The Filipino street-food snack made from grilled, skewered chicken intestines is isaw.
Isaw is prepared by thoroughly cleaning chicken intestines, boiling them, placing them on bamboo skewers, and grilling them over charcoal. Vendors commonly brush the skewers with a sweet or savory marinade. Diners often dip them in vinegar-based sauces, which add acidity to the smoky flavor.
The snack became strongly associated with Filipino street-food culture and is especially popular near schools, markets, and busy urban areas. Pork intestines may also be sold as a related version, sometimes called pork isaw, while chicken isaw is the most familiar form.
Isaw is not the same as balut, which is a developing duck embryo boiled and eaten from its shell. It is also distinct from kwek-kwek, quail eggs coated in orange batter and deep-fried. These foods are commonly sold by the same vendors but are separate snacks.
