Place the sausages in the Remoska. Put the lid on and switch on. Cook until nicely browned on at least one side which will probably take 20-30 minutes.
Put the flour in a bowl, make a hole in the middle and add the egg, milk and salt. Using an electric whisk, mix together well, drawing in the flour gradually until a smooth batter.
Pour into the Remoska and cook for a further 35-45 minutes, by which time the batter will have risen beautifully and be nice and crispy around the edges.
