Kumquat-Riesling Gummies

Bright orange kumquats give these gorgeous gummies their all-natural sunny glow and a puckery, sweet-and-sour flavor. To play up the tartness, a citric acid coating adds a burst of sour flavor and a craveable quality. Kung Fu Girl Riesling has notes of white peach, mandarin orange, and apricot that balance the tang. Want to gift these? The sugar-citric acid coating helps keep these gummies from sticking together when packaged in cellophane bags; pop in a silica gel packet to absorb moisture and keep your candy structurally sound and looking beautiful.

Total Time:
1 day 1 hrs
10 dozen candies


  • 4 ounces fresh kumquats (about 3/4 cup), quartered lengthwise and seeded

  • 2/3 cup cold water, divided

  • 3/4 cup (6 ounces) dry Riesling

  • 1 cup granulated sugar, divided

  • 1/3 cup light corn syrup

  • 1/4 teaspoon fine sea salt

  • 1 teaspoon citric acid, divided

  • 3 (1/4-ounce) package unflavored gelatin

  • Grapeseed oil, as needed


  1. Place kumquats and enough water to cover by 1/2 inch in a small saucepan. Bring to a boil over medium-high. Remove from heat; drain. Repeat blanching process; drain well. Process drained kumquats and 1/3 cup cold water in a blender until smooth, about 30 seconds. Using the back of a spoon, press mixture through a fine wire-mesh strainer into a bowl; discard solids. Set puree aside.

  2. Combine Riesling, 3/4 cup sugar, corn syrup, salt, and 1/4 teaspoon citric acid in a small saucepan. Cook over medium, swirling pan occasionally, until a candy thermometer registers 260°F (hard-ball stage), 15 to 25 minutes. Stir in kumquat puree (temperature will drop). Cook, stirring constantly, until thermometer registers 240°F, 5 to 10 minutes. Remove from heat, and let cool, stirring occasionally, until temperature reaches 200°F, about 5 minutes.

  3. Meanwhile, stir together gelatin and remaining 1/3 cup cold water in a small bowl. Set aside to bloom, about 5 minutes.

  4. Remove candy thermometer, and gently stir gelatin mixture into warm syrup until gelatin is dissolved and mixture is smooth. Let stand at room temperature 5 minutes. Skim off any foam that forms on surface. Place a 140-cavity half-sphere or semi-sphere (about 3/4-inch cavity) silicone candy mold on a large rimmed baking sheet. Carefully spoon 1/4 to 1/2 teaspoon mixture into each cavity. Alternatively, pour mixture into a 9- x 5-inch loaf pan. Chill mold on baking sheet, uncovered, until candies are set, at least 4 hours or up to overnight.

  5. Remove gummies from mold, and place on a wire rack. (If using a 9- x 5-inch loaf pan, use a sharp knife to cut gummies into uniform squares.) Let stand at room temperature in a cool, dark place, uncovered, until gummies are no longer sticky and have dehydrated to desired degree of chewiness, 1 to 3 days. If gummies reach desired chewiness but are still slightly sticky, toss batches of 6 gummies with a few drops of grapeseed oil to coat. Store in an airtight container up to 2 weeks.

  6. Just before serving, stir together remaining 1/4 cup sugar and remaining 3/4 teaspoon citric acid in a small bowl. Dip bottom of each gummy in sugar mixture. Sugared gummies can be held at room temperature up to 4 hours.

Make Ahead
