Classic Hollandaise Sauce

I'm trying to serve more sauces as they can truly enhance a meal.   This sauce--classic hollandaise--is one that is making it to our table more and more frequently.   Rich with butter and egg yolks, the sauce is dense with wholesome fats and micronutrients.   Make sure to use quality ingredients like eggs from pastured chickens and butter from grass-fed cows as these foods are the more nutrient-dense than their conventional counterparts.   We often serve it over eggs, salmon and vegetables.
