In English---salted red eggs!!! The eggs have an intense flavor, salty taste and a grainy yolk and are often eaten with mangoes or tomatoes and vinegar. . This is a local favorite and can be found on sale at most markets.
The duck's eggs are made salty by soaking them in brine and are then painted red to distinguish them from normal eggs!! TRY ONE, THEY ARE DELICIOUS!!!
Local people usually do not use the same vinegar as we use in the West but they produce their own from the sap of the coconut tree. The liquid is collected and strained through a cloth before adding sugar. The mixture is then pasteurized for 20 minutes at 65 degrees celcius before being poured into containers (usually plastic coke bottles). Then it is left to ferment for a week or so. You can actually drink the liquid before it ferments and it is quite delicious but once it starts fermenting you can get a little drunk on it. You will see it on sale at most markets for around 40 pesos for 1.5 liters.
