Isaw- is the small intestines of a chicken.
No, it's not a worm. It's the first 4.5 feet of the chicken's bowels that is highly popular and sought for in the barbecue scene all over the Philippines. However gruesome this might be to you. Barbecue stands often run out of this long chewy but savory piece of chicken innards call Isaw. The small intestines is the first level of absorption of grounded food from the stomach of the chicken. It is where corn, rice, pellet feed are all mixed up and is ready to be absorved into the chicken's body. When vendors prepare Isaw. They do not remove grounded food in the intestine. They clean the intestines externally really well, but they won't drain the inside of it. Growing up. I have eaten this delicacy and still continue to do so whenever I have the chance. Back then, it was just starting to be a fad and it was always available in any barbecue stand we had in town. Now a days, its gotten very popular that sometimes. It's no longer available in the mix. If you're going to try Isaw. Make sure that it's fresh and properly marinated with the local barbecue sauce and the most important thing is that make sure that its cooked thoroughly. Order it with rice and the dipping sauce with vinegar, soy sauce, red pepper and calamansi and its nirvana. It's actually really good if you're into that kind of stuff. But if you're just a curious eater. I think you will like it as long as you stop thinking about what it is.
