milk based coffee
The intent is pretty clear
The clean palette recipes are started at the starting for a reason. They had mostly single spices, were clear and simple on taste.
If you would have tried them out then chances are very high that you would be now be able to differentiate the different tastes of the spices and what spice goes how
example
The subtle difference between the nutmeg and mace in taste
the warmth of the AllSpice which gets added to the coffee - If warmth in taste sounds OK and not like some thrown in adjective you would are in a position to feel a taste
Anyways so now the milk based ones are here. These mostly take a blend of spices. The milk blends and amalgamates all the flavors as a common base. Water is not very good at this act.
So now the tastes your palette ill experience are a tad more complex and twisted in nature. So if you would have gone through the clean palette stage these recipes would be much much more enjoyable as you would see a whole new world of tastes intermingling in front you.
For us Indians this is much more richer and rewarding because most of the spices are mainly restricted in our cooking to savory dishes , biryanis etc
In a milk based coffee beverage its a whole new setting
Go ahead take yourself on a ride of flavors and tastes.
End of day the most important thing is, spice or no spice, you enjoy your coffee.
