* If you don’t have chipotle powder, you can use all red pepper flakes (1 teaspoon or to taste). The chipotle powder gives it a bit of smoky flavor.
* If you’re using dried pasta, add the pasta to the pot of boiling water just as you add the clams to the pan. They take about the same time to cook. If you’re using fresh pasta, add to water a few minutes before the clams are done.
