Even though many people refer to Pesto as a paste/sauce made primarily from basil leaves and pine nuts, the term “pesto” can actually be used to describe any other similar types of paste. I like to experiment with different herbs and nuts in such pestos (as you can see in THIS post or THIS one).
This time, I’ve chosen tarragon leaves and cashews as the main ingredients for the tasty paste. Tarragon is a wonderful herb, which is used extensively in classical French cuisine, as well as in the Caucasus region countries. Its’ wonderful aroma and mild anise flavor mix well with the creamy texture and sweetish flavor of the cashews. With the addition of garlic, Parmesan cheese and olive oil, it turns into a unique, highly aromatic and tasty pesto, that can be used in versatile ways.
One of the tastiest and simple ways to use it , is to pair it with grilled meat. Here I’ve paired it with Flat Iron steak, which is a highly flavorful cut, that requires very short roasting time. So, once you have the pesto ready, it takes only minutes to prepare this tasty and impressive dish. Try it and enjoy.
* Since this pesto can be used in various ways, from sandwiches to pasta, soups and more, it’s worth it to prepare a fairly large amount of it. It can keep, in an airtight container in the fridge, for up to ten days.
* Flat Iron steak is at its best when cooked to medium-rare degree, so do your best not to overcook it. Make sure it is at room temperature before roasting.

1. In a large food processor bowl, fitted with the metal blade, place the cashews, garlic, cheese, salt and pepper. Process briefly and add the tarragon leaves. Process briefly again, scraping the sides of the bowl once, and add the oil. Process again, scraping the sides a few times, to the consistency you prefer. Taste and adjust seasonings if needed.
