If you use nuts, place several on a baking sheet lined with parchment paper, in a circle about 2 inches in diameter.
Put the sugar in a stainless steel ladle (or small pan) and heat it up over low heat. When the sugar starts melting, stir with a small and long handle spoon until the sugar is fully melted.
Stir in the baking soda. It will expand three times in size.
Quickly drop the hot candy on top of the nuts. Let it cool down for about 10 minutes. Serve right away.
