Lemon Caper Butter Sauce

This is one of the simplest yet greatest examples of a butter emulsion sauce. We don't brown the butter like in a French *beurre noisette*; instead, we just melt it with the flavors, preserving the fresh, milky character of the butter. Ideal if you don't have time for complex sauces but want to elevate a plain cut of meat.

Recipe FAQ

You overheated it. Butter melts above 86°F (30°C), but if it boils, the emulsion (water in fat) breaks. Just melt it, don't fry it!
