If you are short on time, it is not necessary to form a log with the butter. Just garnish the chicken with dabs of the butter.
Sorrel is an herb with broad leaves with a spicy, tangy, and slightly lemony taste that goes well with butter, fish, chicken, and vegetables. It can also be eaten raw. Cooked, you prepare it like spinach. It is readily available in the fruit and vegetable aisle in supermarkets, along with bagged, ready-to-use fresh herbs.
