Based on this one, I think:
Operating without a traditional rolled pastry shell requires relying on flour settlement and starch gelatinization to form a cohesive base during baking. Blending all components except the liquid first prevents lumps from forming in the denser starches and spices. Pouring the coconut milk through the feed tube while the motor runs incorporates air uniformly into the batter, which supports the custardy texture.
Utilizing canned pumpkin guarantees a consistent moisture level that fresh winter squash cannot reliably match without prior roasting and draining. Proper cooling on the counter followed by refrigeration transforms the soft custard into a sliceable dessert.
