Chicken, they taste like chicken.
The big old boars have tough meat and we drive over the back straps with a tractor about five times. Then we marinade it in lemon juice for a couple days, put it on the grid and use it as staff rations the following day.
I usually have someone shoot us a young porker that goes on a spit braai. Now that's some good eating right there but I cannot pinpoint the taste to pork alone. Somewhere between pork, chicken and beef. Really good though.
