For the Peasant Pasta any of the Tuna on the first 2 rows is a good choice! More flavor, better ingredients than your usual choices. If you have never heard of or tried Ventresca or Tuna Belly it is a true delicacy and these are the best examples from the leading makers in Spain and Protugal.

These are all likely ingredient options you will find in the store that sent you to this website. The squid ink linguine is a great option for this dish although the White Linguine from Marella or Gentile are both excellent choices also.

The IContadini Capers are larger in comparison to what you normally see in stores. I chop them up when I use them.
