Tarragon Mustard Salmon Steaks

4 Salmon steaks
Fresh lemon juice
2-3 Tablespoons olive oil
Sauce:
1 Tablespoon Dijon mustard
1 Teaspoon sugar
1 Tablespoon white wine vinegar
2 Tablespoons finely chopped fresh parsley
1 Tablespoon chopped fresh tarragon or 1 teaspoon dried
1/4 Cup olive oil

For sauce: In a small bowl, combine mustard, sugar, vinegar, parsley and tarragon. Blend well. Slowly add olive oil, blending well. Set aside.
Brush salmon with lemon juice and olive oil. Place under a preheated broiler for about 5 minutes. Turn and broil for 5 minutes more or until translucent. Spoon sauce over steaks and serve immediately.
Note: This piquant sauce is also wonderful served with tuna. It may be made ahead of time and refrigerated before using.
