Kiwi fruit has a wonderful flavor and although it's native to China, it's grown all over the world. Fruit is much better when it's fresh, but you can also freeze it if you want to save it for another day.
Part 1 of 3: Peeling and Cutting the Kiwi
Step 1. Take a good look at the kiwis to see if they are ripe
Kiwifruit can spoil during storage, so it is very important to keep them in the best possible condition. Look for fully ripe kiwi fruit, meaning kiwi fruit that sags a little when squeezed. If it's hard, wait for the fruit to ripen before freezing it.
- Size in kiwi fruit is not related to degree of ripeness.
- To ripen the fruit faster, place it in a paper bag.
Step 2. Cut the stalk of each kiwi fruit
The stalk is located on top of the fruit and looks like a piece of wood. With a knife, cut the stalk and the skin around it, revealing the fruit inside. To conserve as much of the kiwi as possible, make very thin cuts in the skin.
Step 3. Place a spoon under each kiwi shell
With the stalk removed, look for the part where the pulp joins the husk. Push a spoon into this area with the curved side out. The goal is to push the skin upwards, not take out pieces of the flesh, so make an effort to avoid cutting the fruit.
Step 4. Turn the spoon to peel the fruit
When the spoon is completely inside the kiwi, slowly turn the utensil around the entire pulp. This will remove the skin and create a gap between it and the pulp. When finished, the kiwi will slide out of the shell easily.
Step 5. Cut the shelled kiwi fruit into several pieces
For best freezing results, cut the pieces of fruit to the thickness you would use if you were going to eat them today. If there is still some of the husk in the pulp, remove it now.
Whole kiwifruit often swell and crack during the freezing process, a problem that pieces of fruit don't have
Part 2 of 3: Preparing the freezing platter
Step 1. Cover a baking sheet or a platter with a piece of parchment paper
Take a baking sheet or flat serving dish that fits inside the freezer. Clean it, if necessary, and cover it with wax paper or non-stick film.
Look for wax paper in supermarkets or grocery stores
Step 2. Place the kiwi slices on the platter
The individual pieces should not touch each other, but you can place them very close together to save space. If necessary, use other platters to accommodate all the pieces of fruit.
Step 3. Cover the kiwi fruit with sugar (optional)
To better preserve the kiwi's color and flavor, you can top it with a thin layer of granulated sugar. To do this, pick up the sugar with your fingers and sprinkle over the fruit, letting it spread evenly. For every pound of kiwi you have, plan on using 230 g of sugar.
In place of sugar, you can use a commercial fruit preserving powder
Step 4. Cover the kiwi pieces with parchment paper
To keep the fruit moist, place a piece of parchment paper or non-stick film over the slices. Press the paper so there is no space between it and the kiwi. If desired, wrap the entire dish in protective paper to cover any additional air bubbles.
Part 3 of 3: Storing the Kiwi
Step 1. Make a space in the freezer that is large enough to accommodate the serving dish
Try to make the space as flat as possible so that the kiwi pieces don't lose their juice or slide over each other.
Step 2. Leave the fruit in the freezer until completely frozen
Smaller pieces should freeze for between four and six hours. Larger ones can take a day or, in some cases, longer than that. Remove the platter from the freezer when the kiwis are firm and no longer sag when squeezed.
To speed up freezing, remove as many items from the appliance as possible
Step 3. Transfer the fruits to a freezing bag
For long-term storage, kiwis need to be kept in a container where they have minimal exposure to air. The cheapest solution is to place the pieces of fruit in a freezing bag, squeeze out the excess air with your hands and close it tightly. If you want a better but more expensive solution, try using a vacuum sealing device.
Since they are now firm, you don't need to prevent the pieces of fruit from touching each other
Step 4. Store kiwi fruit in the freezer for up to 12 months
Label the container listing the date the fruit was frozen and place it anywhere inside the freezer. Good kiwi slices should last up to a year, but check the fruit every month to see if it doesn't have mold or if it hasn't spoiled.
Step 5. Do not thaw before use
When thawed, the kiwi pieces can be soft and not very pleasant. To avoid this problem, use the fruit as an ingredient in vitamins, meat tenderizer, garnish and in other ways you can use it frozen.
