Sour Green Grape Roll-Ups

1. Blend
   Add grapes and lemon juice to a blender. Blend until completely smooth with no chunks remaining.
2. Spread
   Pour the mixture onto a parchment-lined baking sheet and spread evenly to about ⅛-inch thickness. Use an offset spatula to get an even layer — thin and consistent is key for uniform drying.
3. Dry
   Oven method: Bake at 140–170°F (60–75°C) for 4–8 hours. Dehydrator method: Set to 135°F (57°C) for 6–10 hours. The roll-up is ready when it is dry to the touch but still flexible and peels cleanly off the parchment.
4. Sour candy finish
   Mix the caster sugar and citric acid together in a small bowl. Once the roll-up has cooled, lightly dust or press the mixture onto the surface for a sweet-tart, candy-style coating.
5. Peel and cut
   Peel the roll-up off the parchment and cut into strips using scissors or a pizza cutter.
6. Store
   Store in an airtight container at room temperature for up to 1 week. Place parchment between layers to prevent sticking.

Tips: Spreading the mixture as evenly as possible is the most important step — thick spots will stay tacky while thin spots over-dry and crack. An offset spatula makes this much easier. Rotate the pan halfway through oven drying for even results.

Dehydrator vs Oven: A dehydrator gives more consistent results since the temperature stays steady. If using an oven, prop the door open slightly with a wooden spoon to let moisture escape and prevent the temperature from rising too high.

Swaps: Try with red or black grapes for a different color and slightly sweeter flavor. Concord grapes make an intensely flavored, deep purple version. Add 1 tsp fresh grated ginger for a spicy kick.

Sourness level: For extra sour, increase citric acid to ½ tsp. For a milder tang, reduce to ⅛ tsp or skip it entirely for a classic sweet fruit leather.

Storage: Keep in an airtight container at room temperature up to 1 week. For longer storage, refrigerate up to 3 weeks or freeze up to 3 months. Lay parchment between layers to prevent sticking.
