- 1 1/2 teaspoons Dijon-style mustard
- 1/2 teaspoon sugar
- 2 tablespoons minced shallot
- 2 tablespoons red-wine vinegar
- 1/4 cup walnut oil
- 1/4 cup vegetable oil
- 8 green Belgian endives, trimmed
- 8 red endives, trimmed
- 1 cup walnut pieces
- In a small bowl whisk together the mustard, the sugar, the shallot, the vinegar, and salt to taste, add the oils in a stream, whisking, and whisk the dressing until it is emulsified. Line a large salad bowl with some of the endive leaves, cut the remaining endives crosswise into 1/2-inch slices, and add them to the bowl with the walnuts. Just before serving, drizzle the salad with the dressing and toss it to combine it well.
