Kwek kwek is a Filipino snack made of quail eggs coated in an orange batter and deep fried. It is commonly eaten with vinegar. To start a kwek kwek business, one needs budgets for raw materials, space rental, salaries, as well as equipment like a food cart and stove. The process involves boiling and shelling eggs, making the batter, coating and deep frying the eggs, and serving on sticks with dipping sauces. Selling kwek kwek in public places attracts customers and can be a profitable business.
