 Hunan cuisine, on the other hand, is often spicier by pure chili content and contains a larger variety of fresh ingredients.Both Hunan and Sichuan cuisine are perhaps significantly oilier than the other cuisines in China, but Sichuan dishes are generally oilier than Hunan dishes.Another characteristic distinguishing Hunan cuisine from Sichuan cuisine is that Hunan cuisine uses smoked and cured goods in its dishes much more frequently.
