[Q]: I ordered this saffron after looking at seller feedback and assumed that since this is expensive it will be premium quality. But only after i put it in water for sometime, then the color of the flakes changed, and I realized that its a fake one. Dont waste your time on this.
[A]: Negative

[Q]: I decided to purchase this product based on a blog by one of the supplement oriented doctors on the internet, hyping erythritol as superior to xylitol, which I use regularly and find the closest to sugar in taste with almost no aftertaste and no side effects to my knowledge. The problem I find with erythritol is its lack of flavor. On cereal, I barely notice any real sweetness, even when I put as much as a tablespoon and a half on a normal size bowl. When I use Ideal, the name of the xylitol brand I use, it has the same sweetness as sugar in the same proportion. Don't get me wrong, erythritol isn't unpleasant, it just has very little sweetness relative to how much you use. Not worth the price unless you want just a hint of sweetness compared to what you get with sugar or xylitol.
[A]: Negative

[Q]: We were very excited to order the Blueberry Pancake mixes since we've loved many other Stonewall products. Unfortunately, we didn't like the pancake mix at all. We actually ended up throwing the pancakes away. The batter itself tasted terrible. It had this strong, almost sour taste and almost seemed carbonated/fizzy? We thought it would be better after we cooked it, but it wasn't. Also the blueberries were like hard little rocks. Too bad we bought the 3-pack, because now we have a lot of this product and won't be able to use it.
[A]:
Negative
