Use 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
- You want the dry ice to be in relatively 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 whacking it (gently) with a hammer. You want to break it into pieces, not pulverize 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 (I slice strawberries, too).
- Place some dry ice pellets in a bowl. Set the fruit on the dry ice. You can add more dry ice if you wish. I like to play with my food, so I would stir the mixture, but it's not really necessary.
- 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 (makes interesting ice cubes). The fruit will remain fizzy as it thaws, but it should be used (frozen or thawed) within an hour or so because it will lose its bubbles.
- There are videos that show people carbonating fruit by sealing dry ice and fruit in a plastic bottle. This is not a particularly 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 risking a trip to the emergency room.
- 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 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.
