2Spread the almonds out on a small rimmed baking sheet and roast in the oven for 5–7 minutes, until lightly browned. Set aside to cool. Line two large rimmed baking sheets with parchment paper and set aside.
3Place 1/4 cup/50 g of the sugar in a small saucepan with the water and stir to combine. Cook over high heat for about 4 minutes, until it has turned a light golden brown; do not stir, just gently shake the pan to help the sugar dissolve. Add the almonds and cook for 1 minute, so the nuts are coated and the caramel turns dark, without burning. Pour the mixture onto one of the lined baking sheets and set aside until cool.
