A Little Bit About Japanese Yuzu

Yuzu is an aromatic citrus fruit that has its roots from central China. It was later introduced to Japan and Korea during the reign of Tang dynasty.

Yuzu is green when unripe but it will have a yellow color once it is ripe. The skin is textured and uneven. Yuzu also has big seeds, thick skin, and a fragrant smell. In size, yuzu is slightly bigger than mandarin orange but smaller than a grapefruit. Green yuzu can be harvested around July to October, while ripe yellow yuzu can be harvested around October to December.

  

Like lemon, yuzu has a very citrusy sour taste. But yuzu tastes slightly different since it has a tart taste resembling more of a grapefruit than orange or lemon. The aroma of yuzu is also very prominent. Making it great for seasoning food. In Japan, you can easily find condiments like yuzu sauce, yuzu shichimi, yuzu salt, yuzu miso, and multiple others.

  

Right now there are multiple countries outside Japan that have successfully cultivated yuzu in their regions such as Australia and US. You can even buy yuzu plants in UK that have been grafted to a rootstock in order to be more suitable for European climates.

How does Yuzu Kosho taste like?

A little yuzu kosho goes a long way. The citrusy fresh flavour complements the modest bitterness from the yuzu peel. This condiment pack a punch with the sophisticated combination of acidity, savouriness and spice.

  

The tangy and fresh flavour profile of yuzu kosho goes well with multiple types of protein. Yuzu kosho weaves beautifully into the layers of meat, adding a little twist of flavour and cutting through the unabating tang of meat. There is also no need to be generous with salt as yuzu kosho itself is already salty. You can rely on Yuzu kosho for the burst of umami.

Red Yuzu Kosho vs. Green Yuzu Kosho

red vs green yuzukosho
  

Green Yuzu Kosho uses unripe yuzu (green in color) and green chilli as the main ingredients. Red Yuzu Kosho uses ripe yellow yuzu and red chilli as the main ingredients. Yuzu Kosho is generally used not only as a condiment, but also to add an accent to enhance a range of dishes.

  

Taste wise, green Yuzu Kosho is fresher and sharper whereas red Yuzu Kosho has a mature fragrance and tartness due to the use of ripe yuzu and a more pronounced umami flavour of red chillies. Needless to say, it’s a necessary addition to your repertoire!

  

The difference in Green Yuzu Kosho and Red Yuzu Kosho aren’t tremendous, but it can certainly play distinct roles. Green Yuzu Kosho can be used as a wasabi substitute. For instance, pair it with sashimi, yakitori, somen soup, carpaccio, miso soup, peperoncino, or with butter to make toast or rusks. Additionally, Green Yuzu Kosho goes very well with soy sauce and olive oil. Red Yuzu Kosho on the other hand, is a great mustard substitute. Fundamentally, it uses ripe ingredients and is recommended for hot dishes. Therefore, it goes well with natto, oden, udon, motsunabe, pork soup, gyoza sauce, ajillo and more.

Ingredients
  

  • 80 gr Green chili peppers can be substituted with serrano pepper or habanero
  • 80 gr Green Yuzu zest (unripe) or other citrus zest
  • 16 gr Salt

Instructions
