If you’ve ever tried the viral Fruit Riot Sour Grapes 🍇, you know why recreating them at home was an absolute must. The concept is pretty simple, but the elite flavor and texture combo makes them wildly addicting! I’m talking, eat-the-whole-bag-in-one-sitting type of addicting 😩. But fear not. If these irresistibly overpriced tangy little gems also have a hold on you, I am here to release those shackles ⛓️💥 with my Frozen Sour Grapes DIY version. They are so simple to make, and the customization options are endless. The best part? They only take 5 minutes to prep, and after that, it’s just a matter of waiting for them to freeze into little sour bites of perfection.
Why You’ll Love DIY Frozen Sour Grapes
Warning: This recipe may cause a serious grape addiction! I’m not kidding, the first time I made these, I finished the whole batch and made another one within the same day 😅. When you bite into these Frozen Sour Grapes you get that icy 🧊, crunchy pop, immediately followed by a sour tang from the citric acid and lime that makes your mouth pucker in the best way possible. The Tajin adds a spicy and slightly salty kick, while the hot honey 🍯🌶️brings the sweet heat that takes these Frozen Sour Grapes to new heights. It’s like your favorite sour gummy, but refreshing, juicy and way more satisfying.
Ingredients
🍇 Grapes: For grape choice, any seedless variety works great, but green grapes tend to be the sourest and crunchiest when frozen. Red or black grapes will still be delicious, just slightly sweeter. I’ve tried this recipe with red and green grapes, and both work wonderfully!
🍋🟩 Lime: Lime adds that bright, zesty punch, but more importantly, the lime juice is what helps the citric acid and Tajin stick to the grapes, so don’t sleep on this key ingredient!
🧬 Citric Acid: Don’t let the acid part scare you off. Citric acid is a weak organic acid that occurs naturally in citrus fruits like lemons and limes. It’s what puts the “sour” in our Frozen Sour Grapes.
🌶️ Tajin: A popular Mexican seasoning blend known for it’s chili, lime and salt combo, Tajin is the perfect match for the lime and citric acid in this recipe. Of course, if you’re not a fan of Tajin, feel free to leave it out.
🍯 Hot Honey: My ultimate condiment and the perfect final touch to make these already delicious Frozen Sour Grapes the snack of your dreams.
Nonna’s Tip 🍇
Dry your grapes really well so the sour coating sticks. For extra tang, let them sit in the mixture for 10–15 minutes before freezing.
DIY Frozen Sour Grapes Tips for Success
- Taste as you go: Once you coat all your grapes, try one of them before you commit to freezing the entire batch. This way you ensure the level of sourness is on point.
- Let the 🍇 marinade: This is completely optional, but letting the grapes marinade in the lime, citric acid and Tajin mixture for 10-15 minutes ensures a deeper, more intense flavor.
- Dry the grapes well: Pat them all the way dry so the coating mixture sticks well and doesn’t slide off.
- Freeze Long Enough: I know you’ll probably be impatient the very first time, but trust me, they are worth the wait. Freeze ❄️ the Sour Grapes for at least 2-3 hours to get that crisp, candy-like snap.
- Use a baking sheet: Spread the coated grapes on a baking sheet to prevent them from sticking to each other when they freeze. Later on you can transfer them to a zip-lock bag and store them in the freezer.
Frozen Sour Grapes Variations and Substitutions
- Choose any seedless grapes you enjoy! Green grapes tend to be the best fit for this recipe since they are crunchy and slightly sour by nature, but red and black grapes 🍇work well too!
- Not a grape fan? Try this recipe with pineapple chunks 🍍, watermelon cubes 🍉 or pieces of mango 🥭, strawberry 🍓 or kiwi 🥝.
- If you want your grapes less sour, simply add less citric acid. You can also add a sprinkle of coconut sugar before freezing.
- Instead of lime, feel free to use lemon juice, orange juice, grapefruit juice or pineapple juice. You can use any juice as a base, but it may change the flavor and make the grapes less sour.
- Add some more texture by adding shredded coconut 🥥 or crushed, freeze-dried fruit powder to the mix.
- Drizzle these Frozen Sour Grapes with Chamoy instead of hot honey for a less spicy but more tangy twist!
- No citric acid? No problem! Use extra lime juice 🍋🟩 and a bit of lime zest for a milder, more natural tang.

Citric acid is the naturally sour compound found in citrus fruits. You can find it in the spice or canning section of most grocery stores, or online. It gives that classic “sour candy” zing.
You can, but the grapes won’t be as sour. If you’re looking for that tangy punch, citric acid is key.
Freeze them for at least 2–3 hours, or until completely solid. You can also leave them overnight.
Yes! Just store the frozen grapes in a sealed container or zip-top bag in the freezer, then drizzle the hot honey right before serving.
