Make candy from scratch! It's as simple as stirring, boiling and reading a thermometer. Really!
Prepare you pan or molds: Oil a piece of foil and line an 8x8-inch pan. Silicone molds are non-stick, but if the design is intricate you may want to lightly oil it.
Combine the sugar, corn syrup, and water in a medium saucepan. Stir until clear, then not again. Bring to a boil without further stirring.
Clip a candy thermometer to the edge of the pan, taking care the bulb doesn't touch the bottom of the pan. Continue to boil without stirring, until the mixture reaches 300°F/150°C (hard crack stage).
Take the pan off heat immediately and remove the thermometer. Add the food coloring and flavor oils and stir just until combined. It will bubble a little.
When the bubbling stops, pour the sugar syrup into the prepared candy mold or lined pan.
If using a foil-lined pan, score the candy into 1/2-inch squares using a butterknife. If the lines don't hold shape, wait 2 minutes then try again.
Let the candy harden and fully cool (about 20 minutes). Push the individual pieces out of the silicone mold or lift the foil out of the pan and snap it at the scored lines to make individual pieces of hard candy.
