I have already posted on salted egg making before. Friends were
curious on the use of mud. We have lots of anthill at home so its no
problem for us. Here's a more detailed process.
Gather anthill soil and soak in water until soften, about 5 hours.
Overnight soaking is preferred. Mashed the soil until smooth.
Strain using a fine net. Leave the "mashed" soil for about an hour.
Mud will settle at the bottom. Remove water on top.
Measure 1 part salt and 3 parts of the mud. Mix well.
Dip each duck egg in the mixture. Make sure the eggs are well coated
Arrange coated eggs in a box lined with old newspapers. Cover
and leave for 18 days. Wash eggs and boil until egg yolk is hard.
While still hot, dip the eggs in a pot of boiling food color.
Dad uses food coloring called Grana. A cup of Grana can color about
5,000 to 6,000 eggs.
