Tips
1. To make the most simple, you can use sesame paste as the dipping sauce of hot pot.
2. No need to add too much salt, because sesame paste, peanut butter, and peppercorns already have some flavor.
3. You can purchase Sichuan peppercorn oil directly from supermarkets. But the freshly made Sichuan peppercorn always taste better than a package one.
