480ml heavy cream
240ml whole milk
180g pumpkin puree
4 large egg yolks (~72g total)
120–140g maple syrup
5g (1 tsp) vanilla extract
2–3 g (1–1½ tsp) Ceylon cinnamon
1 g (½ tsp) ground ginger
0.5 g (¼ tsp) nutmeg
1g (pinch) fine sea salt
Heat the whole milk, heavy cream, pumpkin puree in a saucepan over medium heat until steaming but not boiling.
In a bowl, whisk together egg yolks and maple syrup until smooth and pale.
Temper the yolks: slowly whisk in a bit of the hot milk mixture to the egg mixture.
Pour tempered yolks back into the pan with the rest of the milk, cream, and pumpkin.
Cook over medium-low, stirring constantly with a spatula, until the mixture thickens slightly and reaches ~75–80°C (170–175°F).
Remove from heat.
Add vanilla extract, Ceylon cinnamon, ginger, nutmeg, and salt. Stir.
Blend with an immersion blender or high-speed blender for ultra-smooth texture.
Pour into a container and chill in the fridge for at least 4–6 hours, ideally overnight.
Churn the cold base in your ice cream maker (usually 20–30 minutes) until it reaches soft-serve consistency.
Transfer to a container and freeze for 2–4 hours for scoopable texture.
Let sit 5–10 minutes at room temp before serving.
