Periwinkles for Dinner?

I bet you didn't know periwinkles are edible! They are a bit of work, since each provides only a tiney morsel, but have a delicate flavor somewhat like mussels. It makes for a fun day, collecting periwinkles to bring home for dinner.

Here's how to prepare them, from cooks.com:

Steamed Periwinkles
1/2 c. salted water
1/4 tsp. thyme
1 clove garlic, mashed
1/2 c. beef bouillon or dry white wine
4 dozen well-scrubbed periwinkles
4 tbsp. butter 

Rinse the periwinkles thoroughly; put all ingredients in pot and bring to a boil; add periwinkles and steam until they can be easily extracted from the shell, about 4 minutes. Serve with melted butter.
