Choose the right pumpkin: Pick small to medium sugar pumpkins. They’re sweeter, denser, and less watery than carving pumpkins, which means better texture and flavor.

Prep the pumpkin: Wash, halve, and scoop out the seeds and stringy bits. Save seeds if you want to roast them later.

Cook until soft: Roast cut-side down at 375°F (190°C) for 40–60 minutes, or steam in chunks until fully tender. Roasting boosts flavor and reduces moisture.

Drain excess moisture: Once cooked, let the pumpkin rest in a colander for 10–15 minutes. Press gently with a spoon to remove extra water.

Purée smoothly: Blend the flesh into a smooth purée. If it’s very thick, that’s fine; avoid adding water. Stir in a splash of lemon juice if you want to help preserve color.

Spread for drying: For a dehydrator, spread a thin, even layer (about 1/8 inch) on silicone or fruit leather trays. For an oven, line baking sheets with silicone mats or parchment and spread the purée the same way.

Dehydrate low and slow: Dry at 125–135°F (52–57°C) in a dehydrator for 8–12 hours, or in the oven at its lowest setting with the door cracked slightly for airflow. Rotate trays halfway through. Drying is complete when the pumpkin sheet is fully brittle, not tacky.

Cool and break up: Let the dried sheets cool completely. Break into pieces to prepare for grinding.

Grind to powder: Use a high-speed blender, spice grinder, or food processor. Pulse to your preferred texture. For the finest powder, grind in small batches and sift, then regrind any larger bits.

Condition the powder: Place the powder loosely in a jar for 3–5 days, shaking once daily. If you see clumps or condensation, it’s not fully dry—return to the dehydrator.

Store properly: Transfer to airtight containers. Label with the date. Store in a cool, dark place.
