"It makes good meat taste like ham."
You're doing it wrong. It shouldn't taste any different.
"BTW, that 155 better be Celsius. It seems high, but any other 155 (K, F, or R) would be horrid."
155F for breast meat is near perfect. Cooked, but still juicy. Some people are freaked out by any hint of pink on the bones. I feel sad for them, but they could cook to 165 or 170 and probably it would not be too overcooked. 155 C would be dried out and inedible.
