Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Smells great and is very convenient but I feel like it loses its fragrance very quickly upon cooking. I was fairly liberal in using it in a dish the other day and it seems imperceptible after cooking (and no other strong or competing flavours were used). Smells great out of the jar though and might be more suited to salad dressings and the like.
Also a minor note but worth mentioning - it's a product of China; I didn't see any mention of this in the product listing.
