Roasted Pumpkin Ice Cream – Recipe

Roasted Pumpkin Ice Cream

The ultimate plan for this roasted pumpkin ice cream is a plated dessert with grilled mochi, miso butterscotch, and a black sesame crumble; I haven’t finished the other components yet, but thought I would go ahead and share the ice cream recipe with you. Because it is intended for a dessert with Japanese flavors, I didn’t add any of the pumpkin pie spice flavors you might expect, and kept the pumpkin itself a bit subtle.

Although I’m calling this “roasted” pumpkin, I actually use a pressure-cooker technique cribbed from the Modernist Cuisine caramelized carrot soup. Cooking the pumpkin with a bit of baking soda increases the pH and encourages the Maillard reactions that add so much complexity to the flavor. If that doesn’t appeal to you, feel free to roast it in the oven instead (but don’t use the baking soda in that case, just roast plain pumpkin chunks.) Or if you want an even bigger shortcut, you could use  plain canned pumpkin puree.

I measure the brix (sugar percentage) of the base before cooking it, and it was about 28 which is just slightly high, so next time I’d either use maybe 20 grams less sugar, or add a bit more of the pumpkin puree.
