Quick answer
Chen Pi (陈皮) is sun-dried tangerine peel aged for at least three years. Aging mellows bitterness and develops a deep, sweet citrus aroma. It is traditionally used in Traditional Chinese Medicine (TCM) to regulate qi and support digestion, and is used in red bean soup, braised duck and after-meal tea.
Key takeaways
- Minimum 3 years to be called chen pi; 10+ years is premium.
- Soak 20 minutes and scrape pith for less bitterness.
- A pinch balances rich tonic herbs like shu di.
How chen pi is aged
Mandarin peels are cut into three petals, sun-dried, then stored in a dry, ventilated space. Each year the essential oils oxidize and mellow — which is why aged chen pi commands a premium.
How to use it
Soak 20 minutes in warm water, scrape away excess white pith, then slice. Add to red bean soup, braises, congee, or steep 1–2 pieces as a digestive tea after meals.
Frequently asked questions
Is chen pi the same as orange peel?
No. Chen pi comes from specific mandarin varieties and must be aged; fresh orange zest has a sharper, different flavor.
How should I store chen pi?
In an airtight container away from moisture and light. Properly stored, it keeps improving with age.
