In Japan, where we have 4 seasons, people tend to value the custom to use seasonal ingredients or add some seasonal taste to their cooking. Japanese dishes are delicate, in which you can find the elements to satisfy the five senses – taste, sight, smell, etc.
Today we focus on the sense of “smell”, featuring especially “sesame”, whose season is September to October, and tell you how to grind sesame and extract its rich smell.
What is sesame?
Sesame, originating from Africa or India, is a seed containing oil. This oil, when extracted, is sesame oil. Sesame oil is used in cuisine of various countries such as Japan, China and Thailand.
The main attraction of sesame is its savory rich smell. Not only sesame oil but also grinded sesame on tofu or with sweet Miso (soybean paste) enriches the flavor of dishes themselves. For this reason, sesame is an essential ingredient for Japanese dishes.
How to Grind Sesame
There are 2 important points to optimize the flavor of sesame. One is to grind sesame just before eating them. The other is to use an appropriate Suribachi mortar to grind sesame.
Sesame has richest flavor right after grinded and has less smell over time. So, it is better not to grind large amount at a time but to grind the amount to be used. The same applies to other flavorful food including Wasabi, Japanese mustard and pepper.
Using an appropriate Suribachi mortar is also important. In particular, we need to choose right size. There are a variety of size for Suribachi mortars.
When the size is not right, it cannot work well or cause stresses. You may use bigger size, but it would require more space for storage. So, you should choose the one that fits the purpose.
