Why It Works
- Using an immersion blender makes it totally easy to form what can otherwise be a difficult sauce.
- A basic tomato purée made from fresh tomatoes adds a bright, sweet flavor.
Most of us know that Béarnaise is a derivative sauce based on Hollandaise, but how many of us know other children of that classic French mother sauce? Here's one to add to your stable: Choron sauce, made by blending tomato purée with Béarnaise. It's delicious on steak, chicken, eggs, vegetables, and more. If serving with steak, as shown in the photo here, try any of our basic steak recipes, including grilled steak, pan-seared steak, and sous vide steak.
As soon as you finish making the Béarnaise, add the tomato coulis and blend with an immersion blender until completely incorporated. Taste sauce; if the added sweetness of the tomato requires it, add more vinegar to taste until sauce is well balanced. (It should be sweet, with a subtle but noticeable tartness.) Keep warm until ready to serve.

If your tomato coulis (i.e., the purée) is a little bit thin, reduce it by gently simmering it in a nonstick skillet until it forms a slightly thicker purée; use a full 1/4 cup of that reduced purée. You can also substitute 2 tablespoons tomato paste for the 1/4 cup tomato coulis.
