Korean Dalgona Milk (Caramel Puffed Sugar Candy Milk)
Dalgona, the Korean honeycomb candy made by puffing melted sugar with baking soda, gets crushed and dissolved into cold milk for a caramel-flavored drink. The baking soda needs only a few seconds of fast stirring; keep going and the bubbles collapse, leaving the candy dense instead of light and brittle.
