To serve: sliced bread rolls and butter, for frying
Directions
Pour the milk into a medium saucepan over medium-low heat. When it comes to a boil, turn off the heat.
Add the butter and stir until completely melted. Add the salt and sugar and blend thoroughly with an immersion blender (or transfer to a countertop blender).
Add the strained lemon juice and mix until the mixture curdles – that is the right consistency.
Strain the mixture through a sieve, then chill in the fridge for at least 3 hours.
To serve, slice a bread roll, spread with butter and fry in a large skillet until golden. Serve the creamy spread alongside.
