It's Better with Butter Sauces
Butter sauces are those which use butter as their foundation and primary flavor. Some are made from butter which has been melted and then finished with other ingredients, such as a brown butter-caper sauce. Others are made by slowly adding melted butter to an egg base such as a hollandaise or bearnaise sauce, and some are made by incorporating whole, soft butter into a reduction such as with a beurre blanc. There are also compound butters which are made by adding different ingredients such as herbs or sun dried tomatoes to softened butter and then letting it harden back into its original state. These compound butters are sliced and placed upon something hot, such as a just-cooked steak, and allowed to melt onto the food creating a simple sauce.
