For Halloween, we attempted to break the record for the world's loudest scream—the acknowledged "Scream of Ice Cream." To coincide with the attempt we created the world's first "ice cream soup," a bowl of steaming hot 
pumpkin soup with a scoop of pumpkin ice cream dropped in the middle. I loved it, but it left everyone else in meltdown. In the end we ran out of time to stage the world-record 
attempt, and killed off ice cream soup, but we kept spiced pumpkin ice cream alive.

　　

Ingredients

About 2 cups

　　1 cup whole milk

　　1/2 cup heavy cream

　　2 egg yolks

　　1/2 cup plus 1 tablespoon superfine or granulated sugar

　　1/3 cup canned pumpkin

　　1/2 teaspoon ground cinnamon, plus extra for dusting

　　drop of vanilla extract

　　dash of dark rum (optional)

　　

Step 1

1. Pour the milk and cream into a large saucepan and heat gently, stirring occasionally, until the mixture begins to steam but not boil.

　　

Step 2

2. Meanwhile, whisk the egg yolks in a heatproof bowl until smooth. Add 1/3 cup of the sugar and whisk until pale and slightly fluffy. Gradually and slowly, pour the hot milk into the egg mixture while whisking continuously to prevent the eggs from scrambling. Return the mixture to the saucepan and place over low heat, stirring frequently, until the custard thinly coats the back of a wooden spoon. Do not let boil.

　　

Step 3

3. Pour back into the bowl and set aside for about 30 minutes, stirring occasionally, until cooled to room temperature. For more rapid chilling, fill a sink halfway with cold water and ice and place the bowl of mixture in it for 20 minutes. Never put the hot mixture into the refrigerator.

　　

Step 4

4. Put the pumpkin, cinnamon, vanilla extract, remaining sugar, and a dash of rum, if using, into a blender or food processor and blend until smooth. Add to the chilled custard and whisk well. Pour the mixture into an ice cream machine and churn according to the manufacturer's instructions.

　　

Step 5

5. When the churning is completed, use a spoon or spatula to scrape the ice cream into a freezer-proof container with a lid. Freeze until it reaches the correct scooping texture (at least 2 hours). Dust each portion with a little ground cinnamon before serving.
