I did it: Two baked potatoes, cooked unwrapped over direct heat in my kamado until done. That is, an easy give when squeezed with tongs and >205º. Mixed 1t of granulated garlic in 1 FL OZ of butter and
poured it into my injector. Next, injected the potatoes. The mixture leaked out of the thermometer probe and injector holes- the same thing that happened to Kristin + Bentley. The taste was definitely faint
but noticeable. A more heavy butter/garlic taste would be made by cutting the potato open and adding butter and garlic..The next time I won't temp probe and will carefully insert the needle by using one
hole at the top to carefully distribute the mixture...The leaked mixture smoked a lot when it hit the coals and didn't generate any off taste to the pork-chops that were cooked later at a much higher
temperature.
