Sour gummy candies are simple to grab from the store, but they're also easy to make at home—and, you can customize to your taste by choosing your own flavors and shapes. This simple recipe is made with unflavored gelatin, flavored Jell-O, and Kool-Aid. It is the Kool-Aid that contributes the sourness; make sure you buy unsweetened, which will be mostly citric acid. Try to match complimentary Jell-O and Kool-Aid flavors and colors for the best taste and appearance.

You can use any shape of candy mold to make the gummies. If you do not have candy molds, you can simply make the sour gummy candies in a pan and then cut them into squares; or use cookie cutters to turn the candies into your desired shape. Another option is to make them in ice cube trays or any other silicone mold you may have around the house.


  • 1 cup water

  • 3 envelopes unflavored gelatin

  • 2 packages Jell-O, any flavor

  • 1/2 packet unsweetened Kool-Aid, any flavor

Steps to Make It

  6. Place the pan or molds in the refrigerator to set for approximately 20 minutes. If you used candy molds, simply pop the gummy candy out of the molds. The candy in the pan can be cut into squares or a variety of shapes using cookie cutters.

Recipe Variation

Roll the candies in sugar to add a sweet crunch and counter some of the sourness.

How to Store Sour Gummies

Homemade gummy candies lack the preservatives that store-bought sour gummy candies have, so they are best stored in the refrigerator in a zip-top bag or airtight container.


  • Most of the Kool-Aid packets are unsweetened and require adding sugar when making the drink, but there are canisters of Kool-Aid powder that contain sugar. Be sure to use an unsweetened version.
  • To make a sugar-free candy, substitute sugar-free Jell-O.
  • Candy molds can be found in most craft or baking stores, or online.
  • If your sour gummy candies are sticking together, you can sprinkle a bit of powdered sugar or cornstarch on them prior to storing to prevent too much sticking.

Not Suitable for Vegetarians

If you are serving your candies to guests, remember that gelatin contains animal by-products and should not be consumed by vegetarians. For a ​vegetarian-friendly alternative, use agar powder in place of the gelatin. Agar powder is a natural thickener made from plants that are safe for vegetarians to consume.
