VIII. Thou shalt mix different temperatures
A great sandwich contains hot and cold elements within -- for example, hot smoked pork with cold Kimchi. Or try hot Vietnamese pork meatballs topped with cold carrot, daikon, and cold, crunchy cilantro. They call it the Mortadella at Lardo. Rick says that consideration of hot items and cold items will make the difference between an OK sandwich and a memorable one.
IX. Thou shalt question thyself
Before any sandwich goes on the board at Lardo it goes through a serious vetting process. Will it haunt someone's dreams until they can have it again? Have they elevated the sandwich just a bit? Did they make it their own by putting a small twist on it and surprise people a little? And, most importantly Rick says, “Is it $#@!@%! delicious?”
X. Thou shalt always strive for a more perfect sandwich
Even if you think you've found a sandwich combination so mind-meltingly awe-inspiring that it can only be paired with a drink from the Fountain of Youth and whatever the heck fruit was growing on the Tree of Knowledge, remember this -- never settle. There are so many more amazing sandwich combinations yet to discover.
