Smooth Chocolate Biscuit Sauce for Desserts

Place the milk, butter, chocolate, vanilla, and salt in a cold saucepan, then stir gently until the ingredients are evenly distributed.

Heat the mixture over medium heat, whisking constantly, until the milk is hot, the chocolate and butter have completely melted, and the mixture is smooth.

Gradually add the tea biscuits over medium heat, stirring gently until incorporated into the hot mixture with no large lumps.

Continue stirring the sauce over medium heat, scraping the bottom of the saucepan, until it thickens and begins to boil.

Remove the saucepan from the heat as soon as the sauce begins to boil and reaches a thick, smooth consistency to prevent it from becoming too thick.

Cover the surface of the sauce directly with plastic wrap, pressing it gently so it touches the entire surface and prevents a skin from forming. Leave the sauce undisturbed on the counter until it stops steaming and cools completely.

Blend the cooled sauce in a blender or with an immersion blender until all lumps disappear and it becomes smooth, glossy, and silky.

Pour the smooth sauce over chilled desserts, spread it evenly, and serve immediately while it is silky.
