First off, this site is amazing...
I just got my first smoker last week and have jumped headfirst into it. (Figuratively... not literally!)
Having invited friends over this past weekend for my first smoked dinner, our kids nut allergies came up. I started thinking about almond wood and whether that could cause problems.
My son's peanut/tree nut allergy is pretty mild (his face breaks out in mild hives), but by friends son is severe (I was with them when he was rushed to the ER in shock).
Having gathered enough info, I won't risk using almond wood, but do find this interesting.
