Is this made out of nuts?

We went to a restaurant that we like called the Zum Lowen (The Lion). Well we have this spread that comes out with the bread not knowing what it was we would always debate about it. It really was yucky, so we all have only had one bite each time. Anyways, I asked the waitress and she said she didnt know how to say it but, when I took a guessed that it was made out of nuts -(which I had to explain what I ment by nut- using hand gestures nut falling from tree.) She laughed at my guess, and so did the other man a couple tables away. A while later she comes back and has a piece of paper with the a translation of the word she said the spread was. "crackling fat" from a pig. we are thinking pork rinds and fat. We all had a good laugh over this.
