They may look incredibly similar, but there is a difference between pepperoncini and banana peppers. Pepperoncini are a mild pepper native to Italy, which have been pickled in a tangy brine. The peppers are only mildly spicy, and are popular in both Italy and Greece as they're featured in many Mediterranean dishes. Of all of our creative ways to use leftover pepperoncini juice, however, making a tangy garlic butter might just be the best of them.
In our recipe, we start with the notion that a perfect picanha steak needs nothing more than a simple salt and pepper seasoning - but we take it to the next level by adding a dab of garlic butter towards the end of cooking. This gives the steak more flavor, locks in its moisture, and gives it a bit of a zesty kick.
