Raisins are a delicious natural snack that can be eaten straight or added to various recipes, such as oatmeal cookies. Besides being versatile, raisins are very easy to make. Simply dehydrate the grapes in the sun, in the oven or in a dehydrator and the raisins will be ready in a matter of seconds.

Steps

Method 1 of 3: Dehydrating Grapes in the Sun

Make Raisins Step 1

Step 1. Take out the larger handles and wash the grapes well

It is not necessary to remove all the stems from the grapes, but it is very important to cut the larger ones out. Then wash the berries well under running water.

You can also use a natural vegetable detergent to wash the grapes. Overall, however, water is more than enough

Step 2. Evenly spread the grapes on a baking sheet and cover them

Use a griddle made of wood, straw, bamboo or plastic so that the air has room to circulate. Spread the grapes well so they don't clump together and cover them with a dish towel.

  • You can also cover the grapes with a pillowcase if you don't want to use a dish towel.
  • Coverage should be extensive enough to protect the grapes from insects while they are dehydrating.
  • Use a cloth heavy enough not to be carried by the wind. Fasten it in the corners with a few weights if it is too light.

Step 3. Leave the pan in the sun in warm, dry weather

Place it in a location that receives plenty of natural light throughout the day. Do this only if the weather is hot and dry. The hotter and drier it is, the faster the grapes will dehydrate.

  • Grapes will take time to dehydrate if you leave them exposed in cold, cloudy or humid weather. They may not even completely dehydrate. Take the roasting pan outside when the weather forecast predicts sunny days with low humidity and temperatures around at least 25 °C.
  • If you live in a place that tends to have fog and dew at night, take the baking pan indoors in the late afternoon and put it back outside in the morning.

Step 4. Leave the grapes outside for three to four days, turning occasionally

Grapes can take up to 96 hours to completely dehydrate, depending on the weather and how hydrated they were. However, they must be exposed to the sun for at least three days. Turn them twice a day so that both sides of the grapes dehydrate evenly.

  • Taste one or two grapes after three days to see if they are ripe. If you think they are dehydrated enough, take them inside. Otherwise, leave them in the sun for another day.
  • Grapes can be exposed to the sun for up to five days. It is not necessary to leave them outside any longer.

Step 5. Take the dried grapes inside and store them in a container with a lid

Once the grapes have turned into raisins, take the baking pan indoors and store the raisins in a container with a lid. Refrigerate the pot or put it in a cool place.

Some options for raisin containers are an airtight bag, a tupperware, and a glass preserver that is protected against the ingress of oxygen

Method 2 of 3: Baking the raisins in the oven

Make Raisins Step 6

Step 1. Preheat oven to 100 °C

Light the oven to 100 °C and allow it to preheat for 15 minutes. Do not put the grapes in the oven until it is at the correct temperature. Otherwise, the raisins might look bad.

At this temperature, the raisins will be ready in four hours. If you prefer to prepare them more slowly, heat the oven to 65 °C and roast the grapes for 36 hours. The preparation time will be much longer, but the raisins will have less risk of overcooking or becoming too dry

Step 2. Wash the grapes and remove the stems

Wash the grapes well under running water and remove the larger handles with your fingers or with the help of scissors. Throw away the grapes that are spoiled.

You can also use a natural vegetable detergent to wash the grapes

Step 3. Grease two baking sheets with oil and spread the grapes on them

Lightly grease two baking sheets with a little vegetable or canola oil. Then distribute the grapes evenly over the pans, taking care that they don't touch each other.

  • You can also line the baking sheets with parchment paper if you prefer to leave the grapes without oil.
  • Although the grapes should be distributed so that there is a little space between them, the raisins will still be good if the grapes touch.

Step 4. Bake the grapes in the oven for four hours or until they are wrinkled

Ideally, the grapes are very dry, but slightly succulent. Check them out once in a while to make sure everything is going well. Take the raisins out of the oven in less than four hours if they're already in the right spot.

The cooking time of the grapes will vary depending on the size of the fruit and the level of dehydration desired. Larger grapes will take longer than smaller ones to dehydrate

Step 5. Take the raisins out of the oven and let them cool

Once the raisins are dry enough, carefully take them out of the oven and set them to cool for at least half an hour. If any of them stick to the baking sheet, use a very thin metal spatula to loosen it.

Step 6. Store the raisins in a lidded container in the refrigerator

After the raisins have cooled, place them in a container with a lid and refrigerate them to keep them fresh.

Raisins should be refrigerated for up to three weeks

Method 3 of 3: Using a Dehydrator

Make Raisins Step 12

Step 1. Wash the grapes and gin them if necessary

Thoroughly remove dirt from the grapes under cold running water before placing them in the dehydrator. If the grapes have seeds, cut them in half and dig them out before taking them to the machine.

  • It is not necessary to open the grapes if they are seedless.
  • You can also wash the grapes with a natural vegetable detergent.
Make Raisins Step 13

Step 2. Spread the grapes on the dehydrator trays

It is not necessary to distribute them evenly. It's okay if they keep touching each other. However, be careful not to put too many grapes in the machine. Otherwise, you could end up hampering dehydration.

Strictly follow the dehydrator instruction manual so as not to exaggerate the amount of grapes

Make Raisins Step 14

Step 3. Turn on the dehydrator at 60 °C

This is the temperature normally used to dehydrate grapes. If your dehydrator has a specific function for fruit, select it.

It is possible that the instruction manual recommends a temperature for dehydrating uses. Follow the manufacturer's recommendations, if applicable. Otherwise, turn the dehydrator on at 60 °C

Make Raisins Step 15

Step 4. Dehydrate the grapes for at least 24 hours

Grapes usually need at least 24 hours to dehydrate. Some, however, may need a little more time. Take a look at the grapes every two hours or so and taste them. Take them out of the dehydrator if they're to your liking in less than 24 hours.

  • Small grapes usually take less than 24 hours to be ready. Have a look at the grapes more often if they are small so you don't risk burning them.
  • Avoid dehydrating the grapes for more than 48 hours.
Make Raisins Step 16

Step 5. Take the grapes out of the dehydrator and store them

Once the grapes are in the right spot, take them out of the dehydrator and let them cool completely. Then transfer them to a container with a lid, such as a glass jar, or a ZipLoc-type bag and keep them.

Prepared this way and stored in a lidded container in a cool, dry place such as a pantry, raisins can last for several months

Tips

  • If the grapes are too ripe, they may take a long time to dry or even rot before dehydration. Ideally, use green grapes that are already a little sweet.
  • Watch for signs of dampness and decay. Remove spoiled grapes from the tray immediately and spread the fruit nearby to dry. Once dehydrated, the grapes should be small and wrinkled, not rotten and limp.
  • Those who work making raisins usually hang the bunches of grapes by a string or wire to put them to dry. The method is more difficult than using a tray, but it is far more effective as it allows more air to circulate between the fruits.
