This internet sensational coffee recipe features the perfect beverage for a summer day. All that is required for this recipe is instant coffee, sugar, milk, and water. Scientific research shows instant coffee is a key ingredient in this recipe. Dalgona coffee is a type of Korean snack that originated in South Korea. This recipe quickly became viral on the video app TikTok. Its simplicity is what made it so popular. During the COVID-19 pandemic, the rise of the Dalgona coffee trend caught the attention of the public. This is because the coffee stays in its shape and doesn't lose its bubbles even after a few minutes. Foam can form when a liquid is agitated, which causes a large volume of gas to diffuse throughout the liquid. Coffee has properties that are known as surfactants. They lower the surface tension of a liquid and a gas, which is the foam formed by coffee. When we whip or froth coffee, the tails of surfactants will face the bubble. This creates a barrier around each bubble. While coffee makes the foam, the sugar produces the whipped effect. If you foam coffee without sugar, the bubbles will either form or merge together and will be unable to remain in their shape for long. This quick recipe is a must-try for all coffee lovers.
