Green Beans in Egg Sauce

Ingredients

• 300 g young green beans
• butter
• salt and pepper
• 1 egg yolk
• 1 tsp flour
• 1/4 juice of lemon
• 1 ladle cold degreased broth
• 1 tsp baking soda (optional)

Instructions

1. Trim and blanch the green beans in lightly salted water; cut in three and flavor with butter, salt and pepper.
2. Beat egg yolk with flour and lemon juice; thin with cold degreased broth.
3. Cook the sauce, stirring, until it is a flowing cream, then pour over the beans.
4. Warm briefly so the sauce blends; serve as a side to boiled meat. A teaspoon of soda in the water keeps the beans green.
