You've only got $5 to buy ingredients to make a meal for two. What do you buy and what do you make? Go!
Well, I'm going to change that to £5 (given the exchange rate and the cost of things over here compared to the states)
Some clams, some mussels, a shallot , spring onion (scallions you call it), linguine and cream.
1) I'd steam open the clams and mussels together. Once opened, keep the liquor and shell most of them keeping a few for garnish.
2) Cook the pasta in boiling, salted water
3) Add a knob of butter to the liquor from cooking the shellfish, cream, a finely chopped shallot and some chopped parsley then the shell fish (minus the ones still in the shells)
4) Drain the pasta (not completely) and toss it in to the pot with the liquor above.
5) Serve in two bowls, dress the plates with the left over shellfish in the shells and a few finely chopped pieces of spring onion and more parsley.
et viola!
