Szechuan peppercorn is featured in numerous savory meat, poultry, and noodle dishes. Ground, roasted Sichuan peppercorn is used to make an infused Szechuan peppercorn oil. Szechuan Peppercorns are not related to black peppercorns or chili peppers at all, but are a dried fruit grown in Asia. They have a mild lemony taste and create a tingling sensation in your mouth when eaten.
