For the chive sauce, pour the milk over the white bread and let it soak. Mix the soaked white bread, yolks, salt, sugar, vinegar and half of the chives in a blender until creamy.
Continue blending and add the oil, first drop by drop, then in a thin stream. Stir in the remaining chives and season with salt. The chive sauce goes well with boiled beef or roasted or grilled meat.
