Friday night is pasta with vongole since forever, and we have come up with lots of variations as the years have gone by. This combination, with chewy pieces of pancetta and some greens, might be the family favorite, but by no means is this canon. Throw some cherry tomatoes in with the garlic and omit the greens, or use both. Leave out the pork product if you want. You can double or triple the recipe as long as you divide the pasta between two big pots. The only real rule is to make sure the table is set and everyone is within earshot when the clams start to open; hot pasta waits for no one.
Ask the fishmonger to cut the grouper into 1-inch cubes for you and remove the shells and veins from the shrimp. You’ll want to purchase clams that are the same size so that they cook evenly. Adding the clams to the stock while it comes to a boil helps speed up the process.
