French Dressing and Salad

 The French dressing I know today is red in color and none of these ingredients are red so this must be pretty old! Looking at the process it sounds like this might be a fermented version.

Ingredients

 1/4 Tablespoon salt (this translates today to 3/4 teaspoon)

1/4 teaspoon black pepper

1 Tablespoon mild mustard

1 cup good vinegar

cream

Process

 "Mix salt, mustard, and pepper together and add vinegar. Put it in a bottle or jar and let stand for a week, shaking every day. To mix dressing use a Tablespoon of vinegar with 4 to 6 Tablespoons cream according to taste. Rub salad bowl with garlic. Toss in well dried greens in the dressing so that every leaf is coated. If necessary, add more dressing but never start with too much. Let stand 5 minutes before serving. For a change, add either crushed soft-boiled eggs, a pinch of curry, a chopped deviled egg, some chopped herbs, or a minced shallot. "
