Example Input: This is the microwave version of the original. I cannot stand it. The noodles have no flavor at all; and to me it is not spicy. I will not order any more of this product!
Example Output: 1

Example Input: Ordered on a whim.  My first "Grove Square" purchase.  Great for the family's occasional cocoa desire.  Being a K-Cup it's fast and easy.  Was a little worried the cocoa might leave some after taste in my coffee, so far so good.  Great cup of dark, rich cocoa.  Maybe could taste a LITTLE better if it was from a gourmet brand you mix yourself with steamed milk.  The ease and simplicity, and lack of clean up, make this a better option for me.  Will order again.  Nice to see it on subscribe and save.
Example Output: 5

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