A little bit of soy, though I used tamari, and vegetable oil.
The gochujang comes in a red rectangular box and yes it's a paste. It's also quite spicy, but the finished dish wasn't spicy at all. The honey gets put on after it comes out of the oven. I don't know if it was the honey, the oil, or the heat of the oven that destroyed the spice factor but something did. A super easy meal. Put it together, stick it in the oven and you're done!

The recipe is for a whole chicken, but I used 3 skinless thighs and cut the marinade in half, baked them for a little over 20 minutes to a temp of 165.
