Yogurt Hollandaise Sauce - cooking recipe

Ingredients

1 cup low-fat plain yogurt, plain
2 teaspoons lemon juice
3 egg yolks
1/2 teaspoon salt
1/2 teaspoon Dijon mustard
1 pinch fresh ground pepper
optional 1 tbsp fresh dill or parsley

Preparation

Use double boiler or like me - place a strainer/sieve over a sauce pan of water and place a bowl in the sieve.
Beat yogurt, lemon juice, egg yolks well
Heat over simmering water, stirring frequently, until sauce has thickened, approx 15 min (sauce will become thinner after about 10 min and then thicken again).
Remove from heat and stir in salt, mustard, pepper and dill/parsley (if using).
