Taste, Flavor
noun
The kanji and the word are exactly the same. That means they share meanings as well.
あじ
Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word: You may have the ability to taste things now, but just wait until you get up there in age (あじ). You'll find that the tastes and flavors you once liked will become bland, and you'll need a lot of Sriracha to make things taste better.
この味、お口に合うといいんですが。

ここのラーメンの味、昔からずーっと一緒なんだよ。

このスープの隠し味はフグの骨なんです。
The secret taste of this soup is puffer fish bones.
