Cook. Pour the syrup into a deep sauce pan and boil it over medium-high heat to 235°F (113°C) (soft-ball stage). When cooking sugar for candy making you really need an accurate digital thermometer. The syrup will foam madly, so make sure your pan is not more than half full and keep a close eye on the pan so it doesn't boil over.
Collect your snow into a shallow 1 1/2 quart (1.5L) baking dish or small sheet pan. Pack the snow down tightly. To keep it from melting, store the packed snow in the freezer.
When the syrup reaches 235°F (113°C), immediately use a ladle or deep spoon to drizzle the hot syrup onto the snow in strips. Let it cool for a minute. The syrup will begin to firm up as it cools.
Serve. You can then roll up the taffy with a popsicle stick or a fork and serve immediately. Don't leave it on the snow too long or the snow will melt and dissolve the taffy.
