3. Wash and Dry Grapes Thoroughly
Wash the grapes under cold running water and remove them from the stems. This is crucial: the grapes must be completely, absolutely dry before dipping. Any moisture will prevent the candy coating from adhering properly and will cause the coating to slip off. After washing, pat the grapes dry with paper towels, then let them air dry on a clean kitchen towel for at least 30 minutes. Some people even use a hair dryer on the cool setting to ensure they’re bone dry.
4. Insert Toothpicks
Once the grapes are completely dry, insert a toothpick or small wooden skewer into the stem end of each grape. Push it in far enough to be secure but not so far that it goes all the way through. The toothpick serves as a handle for dipping and allows the grapes to dry without touching a surface. Prepare all your grapes this way before starting the candy coating.
5. Prepare Your Drying Station
Line a large baking sheet or two with parchment paper or a silicone baking mat. Have a styrofoam block, an upside-down colander, or another surface with holes where you can stick the toothpicks to hold the grapes upright while they dry. You need a way to suspend the grapes so the candy coating hardens evenly on all sides without touching anything.
6. Make the Candy Coating
In a medium, heavy-bottomed saucepan, combine the sugar, water, corn syrup, and cream of tartar. Stir gently over medium heat until the sugar dissolves completely. Once dissolved, stop stirring. Clip a candy thermometer to the side of the pan, making sure the bulb doesn’t touch the bottom.
7. Boil the Candy Mixture
Bring the mixture to a boil without stirring. Let it boil until it reaches 300 to 310 degrees Fahrenheit on the candy thermometer. This is called the hard crack stage and is essential for creating a hard candy shell. This takes about 15 to 20 minutes. Watch carefully toward the end as the temperature rises quickly. Don’t let it exceed 310 degrees or the candy will burn and taste bitter.
8. Remove From Heat
Once the candy reaches 300 to 310 degrees, immediately remove the pan from the heat. The mixture will be extremely hot and will continue cooking from residual heat, so timing is important. Let it sit for about 1 minute to stop bubbling, but work quickly before it starts to harden.
9. Divide and Color
If making galaxy grapes with multiple colors, carefully pour the hot candy mixture into 2 to 3 small, heatproof bowls, dividing it as evenly as possible. Add 2 to 3 drops of different gel food coloring to each bowl – purple in one, blue in another, pink in the third. Add the flavoring extract if using. Stir each bowl gently but quickly to incorporate the color. Gel food coloring works much better than liquid, which can cause the candy to seize.
10. Work Quickly
Candy coating begins to harden as it cools, so you need to work relatively quickly once you’ve colored it. If the candy becomes too thick to dip before you finish all the grapes, you can very carefully reheat it over low heat for just a few seconds, stirring gently, until it becomes fluid again. Be careful not to overheat.
11. Dip the First Grapes
Holding a grape by the toothpick, carefully dip it into one color of the candy coating, swirling it gently to coat completely. Lift it out and let excess candy drip back into the bowl. The coating should be thin and even. Immediately stick the toothpick into your drying station so the grape is suspended and not touching anything. Work quickly to dip several grapes in the first color.
12. Create Galaxy Effect
For the galaxy effect, you can dip grapes in one color, let them dry for just 30 seconds, then drizzle or dip one side in a second color. Or dip the grape halfway in one color, then dip the other half in a different color. You can also use a toothpick to drizzle different colored candy over already-coated grapes. The key is working before the candy hardens completely so the colors blend slightly at the edges, creating that cosmic, swirled appearance.
13. Add Glitter Immediately
While the candy coating is still wet and tacky, sprinkle edible glitter or luster dust over the grapes. Use a small spoon or your fingers to dust them generously. The glitter should stick to the wet candy. Use different colors of glitter to enhance the galaxy effect – purple, blue, pink, and silver all work beautifully. Don’t be shy with the glitter – more is more for that dramatic sparkle effect.
14. Let Dry Completely
Once all grapes are dipped, colored, and glittered, let them dry completely at room temperature. This takes about 30 minutes to 1 hour. The candy coating should be completely hard and no longer tacky to the touch. Don’t try to remove the toothpicks or move the grapes until they’re fully set or you’ll damage the coating.
15. Remove Toothpicks
Once completely dry and hard, carefully twist and pull the toothpicks out of the grapes. They should come out fairly easily, leaving a small hole where the toothpick was. If a toothpick is stuck, gently wiggle it while pulling. The hole will be small and barely noticeable.
16. Arrange and Serve
Arrange the galaxy candy grapes on a serving platter or in a bowl. They look stunning when grouped together, with their different colors and sparkles creating that cosmic, galaxy appearance. The combination of purple, blue, and pink with the shimmer from the glitter truly does look like a nebula or galaxy.
17. Storage
Store galaxy candy grapes in an airtight container at room temperature, separated by layers of parchment paper to prevent sticking. They keep for up to 3 days, though they’re best eaten within 24 hours for the crunchiest coating and juiciest grapes. Don’t refrigerate as humidity will make the candy coating sticky and soft.
18. Tips for Success
The grapes MUST be completely dry before dipping. This cannot be emphasized enough. Even the slightest moisture will cause the candy coating to slide right off or become sticky and never harden properly. A candy thermometer is essential for this recipe. Guessing the temperature will result in coating that’s either too soft or burnt and bitter. Invest in a reliable candy thermometer. Don’t stir the candy mixture once the sugar has dissolved. Stirring causes crystallization which makes the candy grainy and opaque instead of smooth and clear. Gel food coloring is far superior to liquid food coloring for candy making. Liquid introduces moisture that can cause the candy to seize or become grainy. Work in a dry environment. High humidity makes candy coating difficult as the sugar absorbs moisture from the air. Choose a dry day if possible. The hard crack stage (300-310°F) is crucial. Below this temperature, the coating will be too soft and sticky. Above it, the candy will burn. If the candy hardens too quickly while dipping, carefully reheat it over very low heat just until it becomes fluid again. Don’t overheat or you’ll burn it. For the best galaxy effect, use at least three colors and layer them or swirl them together on the grapes. The more colors, the more cosmic the appearance. Edible glitter is available at craft stores, baking supply stores, or online. Make sure it’s labeled as edible, not just decorative. Some glitters are for decoration only and not safe to eat. For an even more dramatic effect, use different colors of glitter on different colored sections of the grapes to create more contrast and shimmer. These grapes are essentially candy-coated fruit, so while they contain fruit, they’re definitely a treat rather than a health food due to the sugar coating. However, they do provide the nutrients from the grapes inside. Kids love making these because they’re fun, colorful, and the science of candy-making is fascinating to watch. Supervise carefully around the hot candy mixture. Different grape varieties work equally well. Red grapes create a slightly different color effect than green grapes under the coating, but both are delicious. For themed parties, you can customize the colors. Use reds and greens for Christmas, pastels for Easter, orange and black for Halloween, or school colors for graduations. The galaxy theme works for space-themed parties, science parties, or anywhere you want something visually stunning. These make excellent party favors when individually wrapped in small cellophane bags tied with ribbons. The coating protects the grape and makes them easy to package. If you’ve never made candy before, this recipe is a good introduction to candy-making techniques. The process teaches you about sugar temperatures and working with hot sugar. Making these is easier than it seems once you understand the key principles: dry grapes, proper temperature, and working quickly. Practice makes perfect – your first batch might not be perfect but you’ll improve quickly.
