Panecillos de San Nicolas, also known as putu saniculas or simply saniculas to the Kapampangan, is one of the heirloom recipes learned by some of the older families in Pampanga from the Augustinian friars during the Spanish era. Actually, these panecillos or little pan, are not classified as bread, but rather as biscocho or biscuits. These biscuits have the characteristic image of San Nicolas de Tolentino, also called Apung Kulas, embossed on its flat round surface. San Nicolas is one of the important saints of the Augustinian religious Order and is the designated patron of one of the oldest established pueblos in the Philippines, the town of Macabebe in the province of Pampanga.
Sisig was one of the first Kapampangan words explained to Spanish missionaries by the Augustinian priest, Fray Alvaro de Benavente. He published it in his book, "Arte de Lengua Pampanga" in 1699. He referred to "sisig" as a manner of preparing food as in "guisar con vinagre, v.t. ensalada" or simply, to cook with vinegar, or make a salad.
