Prepare sweet and sour red chili sauce (if desired, recipe not provided).

Combine cilantro roots, garlic, and black pepper in a mortar.

Pound the ingredients into a fine paste.

In a small bowl, blend the paste with water to create a cilantro water mixture.

In a medium-sized bowl, combine rice flour, all-purpose flour, sugar, baking powder, and salt.

Stir in the whole kernel corn.

Blend in the cilantro water mixture until well combined.

Heat vegetable oil in a wok to 375 degrees Fahrenheit.

Test the oil by dropping a 1-inch bread cube; it should turn golden brown in 50 seconds.

Carefully drop spoonfuls (tablespoons) of the corn mixture into the hot oil.

Fry the fritters until golden brown on each side, turning as needed for even cooking.

Remove the fritters from the oil and drain on paper towels to remove excess oil.

Keep the fried fritters warm until ready to serve.
