• 1/2 teaspoon cayenne pepper
• 1 1/2 tablespoons salt
• 1 egg yolk

Preparation

Step 1

In a six-quart soup kettle melt butter, add onions and reduce heat to very low, cooking until onions are melted down. Be careful not to brown in the first stage of cooking.

Add flour and cook 5 to 10 minutes more, stirring occasionally. Blend in stock, salt, and bring to a boil. Reduce heat and simmer about 15 minutes. Remove kettle from heat.

Beat together egg yolk and cream. Add a little of the soup and mix quickly, then add to soup kettle.

Serve in soup cups with toasted rounds of bread or croutons and sprinkle with grated Parmesan cheese, buttered breadcrumbs. Brown under broiler flame and serve.
