What You Need to Know
This technique involves slowly adding hot milk to a mixture of butter and flour while whisking, creating a stable emulsion through the formation of a complex network of starch and fat droplets. The key variable is the temperature of the mixture, which should be around 80°C. The pH range should be between 6.0 and 7.0.
This technique is unique in that it uses a combination of butter, flour, and milk to create a rich and creamy sauce, commonly used in Apulian dishes such as lasagna alla bolognese.
