Fermented Seven Spice Mango Onigiri Recipe

Japanese seven spice, also referred to as shichimi togarashi, most commonly contains a blend of red pepper, Sichuan pepper, ginger, white and black sesame seeds, orange peel and nori flakes. It contributes a multi-dimensional savory flavor alongside a gentle heat, and is commonly used to adorn ramen, udon noodles, tempura and edamame.

Since mango, chile and lime are such a well-established combination, the idea to lacto-ferment mango pieces with a citrus, chile-based spice blend came to fruition when developing this ferment. The next step was to utilize it to fill the interior of a popular Japanese rice dish, onigiri.

Onigiri is a triangular or cylindrical piece of white rice and is commonly filled with fish or umeboshi (fermented plum) paste. The fermented mango contributes sweet, salty and sea notes, culminating in a flavor-filled bite.

What鈥檚 Good to Know with Chef Olivia:

  • Using the fermented mango brine to season the sushi rice is not only resourceful but also imparts a great deal of flavor.
  • This ferment would taste delicious mixed with some mayo and used as a dipping sauce for French fries.
  • Serve your batch of fermented mango over coconut sticky rice for a savory version of the beloved dessert favorite.
  • When preparing your ferment, try to source mangoes that are not rock hard but also not too ripe. This will help them keep their shape when fermented.
  • Try adding your mango ferment to burritos, breakfast tacos or spicy tempura sushi rolls.
