If I put a dry-rub on a chicken and then baste it (once it's started browning) while oven-roasting, will I wash all the rub off?
No -- the rub should mostly stay on and if any washes off, it'll only flavor the basting juices.
Ah, thank you!
You can also put some of the dry rub under the skin and it will definitely flavor the chicken well. Just shove your fingers between the skin and the breast and you can wiggle your way down to massage the rub in.
