We had some leftover pre-shucked oysters and used them to make this Bon Appetit recipe. The recipe here originally used an entire 16-oz jar of pre-shucked oysters, but we halved it; serves two.

Ingredients
1/2 tablespoon butter
1/2 tablespoon all purpose flour
1/2 cup whipping cream

2 slices thick bacon (preferably applewood-smoked), chopped
1 tablespoons grated Pecorino Romano cheese

2 cups thinly sliced leeks (white and pale green parts only; from 2 large leeks)
