The Philippines has been colonised by the Spanish for more than 300 years. The word ensaladang is obviously a Filipino corruption of the Spanish word ensalada meaning salad, and talong is the Filipino word for… you guessed it: eggplant (FYI the Spanish for eggplant is berenjena).
There are many versions of sumans out there, it depends on what region it comes from. The best suman I have had is called Moron (yes, that's spelled correctly) from Samar Island. The most common suman is what you find in all markets across the country is arguably, a Filipino's comfort food. Shaped like a brick, brown and sweet, it's a convenient healthy snack as its made of rice, coconut milk and sugar.
