A soup course may be old-school, but it never fails to delight, putting any special-occasion meal right over the top. The smooth, sophisticated pea and parsley soup is an homage to the season. It gets body from creme fraiche and a salty snap from orbs of golden caviar.
Mugwort (Artemisia vulgaris) is one of about 300 species in the Artemisia genus. It's what you want for this soup; the others may be too bitter. Watercress will also work; although the soup won't taste the same, it will still be delicious.
