The Custard in the Cooking Experience usually takes 7 minutes. The same ingredients work using the Thicken Mode but it takes 10-12 minutes depending on the quantities in the bowl. The benefits of the mode is that there isn’t a need to have a certain temperature of ingredients (it will work with either cold or room temperature milk) and there’s no need to check if it needs further cooking. If you use room temperature milk, the total time will be less and the Thermomix will adapt automatically. “
