How to make organic candy
Heat the oven to 200 degrees fahrenheit (93 degrees celsius).
Line a baking sheet with an oven-safe silicone baking mat. Place the baking sheet in the oven and allow it to warm up.

Pick from:
(1). Keep in mind that waiting too long will result in a soggy, burned-on candy. It is not mandatory that you wait too long to make homemade candies (processed versions of candy are available for purchase).;
(2). Then, add some skittles to the top of the baking sheet. Sprinkle some salt and black pepper to taste.;
(3). Mix and heat the sugar, vinegar, and cranberry juice. Combine the three ingredients in a 2-qt (2-liter).;
(4). The silicone coating should spread throughout the baking sheet and harden on one side. You can also store the silicone-free treats in an airtight container in the freezer if you plan to bake them soon.;
The answer is:
(3).
