I’m cooking on a uds that I put together. I feel like I can’t taste the different rubs I try at all. I was putting chunks of wood on but decided to stop thinking I might be putting too much and covering up the rubs but they seem to taste the same. Any idea why this is or what I am doing wrong. I tried sprinkling a little of the rub on again after I unwrapped them last time and could taste the rub then.
