I was surprised this morning to find Sunland Produce had a huge display of 1 liter bottles of 100% Extra Virgin Avocado Oil, and at the very reasonable price of US $7.99/liter. The bottles had no point of origin but I was able to track it down to Mexico - which is reasonable since Mexico is the largest avocado producer in the world.
The bottle said it would go to 491°F/255°C, but I took it up to 500°F (the highest I can measure accurately) with no smoke. The heated oil tasted a little less "virgin" but did not have an "off" or damaged flavor, though I admit it was above 491°F for only a few minutes. Refined avocado oil should go to 520°F.
The flavor of this oil is reasonable neutral but somewhat buttery. The health profile is nearly identical to Olive Oil, just 5% more saturated and 5% less monounsaturated.
I think I'll buy some more while they have it. The bottle says "best before Jan 2013" so it doesn't look like it spoils quickly.
