Kwek-Kwek is a quail egg that’s been hard-boiled then dipped in an orange batter. The batter is composed of baking powder, flour, food coloring, and salt.
1/2 cup vinegar,
(1/4 cup water -optional), 1 small red onion-chopped finely, 1 teaspoon salt, 1/4 teaspoon ground pepper, (1 hot chili, chopped-optional)
I used liquid food color, combining red and yellow to get the hue I like. Food color in powder form is also ok to use.
You may also use annatto powder to color the batter.
