Step 1
- a.Prepare the Grapes
- b.Preheat your oven to its lowest temperature, ideally between 150-200°F (65-93°C).
- c.Carefully wash the grapes and remove them from the stems. Discard any bruised or damaged grapes.
- d.Pat the grapes completely dry with a clean kitchen towel or paper towels. This step is crucial to prevent steaming and ensure proper dehydration.

Step 2
- a.Arrange on Baking Sheets
- b.Line two large, rimmed baking sheets with parchment paper.
- c.In a large bowl, toss the dry grapes with the optional avocado oil to lightly coat them. This helps prevent sticking.
- d.Spread the grapes in a single, even layer on the prepared baking sheets. Ensure they are not touching to allow for maximum air circulation.

Step 3
- a.Dehydrate in the Oven
- b.Place the baking sheets in the preheated oven. Prop the oven door open slightly with the handle of a wooden spoon to allow moisture to escape.
- c.Bake for 8 to 12 hours. The exact time depends on your oven's temperature, humidity, and the size of your grapes.
- d.Check the grapes every 2-3 hours. They are done when they are shriveled, leathery, and have a chewy texture. They should not be wet or overly hard.

Step 4
- a.Cool, Condition, and Store
- b.Once dried, remove the baking sheets from the oven and let the raisins cool completely on the pan.
- c.For best results, 'condition' the raisins by placing them in a sealed glass jar, filling it about two-thirds full. Shake the jar once a day for 2-4 days. This redistributes any remaining moisture evenly.
- d.If you see condensation inside the jar, they need more drying time. Return them to the oven for another hour or two.
- e.Store the finished raisins in an airtight container in a cool, dark place for up to a month, or in the refrigerator for longer storage.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Use seedless grapes for the best experience. Thompson Seedless, Flame, or Crimson varieties are excellent choices.
- 2Ensure grapes are completely dry before placing them in the oven to prevent steaming and promote even dehydration.
- 3Propping the oven door open slightly with a wooden spoon is crucial to allow moisture to escape, which helps the grapes dry rather than bake.
- 4If your oven has a convection or fan setting, use it. This will improve air circulation and can reduce the drying time significantly.
- 5Test for doneness by removing a few grapes, letting them cool completely, and then tasting. They should be leathery and chewy, not wet or brittle.
