Make the candy syrup

• Add the sugar, corn syrup and water to a pot, scraping all the corn syrup out of the measuring cup.
• Stir in the white and pink food coloring so the syrup is opaque rather than transparent.

Heat to 300 °F

• Insert a candy thermometer and heat without stirring at all.
• Let the syrup reach 300 °F, then remove the pot from the heat.

Prepare the coating

• Combine the Nerds and crushed Jolly Ranchers in a bowl.
• Line a tray with parchment paper.

Dip and coat the grapes

• Holding each grape by its toothpick, dip it into the hot syrup.
• Roll the grape in the Nerds and Jolly Rancher mix until fully coated.
• Place the coated grapes on the lined tray to set.
