This one time at Dainty Sichuan, the waiter who scooped our Sichaun pepper from the boiling fish dish and asked if we were wanting to take the chillies and peppers home. Out of excitment I agreed but I had no idea what I was going to do. At work the next day there was basil oil that needed to be made for service... and thats when this idea came into mind! Sichaun pepper oil, heated to 75 degrees and strained through a Chux cloth twice. ... thank you wishful thinking waitress at Dainty Sichaun!
