1974. Cunanan's trademark sisig was developed in mid-1974 when she served a concoction of grilled and chopped pig ears and cheeks seasoned with vinegar, calamansi juice, chopped onions and chicken liver and served in hot plates. Today, varieties include sisig ala pizzailo, pork combination, green mussels or tahong, mixed seafood, ostrich sisig, crocodile sisig, spicy python, frog sisig and tokwa't baboy, among others. Preparation According to Cunanan's recipe, preparing sisig comes in three phases: boiling, broiling and finally grilling. A pig's head is first boiled to remove hairs and to tenderize it. Portions of it are then chopped and grilled or broiled. Finally, coarsely chopped onions are added and served on a sizzling plate. Variations of sisig may include pork or chicken liver and/or any of the following: eggs, ox brains, chicharon (pork cracklings), and mayonnaise; although these additions are common nowadays, they are frowned upon by the traditionalist chefs of Pampanga as it deviates far from the identity of the original sisig. Recently, local chefs have experimented with ingredients other than pork such as chicken, squid, tuna, and tofu. Festival The annual "Sisig Festival" (Sadsaran Qng Angeles) is held every year during December in Angeles, Pampanga, celebrating the Kapampangan dish. It started in 2003 and was made an annual festival by Mayor Carmelo Lazatin in December 2004 to promote the city's culinary prowess. The festival also features a contest where chefs compete in making dishes, primarily sisig. Congo Grille, a restaurant chain in the country, was the winner in 2006. In 2008, the festival was put on hiatus following Aling Lucing's death. In 2014, Ayala Malls's Marquee Mall incorporated the festival by including it within their annual Big Bite! Northern Food Festival, held every October or November. The Angeles City Tourism Office organized a festival on April 29, 2017. The revival of the festival was in line with the Philippine Department of Tourism's Flavors of the Philippines campaign. Now called "Sisig Fiesta", the festivities were held at Valdes Street, Angeles (also known as "Crossing" since it was a former railroad track), where Aling Lucing reinvented the dish. The newly revived Sisig Fiesta was a one-day event that featured a line up of sisig sampler banquet, sisig and BBQ stalls, cooking demonstrations with celebrity chefs, and a showcase of Angeleño culinary talent through competitions.
