Dalgona is a traditional and nostalgic candy originating from South Korea. It has recently been popularized by the Netflix hit show called Squid Game. The dalgona is made by melting sugar and mixing it with baking soda. The mixture should start to foam up and look similar to whipped coffee.

It is poured out onto a flat surface and flattened into a thin disk that's imprinted with a mold before it hardens and the texture becomes brittle. When enjoying dalgona, the trick is to eat around the pattern so that it doesn't break, and some street food vendors will give another dalgona to children if they successfully break off the exterior part of the candy while saving the shape.
