Start by placing the heavy cream, half and half, and custard mix in a heavy bottomed saucepan.
Heat the mixture until it comes to the boil while whisking continuously.
Once the mixture has come to the boil, maintain a boil while whisking constantly for 30 seconds.
Next, remove it from the heat and add your flavoring of choice.
Once the flavoring has been added, blend the custard with an immersion blender for 30 seconds.
While the mixture is still hot, pour the crème brûlée into serving vessels of your choice.
Finally, place your crème brûlée in the refrigerator and chill until it has set, which usually takes about 5 hours, but overnight is best.
Note: Since the crème brûlée is fully cooked on the stove top, this allows for presentation in vessels that could not normally be used in a traditional hot water bath.
Once your crème brûlée has set up, sprinkle the top with sugar and brûlée with a torch for final presentation.
Store your fully set Itaberco Crème Brulée in an airtight container in the refrigerator for up to 5 days.
