Is a neutral oil that has been infused with whole or crushed red chile flakes. However, chile oil can be used in Asian cuisines to make use of garlic, scallions, and Sichuan peppercorns. 

You can make a sauce that is rich in flavor and aroma by adding herbs, spices, citrus peels, or other ingredients. High-quality spicy chili oil can be found online. 

These are just a few ways you can use it.

1. Serve it with sweet potatoes

Instead of using butter, add a tablespoonful of chile oil to baked sweet potatoes.

2. It can be drizzled over tomatoes

This fiery version of a classic salad uses Chile oil instead of olive oil.

3. It can be used on noodles

This traditional Chinese cold-noodle dish is enhanced by the addition of Sichuan peppercorns that are incredibly fragrant and sesame seeds that add a unique flavor to the chile oils. (A great make-ahead lunch, btw.)

4. It can be used as a hot sauce

Creamy dairy-based soups like bisques and chowders benefit especially from a little spice.

5. Combine it with quickly-blanched vegetables

There's a new green bean dressing, so forget about amandine.

6. It can be added to salad dressings

You can add spice to an already simple dressing by substituting the oil for the needed. This is especially useful for salads with sweet elements, such as carrots or dried fruits.
