Deep-fried kwek kwek is a type of tokneneng, the omnipresent Filippino street food. While tokneneng is made with boiled chicken or duck eggs, kwek kwek is the smaller sized variety, which usually employs tiny quail eggs. Both types are distinguished by the deep orange color, provided by an unusual batter in which eggs are coated before frying.

The thick batter is made with flour, cornstarch, and water, with the addition of annatto powder, a unique ingredient which gives the dish its remarkable orange color. Hard-boiled quail eggs are thoroughly coated in batter, and fried until crispy.

The essential condiment to kwek kwek is a spicy and sour sauce. It is usually prepared with vinegar, soy sauce, brown sugar, chilis, and occasionally ketchup, and it is always served on the side as a dipping sauce. Kwek kwek eggs are sold by numerous street vendors, who sell them alongside other delicious deep-fried Filipino snacks, such as fish or squid balls.
