right. you need to have different spices each time. and I'm sorry to tell you that those spices are probably not enough. I use 5 or so spice blends--each one has 5 or so spices. So I have about 25 spices. You had 7.
you can tell if the spices are not enough if you can identify any of them. If you could tell there was vanilla in the drink, for instance, then there wasn't enough. I think spice blends work better than spices because you are unlikely to have had them anywhere else. Vanila, nutmeg, and chinese 5-spice are flavors you may have had in food you buy already spiced (e.g., vanilla ice cream). Whereas a spice blend you buy (at least, an uncommon one) you are unlikely to have ever had before.
