There are several videos online, but (at first, at least) I didn't find any that I liked. This image, however, kept me on the hunt for the perfect video and recipe:
I found a number of different variations. Here's a link to a simple one (I loved the fact that so many people in the comments section noted that they had also read The Red Pyramid and gone on a search for the recipe). This one uses corn starch with vanilla for flavor and sugar to sweeten it. I've seen other flavors (rose water, for one) and some people prefer honey to sugar. A number of people have commented that they would prefer to omit the coconut topping (or pistachio, in other recipes), because they don't care for chewy things in a drink, so that's a possibility, too.
I did, eventually find a video that did the trick for me. It's a bit longer than I prefer, but I like the fact that she gives you options.
I haven't tried this yet (I think I'd like to try the orange blossom water, and I don't have any of that...yet).
So, what do you think? Does this look like something you would drink on a cold day? I confess that I'm biased because I'm associating it with a favorite book, but I also find the idea of a warm, creamy vanilla drink appealing.
Have a great (warm) day!
