Sour Burst Grapes

Citric acid is found naturally in several fruits and berries, and is commonly added to many foods and beverages as a preservative or for flavor. It has a tart taste, and is also known as lemon salt or sour salt. When a recipe calls for "sour salt" it is referring to citric acid. It's a white granulated powder that is extracted from the juice of citrus and other acidic fruits (gooseberries, lemons, limes and pineapples). It can also be created by fermenting glucose with special citric acid producing bacteria. Citric acid is completely natural. It gets its name from the citrus fruit family, which includes lemons, limes, oranges, tangerines, and grapefruits. Citrus fruits owe their sharp and bitter taste to citric acid, especially the more sour ones like lemons and limes. Studies have shown that citric acid can help your bones absorb calcium more easily.

Our customers have used our citric acid as an ingredient in pretty much everything: cheeses, ice cream, alcoholic beverages, breads, and more. Because of its characteristic tart flavor, citric acid is often added to soft drinks and sour candies (the white, powdery coating on sour candies is likely citric acid). The strong, tart taste of citric acid is used as a flavoring agent to foods, beverages and even a couple of our salt-free blends.

Prep Time 15 minutes
Total Time 2 hours 15 minutes
Yields About 4 servings (1 pound of grapes)

Ingredients

  • 1 pound green seedless grapes
  • 6 tablespoons lemon juice

For the candy coating (makes three colors)

For an extra sour version

Directions

  1. Step one: Rinse the grapes, pull them from the stems, and pat them completely dry. Leftover rinse water is what turns the coating into wet clumps later. Line a baking sheet with parchment paper.
  2. Step two: Pour the lemon juice over the grapes and toss to coat, then let them sit for about 10 minutes. Every grape should be lightly wet so the coating has something to grab.
  3. Step three: Set out three shallow bowls. In each one, stir together 1/4 cup granulated sugar, 2 teaspoons citric acid, and 1 tablespoon of a different flavored gelatin powder. Taste a pinch of each and add more citric acid if you want a sharper bite.
  4. Step four: Divide the grapes into three batches. Lift each batch out of the lemon juice, let the excess drip off, and roll them in one of the coatings until fully coated. If a coating starts to look like wet sand, mix a fresh bowl using the same ratio. Damp sugar will not stick.
  5. Step five: Arrange the coated grapes in a single layer on the parchment-lined tray, keeping the colors in their own sections so they do not bleed into each other.
  6. Step six: Refrigerate for about 2 hours, until the coating sets into a crisp shell. Serve cold and enjoy!

Tips and Tricks

  • Serving young children? Cut the grapes in half lengthwise before coating. Whole grapes are a choking hazard for toddlers and young kids, and halved grapes pick up more coating anyway.
  • Let the kids dip their own. Set out the three bowls with toothpicks and let everyone build their own tray. It is the easiest party activity in this whole recipe file.
  • Freeze them instead. For a firmer, sorbet-like bite, freeze the coated grapes for 2 to 3 hours rather than refrigerating. Pull the toothpicks out first so they do not freeze to the fruit.
  • Dry grapes, dry sugar. The two most common problems are the same problem. Pat the grapes dry after rinsing, work in small batches, and start a fresh bowl the moment one turns damp.
  • Go sharper with malic acid. Malic acid is sharper and lingers longer than citric, which is brighter and hits first. Swapping in a teaspoon per bowl is how commercial sour candy gets that layered pucker.
  • Mix your own colors. Unsweetened drink mix works the same way as flavored gelatin and comes in more shades. Use about the same amount.
  • Serve them fresh. These are best the day they are made, while the shell is still crisp.

Prefer them without the dye?

Frozen Sour Grapes use the same lemon juice and citric acid with nothing else in the coating. Four ingredients, no artificial color, and a crackly frozen shell.
