Through early records, it is evident that taho traces its origin to the Chinesedouhua. The dish was introduced to the Philippines and other Southeast Asian countries by historical Chinese migration.
Processing and preparation
Most taho vendors prepare the separate ingredients before dawn. The main ingredient, fresh soft/silken tofu, is processed to a consistency that is very similar to a very fine custard. The brown sugar is caramelized and mixed with water to create a viscous amber-colored syrup called arnibal. Flavors, like vanilla are sometimes added to the arnibal. Sago pearls, purchased from the local market, are boiled to a gummy consistency until they are a translucent white. In lieu of making soft tofu from scratch, one can use a soft tofu mix from the store. Leftover taho, if significant amounts are found, are sometimes repurposed into Tokwa.
Marketing
The Magtataho is a common sight in the Philippine streets. A magtataho carries two large aluminum buckets that hang from each end of a carrying pole. The larger bucket carries the tofu base; the smaller bucket holds the arnibal and sago pearls. Taho vendors peddle their product in a distinctive manner, calling its name in a full, rising inflection as they walk at a leisurely pace on the sidewalk or along the side of the road. Most magtatahokeep a habitual route and schedule, often calling out "Tahoooooo!" to attract a customer's attention. Though vendors are most likely to ply their routes early in the morning, it is not uncommon for a magtataho to be spotted in the late afternoon or evening as well. Most magtataho carry plastic cups, often in two sizes, and spoons for their product. Some customers in residential areas tend to use their own cups, and the vendors price their product accordingly. Using a wide, shallow metal watch glass-shaped scoop, they skim the surface of the bean curd and toss out any excess water, before scooping the bean curd itself into a cup. Then, using a long, thin metal ladle, they scoop sago or tapioca pearls and arnibal into the cup, loosely mixing it in.
Eating
Taho is enjoyed either with a spoon, sipping it with a straw, or by simply slurping it straight from the cup. Though traditionally served warm, cold varieties exist in supermarkets and food stalls in cafeterias with bean curd in a solid, unbroken state. These pre-packed cups, sold with a plastic spoon or wooden ice pop stick, tend to contain a firmer tofu.
