that will actually make your house smell fragrant and fishy...
get a dutch oven half full of water to a roiling boil
add a teaspoon of peppercorns
some sprigs of tarragon
some sprigs of thyme
several bay leaves
two sliced lemons
2 tablespoons salt
1/2 tspn cayenne
boil all of that for five minutes, turn off the heat.
add a pound of shrimp [for two] stir, then let stand in the water covered for 10 minutes.
you could, of course, add your malted beverage of choice to the water...
