Instructions
Step 1
Let the frozen puff pastry thaw at room temperature until slightly softened. Once placed in the tart pan, prick it with a fork and let it rest in the refrigerator.
Step 2
Remove the seeds and fibers from the pumpkin, cut it into bite-sized pieces, and place them in a microwave-safe bowl. Add vegetable dashi, cover with plastic wrap, and heat in a 600W microwave for 2-3 minutes. Mash the pumpkin while still hot, mix in [A], and let it cool.
Step 3
Pour the mixture from step 2 into the tart shell from step 1. Bake in a preheated oven at 392°F for 10 minutes. Lower the temperature to 356°F and bake for another 30-40 minutes.
