Aromatic ingredients like garlic, ginger, green onions, chilies and spices. These ingredients are typically added to the oil first to infuse it with flavor. You won't need much; a few teaspoons to a tablespoon of total aromatic ingredients per person adds a serious amount of flavor.

Much like French food, which relies on a roux for a perfect bechamel sauce or beef bourguignon and involves butter cooked with flour, Chinese and Cantonese cuisines use cornstarch to thicken sauces. However, it's predominantly added at the end of the cooking process rather than at the start.

The most readily available sauce-thickener is flour. For a too-thin sauce, try adding a slurry (equal parts flour and water, whisked together) or beurre manie (equal parts softened butter and flour, kneaded together to form a paste)—both are ideal thickeners for rich and creamy sauces, such as steak sauce recipes.

If you're dealing with a stir-fry sauce or gravy that's just a little too runny, make a cornstarch slurry with two parts water and one part starch (adding it directly to your sauce will cause it to clump), then whisk it into your hot sauce, keeping in mind your sauce will further thicken as it cools.
