Traditional Portuguese Piri Piri Sauce for Chicken

I love churrasqueira chicken and have been looking for a recipe to make it myself. I found this on Breakfast Television Toronto's web site. They got the recipe from Roasty Chicken Churrasqueira which is in the town of Maple just north of Toronto. A friend told me that she's used this sauce for fish and shrimp, too. I've tried it on shrimp and it's wonderful. Simply marinate the shrimp for an hour and then drain the shrimp, discard the sauce and grill the shrimp on the barbie.
