Toasted sesame oil is made by extracting oil from sesame seeds that have been toasted.
The Process of Making Toasted Sesame Oil
The key difference between regular sesame oil and toasted sesame oil lies in the treatment of the sesame seeds before oil extraction. The process involves these main steps:
- Toasting the Seeds: Sesame seeds are heated, usually through roasting or light frying, before pressing. This toasting process is crucial for developing the characteristic flavour and colour of toasted sesame oil. The heat changes the chemical composition of the seeds, enhancing their taste.
- Extraction: Once the seeds are toasted and cooled, the oil is extracted using various methods such as cold pressing or expeller pressing. The chosen method can influence the final quality and flavour profile of the oil.
- Filtration: The oil is then filtered to remove any remaining solids and impurities, resulting in a clear, dark-coloured oil.
Key Differences From Regular Sesame Oil
| Feature | Toasted Sesame Oil | Regular Sesame Oil |
|---|---|---|
| Seed Treatment | Seeds are toasted before extraction | Seeds are not toasted before extraction |
| Flavor | Strong, nutty, roasted flavour | Mild, subtle flavour |
| Colour | Darker colour | Lighter, pale yellow colour |
Impact of Toasting
The toasting process not only changes the flavour profile but also affects the color and aroma of the oil. The heat helps to release volatile compounds that give toasted sesame oil its unique characteristics. As referenced, heating the seeds before extracting the oil is what gives it that "whole different flavour" and darker colour compared to regular sesame oil.
