NYT Connections today: Hints and answers for September 30

Connections, a popular word game by Wyna Liu, is available on browsers and mobile devices. Players must group 16 words into four sets based on shared characteristics, ranging from book titles to country names. Each correct set removes words from the board, while incorrect guesses count as mistakes. The difficulty of each group is indicated by color. Today's clues include cooking with water, common perfume ingredients, characters with pet dogs, and capital city homophones.
