I just got a sample of Sunbutter Creamy Sunflower Seed Spread in the mail, and I of course had to try it right away. SunButter Cream is of course peanut free (made from sunflower seeds), so there's no worry about peanut allergy reactions and it's gluten free too.
Although I've tasted various peanut and almond butters, I've never tried sunflower butter. In order to fully appreciate the flavor, I ate it with a spoon, straight from the little 1.5 ounce pack it came in (to be honest, I do that with regular nut butters as well).
In terms of taste, it's hard to begin to describe this stuff. Before I try to do just that, let me just say it's delicious. It has some of the earthiness of almond butter, but the flavor is slightly different. It definitely tastes like sunflower seeds with some sugars added - in the best way possible. It's creamy and thick, as well as somewhat grainy, which gives it a little texture (although it's still smooth), and I bet it would taste wonderful in PB&J as well.
The ingredients are pretty spectacular, too - sunflower seed, sugar, mono-diglycerides to prevent separation, salt, and natural mixed tocopherals to preserve freshness.
