Great for eating straight out of the box, not great for recipes requiring melted chocolate. Does not melt well, tends to dry out.

This baking soda works great for cooking or for health reasons. I take it for acid indigestion and heart burn. Just a 1 tsp in a half glass of water and it's gone. I use it to make my body more alkaline, so it's great for changing your pH level in your body!

Ex Output:
Positive

Ex Input:
I was excited to see that Amazon is selling 100% Kopi Luwak. However, these beans were a huge disappointment because they had no aroma and flavor at all. I'm guessing that they sent stale beans because there was no roast date printed on the bag.

Ex Output:
Negative
