30 g hot milk or water and 5 g butter until smooth. It will be slightly less glossy but works in sweets and curries.
For 100 g condensed milk, simmer 250 g full cream milk with 75 g sugar until reduced to about 100 g, stirring often. Takes 20–30 minutes and gives a fresher, less caramelised flavour.
