This creamy sauce can be made in a jiffy, and stores well in the refrigerator for several days. It doesn't get solidified in the fridge, and can be heated quickly in the microwave. Do not prepare or store in metal except stainless steel or un-chipped enamel! Use over asparagus or other veggies, or cold over salads. It's a healthier alternative to Hollandaise sauce, and can be used in place of it.
1/3 Cup unsalted
Place broth in a pan and bring to a boil. While waiting, beat egg until foamy. Add lemon juice and cornstarch (and salt if needed) and beat again until well combined. Slowly add about 2 T. of hot broth, continuing to beat. Add tempered egg mixture to the boiling broth, stirring constantly. As soon as it thickens, remove from heat and add olive oil, and black pepper if desired.
Use over veggies,
pasta or eggs as you would Hollandaise sauce. Garnish if you wish with
chopped parsley or other herbs. Store in a non-reactive covered
container in the refrigerator for a few days if you wish. It can
be used chilled over salad, or heated briefly in the microwave.
