Step 1

Pour the lemon juice and broth/stock into a large saucepan or skillet/pan. Then cook on a medium high heat until reduced by about half.

Step 2

Now turn the heat down to medium low. Add the cold pieces of butter one at a time, swirling around until fully incorporated into the sauce.

Step 3

Stir in the fresh herbs and salt and pepper to taste. Serve spooned over chicken, steak or seafood, stirred through pasta with parmesan, or as a dip.
