TO MAKE PASTRY CREAM

Instructions
 

CONVENTIONAL METHOD

  • Add cream and vanilla to a small saucepan. Whisk over medium heat until it reaches a low simmer and remove from heat.
  • In a separate bowl whisk together sweetener and egg yolks. Whisk into the cream mixture.
  • Return to the heat and continue whisking until custard thickens and coats the back of a spoon. Serve warm or chill for later.

To Make Pastry Cream

  • If making Pastry Cream; whisk through butter and xanthan gum after taking off the heat. Push through a sieve to remove any lumps.
  • Leave to cool at room temperature then press cling film over surface of pastry cream and transfer to the fridge. Refrigerate 2-3 hours.

THERMAL METHOD

  • Insert Butterfly. Add the ingredients to the mixer; cook 9 min/90 ̊C/speed 4.
  • If making Pastry Cream, add the butter and xanthan gum to the custard in the mixing bowl. Mix 1 min/speed 4. Scrape down the sides of the bowl and mix again 30 seconds/speed 4.
  • Leave to cool at room temperature then press cling film over surface of pastry cream and transfer to the fridge. Refrigerate 2-3 hours.

Notes

This recipe is suitable to be made in larger batches if preferred. You can double, triple or quadruple the recipe if you have a large family.
When cooking with the conventional method be careful to keep the temperature low. A custard is mainly eggs and if overheated, you will end up with an eggy custard or worse still, sweetened scrambled eggs!
Keep whisking continuously and don’t leave the custard unattended while on the heat. It helps to keep the consistency smooth if you are whisking and taking note of the thickening of the keto custard.
I have a recipe for Hot Choc Powder in The Healthy Family cookbook.
When pastry cream cools, it can form a skin on the surface. Pressing cling film over the surface stops this from happening.
The custard can be stored in an airtight container in the fridge for up to 3 days. I don’t recommend freezing it as it can separate when defrosting, and it’s much better freshly made.
