On the same day we will prepare caramel sauce. To do this, take sugar (225 g), heavy cream and butter. It’s more convenient for me to cook it in a frying pan. Pour the sugar into the mold in an even layer on the bottom and put on medium heat. Shake as it melts to avoid burning. In parallel, bring the cream to a boil. When the sugar has completely melted and acquired a uniform amber hue, carefully pour in the hot cream. Mix quickly with a silicone spatula. CAREFUL, IT SPLASHES AND BOILS! Do not use a spoon for mixing – the mass will curdle from the temperature difference. Pour a homogeneous, slightly cooled mass into a glass.
