Using dry ice to carbonate fruit. The fruit will be filled with tingly carbon dioxide bubbles, like a soda. The fizzy fruit is great to eat on its own or it can be used in recipes.
Fizzy Fruit Materials
- dry ice
- plastic bowl
Carbonate the Fruit
- You want the dry ice to be in small chunks. If your dry ice came as pellets or chips, you're in good shape. Otherwise you will need to smash your dry ice. Do this by placing the dry ice in a paper bag or by covering it with a dishcloth and smash it (gently) with a hammer. You want to break it into pieces, don't crush it.
- Dry ice vigorously sublimes into carbon dioxide gas. As this happens, the gas is pushed into the fruit. Thinner slices or pieces of fruit will become more saturated with carbon dioxide bubbles than larger pieces of fruit. You can use whole grapes or strawberries, but be sure to slice or chunk larger fruits, such as apples or bananas.
- Place some dry ice pellets in a bowl. Set the fruit on the dry ice. You can add more dry ice if you wish.
- Allow time for the dry ice to sublime (at least 10 minutes). The fruit will freeze and become carbonated.
- Eat the fizzy fruit, using it in recipes or add it to drinks (also makes interesting ice cubes). The fruit will remain fizzy as it thaws, but it should be used within an hour or so because it will lose its bubbles.
Fizzy Fruit Safety Tips
- There are videos that show people carbonating fruit by sealing dry ice and fruit in a plastic bottle. This is not a safe plan, since overpressuring the bottle will cause it to explode. If you decide to try this method, make sure your bottle is plastic (less shrapnel in the event of an explosion) and use a minimal amount of dry ice. I do not recommend this procedure. You can get fizzy fruit without harming yourself or anyone else.
- This goes along with the first point: don't seal dry ice into a closed container.
- Dry ice is very cold, so don't handle it or eat it.
- Freshly frozen fizzy fruit is the same temperature as dry ice (around -109°F) so allow it to warm a bit before consuming it.
- Slice strawberries, sugar them, and add a little bit of water to make a syrup. Stir dry ice into the mixture to carbonate the berries and syrup. Use the carbonated strawberries as a topping for strawberry shortcake or ice cream.
- Slice apples and strawberries. Carbonate them with dry ice. Add them to champagne.
- Slice a banana. Make it fizzy then coat it with chocolate. Allow the banana to warm slightly before eating it.
