Preserved Lemons
Pickled in salt, water, and lemon juice (and sometimes with sweet nigella flower seeds); served in Morocco in meat tagines and with roast chicken.

Pig's Feet
This American soul-food classic is preserved in a vinegar brine and usually eaten as a snack.

Duck Eggs
Immersed in a saltwater brine for a week or more; often used for hard or soft boiling in China.

Preserved in a mixture of salt, oil, and spices, such as cayenne pepper and mustard seeds; in India, eaten as a snack or served with rice at meals.
