The taste of salt is a salty taste (it's also when something tastes salty).
しおあじ, えんみ, しおみ
The readings are the kun'yomi vocab readings. So, take the readings of 塩 (you learned the reading with the kanji) and 味 and you have yourself しおあじ. If you happen to be a cooking show fan, you might also hear the on'yomi reading of this word - えんみ. This word can also be read as しおみ, which has more or less the same meaning as the primary reading you learned.
