Lesson 1Brine salting vs dry salting: concentrations, times, and salt uptake considerationsThis lesson compares brine and dry salting for semi-hard cheeses. It covers brine strength, temperature, time, application rates, salt uptake, rind formation, and effects on flavour, texture, and safety in Uganda.
