Man, everyone else rated this really high. I am glad I read the reviews first as it salvaged this one for me.
I prepared this with 1 tsp of powder and 8 ounces of cold 2% milk. I thought the taste was on the weird side. It was banana-ish but then there was another taste like rose water. It wasn’t real strong but distracting. I added a little sweetener (equivalent to 1 tsp of sugar). This reduced the rosewater note and brought the banana into the marshmallow candy range mentioned by others. With sweetener it is sweet but not too sweet for a dessert treat.
Sometime soon I plan to make this again and add ice cream, along with a drizzle of chocolate and caramel. This has potential!
