Yumm!! I used all rice milk. I don't do soy and suggest you don't either! I skipped the pepper out of preference and used local honey rather than sugar, but I can see sugar would be good. It comforted me in some way and took the chills away. I would make this another time.
I own the Vegan Sourcebook and this is one of my favorite recipes. Thanks for adding it online :-) Must note that I like using vanilla soymilk, too. And if you aren't fussy about the taste (or price) of saffron, it can be left out and the drink will turn out lovely anyway.
This is lovely and soothing for nighttime. The saffron gives it a slight creamy-golden color and a really nice flavor. Instead of grinding the cardamom seeds, I just pierced some cardamom pods and put them in. I found that, up to a point, adding sugar brings out the spice flavors.
