Back in the mid-80's we had a favorite family-run mexican restaurant here...
...that rendered its own lard. They made a ton of pork items (tamales, enchiladas, carnitas, etc.) so they always had enough lard for their beans.
I still have DREAMS about the taste of those beans! So creamy, smokey and PERFECT. They always told me it was because of the lard. I believed them, but even when I eat re-fried beans today that use real lard, it just isn't the same. I don't know why.
That restaurant is long gone, but I'll never forget those beans! If it was possible, I'd probably have them as my "last request". They were THAT GOOD...
