This is exactly what I was looking for -- but it is expensive here. I have found achiote paste at a local Mexican grocery for much less. However, when I was first looking for this, I was glad to find it at Amazon, and willing to pay the extra.  It's the real deal. There is no other flavor like this. For those who have never used this, it comes in a very firm block, and you must break off pieces to mix with oil and/or lime juice to use for a marinade. Blending with those ingredients in a small food processor makes it easier to mix.  I only used about 1/3 to 1/2 of a block for a whole chicken. But I'm a novice with this, and still learning, so listen to tips from others who know more than I do.
