We have glazed our BBQ with espresso balsamic before, but a recent foodie trend suggesting adding spices to coffee convinced us to change it up using our WTF#!? Spicy Jalapeno Olive Oil. Whisking our balsamic with olive oil to make an emulstion is a great way to create a BBQ glaze. Just use 1/2 balsamic and 1/2 olive oil and whisk until bended and creamy.
We used chicken thighs with the skin and fat trimmed. They were slow cooked on medium heat on the gril until almost done. For the last 10 minutes, we just brushed on the glaze, wait a bit and flip, brush on the glaze, wait a bit and flip ... we do 2-3 times until our chicken looks well covered with a crispy sweet coating.
You can make a little extra glaze to place on the table for extra dipping, especially for the center bites that the glaze does not reach.
