No. One of the great attributes of this recipe is its versatility. Just use the process to suit your time requirements. If you are only able to leave your salted chicken in the fridge for an hour or so it will still improve the flavour and texture of the chicken. But it is a revelation if you leave it for 24 hours. Do not be concerned that covering the chicken in salt will make it dry. Although the salt draws some moisture out of the meat, this is eventually re-absorbed along with the salt and spices. This means the chicken will be moist and beautifully seasoned throughout.
