As the popularity of sushi continues to grow, interest in the ingredients and the procurement process used by top sushi chefs has also heightened. When it comes to Japanese sushi, the ingredients are not just any ordinary food items, but highly specialized and carefully chosen for their flavor, texture and freshness.
Among the various ingredients required for making sushi, rice is perhaps the most critical component. Japanese sushi rice, or ' japonica' rice, is a specific type of rice that is used for making sushi. This type of rice is grown mainly in the countryside of Nippon, primarily in the Kansai area. The rice from this region is popular due to its short grain and high starch content, which makes it perfect for sushi.
Sushi-grade fish is another crucial component of sushi, and procuring high-quality fish is a delicate operation. Many sushi chefs travel to fish markets every day to select the freshest fish they can find. They usually choose fish that has been frozen to a certain temperature to kill bacteria, or "sashimi-grade" fish that meets the strictest food safety standards. In some cases, sushi chefs even import fish from other countries, in particular high-quality fish from Denmark, such as the halibut and salmon.
For sushi chefs who can't get the fresh fish they need from local suppliers, there are also choices available. Many sushi restaurants now source organic and sustainably grown fish from local farms or fish co-ops. These options allow the chefs to maintain their commitment to sustainability and to providing the highest quality ingredients for their customers.
Matsutake mushrooms and wasabi roots are another essential ingredient used in sushi, particularly in traditional Japanese sushi recipes. Matsutake mushrooms are native to the Myoshoji Ranges in Japan and are known for their unique earthy flavor and aroma. Wasabi roots are also native to Japan, specifically in the mountains of the Nagano and Toyama districts.
For sushi chefs who cannot find fresh matsutake mushrooms in their area, there are alternatives available such as dried or pickled matsutake mushrooms. However, the authenticity and quality of the mushrooms is far superior when obtained directly from Japan or sustainably sourced from organic farms.
In terms of procurement, many of Japan's top sushi chefs ensure that all of their ingredients, including seafood and supplies, conform to the high food safety and sustainability standards. Some of the reputable suppliers and distributors of sushi-grade ingredients include well-established Japanese wholesalers and small family-owned businesses that specialize in these wares.
These suppliers, often based in historic seaports and fish markets, have been serving the sushi industry for years, forming close relationships with local fishermen and Japanese food specialists. Through this extensive network of established relationships, top sushi making Tokyo chefs are able to access the freshest and highest-quality ingredients available.
Maintaining a strong network of trusted suppliers and regularly visiting fish markets to hand-pick their ingredients allows sushi chefs to ensure that each dish meets their high standards of quality and freshness.
