As is most of the frozen stuff that you find in the groceries.
The original *big* Gilroy, Ca garlic grower, Christopher Farms, has jarred pressed garlic, as well as peeled and jarred cloves in grocery stores - a large part of their crop is now grown in Arizona and Mexico.
The Trader Joe's jarred pressed garlic is also pretty much from Mexico.
There is nothing wrong with that, for both enterprises, just stuff to know.
But the original recipe up there sounds amazing. !
