"Merienda" means snack time in this country. Similar to a British tea-time, there is a morning and an afternoon merienda.
Donuts are one popular merienda treat, and Dunkin' Donuts rate pretty high. Their slogan, "Pasalubong ng Bayan," is something to the effect of "A great souvenir gift!"
So after a trip to the city, donuts are a great gift to bring back to the folks at home.
Along with the standard chocolate frosted, there are a few less familiar types. The purple one is an Ube donut. Ube is a bright purple yam used often in desserts like ice cream and cake.
Would you be surprised to learn that the Filipino donuts are just about 1/2 the size of their American counterparts? I wonder if it's just another commentary on American consumption?
