Raisins are foods made from dehydration of grape fruit by solar heat or artificial heating. It is high in sugar and is a typical high-energy nutrient. Raisin production is also very strict on grape varieties and climate.


How to make raisins?


1. Set the oven temperature to around 110 degrees Celsius and preheat for 15 minutes. After the oven is preheated, add the grapes, otherwise the quality of the raisins will be affected.


Grapes need to be roasted at this temperature for about 4 hours before turning into raisins.


If you want to take it slow, turn the heat to 65C and bake for about 36 hours.


Although it takes longer, it also reduces the risk of over-baking or over-drying.


2. Please choose no core when buying, don't spit core when eating.


Cut off one by one, leaving a small branch about 2mm long at the top.


Scrub lightly with a moderate amount of cornstarch.


Wash off any stains on the surface of the grapes. After scrubbing, rinse and drain.


3. Grease 2 rimmed baking sheets with a very small amount of vegetable oil and spread grapes evenly on top.


Try not to let the grapes touch each other.


If you don't want the grapes to get greasy, you can use parchment paper instead. Although there must be space between each grape, contact with each other will not affect the finished product.


4. Place the grapes in the oven and roast for about 4 hours, or until crumpled. Raisins must be dry, but not shriveled. During the roasting process, check the grapes from time to time to avoid mistakes.


5. Remove raisins from oven and cool. Once the grapes are dry enough, carefully remove from the oven and let cool for at least 30 minutes.


6. Once the raisins are completely cool, store them in the refrigerator to keep them fresh.
