Ingredients

Green grapes. I bought the largest, roundest fresh green grapes I could find. Look for firm, fresh, and seedless grapes for the best results.

Lime juice. Lime juice not only adds to the tang for the essential “sour patch” flavor, but it also helps the monk fruit coating to stick to the grapes.

Monk fruit sweetener. I’ve been using granulated monk fruit sweetener more and more in my recipes for a subtle, clean sweetness that’s low-glycemic. Monk fruit sweetener is a natural, zero-calorie sweetener derived from the juice of monk fruit, a small melon native to Southeast Asia. It’s often used as a healthier alternative to sugar, as it does not raise blood sugar levels. I look for monk fruit sweetener that doesn’t have erythritol.

Ascorbic acid (Vitamin C powder). You could omit the vitamin C powder (ascorbic acid), however if you want to dial up the tangy sour factor, I suggest adding it. You’ll also be adding more vitamin C to this recipe too.

Pink pitaya powder. Pink pitaya powder is used for a the pink color. You will need 1/2-1 teaspoon.

Blue spirulina powder. Blue spirulina powder is used for a dreamy blue. You will need 1/2 teaspoon.

Beet powder. Red beet powder is used for the earthy red. You will need 1/2-1 teaspoon.

Matcha powder. Matcha powder is used to enhance the natural green. You will need 1/2-1 teaspoon.

How to Make Naturally Colored Sour Patch Grapes

1. Prep the Grapes

Wash your grapes thoroughly, removing the stems, and then pat them completely dry (this helps the coating stick!).

2. Mix the Coating

In a small bowl, combine 1/4 cup of the monk fruit sweetener, 1/2 teaspoon of ascorbic acid, and one of the superfood powders. Adjust the ratio to your preferred sourness (add 1 teaspoon of ascorbic acid if you prefer a more sour taste).

3. Coat

Squeeze the lime juice over the grapes and gently toss to coat each grape with the lime juice.

4. Roll

Line a baking sheet (that will fit into your freezer) with parchment paper. Working with a few grapes at a time, roll 1 cup of the grapes in the first colored coating, covering each grape completely. Place the coated grapes on a parchment-lined baking sheet, spaced far enough apart as to where they’re not touching each other. Once you’re done with that color, repeat the process using another color. Combine another 1/4 cup of the monk fruit sweetener with another 1/2 teaspoon of ascorbic acid and a different colored powder this time. Roll the second cup of grapes in this color. Repeat for the remaining 2 colors.

5. Freeze

Once all grapes are coated, freeze them for 2-3 hours to set the coating. Serve cold for the best sour candy experience! Keep them stored in an airtight container in the freezer.

Tips for Success

Dry the grapes completely after washing.

I know it may seem silly since we’re rolling the grapes in lime juice, but making sure the grapes are completely dry after washing them with water makes a big difference! If they are still wet with water, the monk fruit coating won’t stick to the grapes.

Roll the grapes in one color at a time.

I found the most success in being able to coat the grapes if I worked with 1 colored monk fruit mixture at a time. The pink pitaya and blue spirulina when mixed with the monk fruit ascorbic acid mixture turned almost into a sand-like texture if it sits too long, and then it doesn’t stick to the grapes 🤔. So only mix together the colored monk fruit mixture when you’re ready to use it.

Don’t roll more than a few grapes at a time.

If you add too many grapes into the bowl it makes the sweetener too wet and it won’t stick to the grapes. I like to roll 1-3 grapes at a time.

Keep the grapes separated on the baking sheet.

Be sure to keep the colors separated into same-color groups on the baking sheet so that they don’t rub off on one another. Not a huge deal if they do, but just something to note if you’re a bit of a perfectionist like me 🤭.

💡 Troubleshooting
If you are having issues with the monk fruit coating sticking to the grapes, make another batch of colored monk fruit coating making sure the bowl is completely dry. Make sure the grapes have been completely dried after washing, and make sure they are coated well in lime juice before rolling. Work quickly and with 1 grape at a time and work with dry hands.

FAQs

Can I use red or black grapes?

Absolutely! The coating works on any variety, but green grapes provide the classic “Sour Patch” vibe and best contrast for the colors.

Is ascorbic acid necessary?

For authentic sour candy flavor, yes! This pure Vitamin C powder adds tartness, but you can omit if you choose.

Can I use regular sugar?

You may use organic cane sugar, but keep in mind it may alter the color and it’s not an unrefined sweetener like monk fruit.

Do I have to use the color powders?

Nope! You can still make this recipe without the colors, although a lot less fun! 😜 Simply combine the total amount of monkfruit sweetener (1 cup) and 2-4 teaspoons of ascorbic acid in one bowl and then roll the grapes.

Do the colored powders add a flavor to the grapes?

In my opinion, the pink pitaya powder and the spirulina powder are flavorless. You may pick up on just a hint of the matcha powder and beet powder, but it’s very faint. If you don’t like it, use less powder, but keep in mind the color will also lessen.
