In a metal ladle or small saucepan, heat the sugar over low heat until it melts into a golden syrup. Stir constantly with a wooden chopstick or skewer to avoid burning.
Once fully melted, remove from heat and quickly stir in the baking soda. The mixture will foam and lighten in color.
Pour onto parchment or a silicone mat and press flat with a greased metal plate or smooth object.
Optional: Press a cookie cutter into the center to make a shape.
Let cool and harden for 1–2 minutes before enjoying—or attempting the extraction challenge.
