Add chopped white chocolate to a large heatproof bowl. Bring heavy cream, corn syrup, and butter to a boil in a saucepan. Pour hot cream mixture over chocolate, ensuring full coverage.

Combine water, sugar, and corn syrup in a medium saucepan. Stir to hydrate, then set over medium heat. Stir until sugar dissolves; as mixture becomes clear and bubbles, only swirl the pan. Brush down sides with a wet brush if needed. Monitor closely until caramel turns golden brown. Remove from heat, carefully whisk in cold butter one tablespoon at a time, followed by heavy cream, vanilla, and salt. Mix until smooth. Transfer to a heat-safe container and cool to room temperature. Refrigerate until firm.

Mix flour, cornmeal, sugar, and salt in a large bowl. Cut in cold butter and press into the mixture until pea-sized pieces remain. Combine ice water and vinegar; drizzle into the flour mixture, tossing until dough holds together but remains slightly crumbly. Shape into a disc, wrap, and refrigerate 30 minutes. On a floured surface, roll into a rectangle, fold into thirds, rotate, and repeat rolling and folding. Roll into a circle 5 cm larger than your tin. Line tin with dough, folding excess underneath and crimping edges. Refrigerate to firm before baking.
