Gingerbread Custard Shake

Directions

1. 1Whisk the 2 egg yolks and the brown sugar simple syrup in a mixing bowl until smooth.
2. 2In a saucepan, combine heavy cream, cinnamon, ginger, and nutmeg. Heat until barely simmering.
3. 3Temper the eggs by slowly whisking 5 to 6 tablespoons of the hot cream into the egg mixture.
4. 4Pour the tempered egg mixture back into the saucepan and cook on low heat until the custard coats the back of a spoon.
5. 5Remove from heat, then whisk in the whole milk, vanilla extract, and salt. Refrigerate until fully chilled.
6. 6Pour the cold custard into the machine, select MILKSHAKE, increase coldness to level 10, and run for 25 minutes.

Tips

• Pour your liquid base into the Slushi bowl at room temperature, no need to chill it first, and let the machine do the work for 20 to 60 minutes depending on your kitchen's temperature.
• If your shake turns out too thin, it likely churned for less time than needed; run it for another 10 to 15 minutes and check the consistency before scooping.
• Stir the base well before pouring to make sure the brown sugar simple syrup, cinnamon, ginger, and nutmeg are evenly distributed throughout the cream and milk mixture.

Variations

• Swap the brown sugar simple syrup for maple syrup and add a pinch of cloves for a deeper spiced flavor that works well in fall and winter.
• Use half and half instead of whole milk to make a richer, creamier shake, or use 2% milk if you want it lighter and less heavy.

FAQ

Can I use pasteurized liquid egg yolk product instead of raw yolks?

Yes, pasteurized liquid eggs work fine and eliminate any food safety concerns, though the flavor will be slightly less rich. Use about 3 tablespoons of pasteurized liquid egg yolk as a substitute for two raw yolks.

What do I do if the shake won't freeze or scoop after an hour?

Check that your Slushi machine's bowl is properly frozen before you start; a thawed or warm bowl will prevent the liquid from setting. If the bowl is cold, your base may have too much liquid or not enough sugar, so try adding a tablespoon more brown sugar simple syrup next time.

How long can I store the finished shake in the machine?

The shake will keep well scooped and stored in a freezer-safe container for up to 3 days, though it's best enjoyed fresh. If you leave it in the Slushi machine, it will gradually separate and refreeze unevenly after a few hours.

Can I make this shake lighter or less rich?

Yes, replace some of the heavy whipping cream with whole milk or use half and half instead for a thinner base. The shake will churn faster and have a lighter texture, though it won't be quite as creamy.
