Never been to a Trader Joe's, Shel, so am not familiar with that product.
Is it a varietal oil, made from Kalamata olives? Or is it what in Sicily (and maybe other places) is known as black oil. If the latter, you can easily make it yourself:
Start with equal parts, by weight, of pitted black olives (I happened to have used Kalamata, when I tried this) and evoo.
Partially dehydrate the olives in a 170F oven for about four hours.
Puree the olives and oil in a food processor, filter out the solids, and reserve the oil.
You want to use this fairly quickly, so don't make too much at once. Three or four ounces each of oil and olives is a good quantity at any one time.
