Filipinos like their food sweet. A prime example of this is the
spaghetti sold in fast food stores, which is really sweet, and even
has a hot dog in it.
It came as no surprise, then, when someone decided to make
ketchup from bananas.
Banana ketchup is sweeter than the typical tomato variety and is
a popular condiment found in any typical Filipino household. The
taste is similar to Thai chili sauce.

Banana is mixed with sugar, vinegar, spices and, finally, food
coloring, to make it look like tomato ketchup.
Banana ketchup was ubiquitously sold during World War II, when
there was a shortage of tomatoes. Since then, Filipinos have not
lost their love for this sweet condiment, using it to flavor their
French fries, fried chicken, hotdogs and omelets.
