Why mineral-rich soaking bath salts make a good gift

A jar of salts pairs well with a candle or towel for a spa-style basket.
Scented and unscented blends are both easy to find, so preferences are simple to match.
Salts are shelf-stable, so they can wait in the cupboard until a free evening.

What to look for

Check the salt type listed on the label, such as Epsom, sea or pink salt.
Look at the container size and whether it reseals well to keep out moisture.
Note whether essential oils or dried flowers are mixed in, and if a scoop is included.
