@psyk20,
The answer is "tea", t is the only letter on the word earth that has a taste, making it sweetest. Tea diluted with water gives us the anagram for Ta-weret(I take diluted to mean the a can overlap) the egyptian goddess, taweret with sugar added will give us an anagram of "sweet rugrat" and tea dried in sun gives us suntea an anagram for austen, Jane Austen being a famous author and reputedly a virgin. Tea is often seen in public places. Hope this helps.
