Why We Blitz the Bread
Using a blender rather than a food processor yields a smooth dressing and whips in air for a light texture.

Ingredients
Preparation
Step 1
Preheat oven to 425°. Toss half of bread with 1 tablespoon oil on a rimmed baking sheet; season with salt and pepper. Bake, tossing once, until golden brown, 8-10 minutes.
Step 2
Pulse garlic, vinegar, mustard, sugar, remaining bread, and 2 tablespoons water in a blender to combine; let sit 5 minutes to soften bread. With motor running, gradually add remaining 1/3 cup oil; blend until smooth (bread will blend into dressing, thickening and flavoring it, while retaining some texture), about 2 minutes; season with salt and pepper.
Step 3
Toss radicchio, scallions, croutons, and dressing in a large bowl; season with salt and pepper.
