1) BBQ is not grilling.
2) BBQ isn't done in an oven.

It looks like the recipe says "broil in oven" OR "grill".

Grilling may be a form of barbecue.

It says BBQ not barbecue.

BBQ can be a sauce, as in this case...

The key word is "OR", I used 4 cloves of pressed garlic with the pressed garlic some red pepper flakes to counter the amount of sugar and as the maker says "Grilled" over medium hot coals (in my smoker with the charcoal pan at the bottom) for 30 minutes (15 minutes per side) with a 1 - cup of soaked hickory wood chips and it came out PERFECTO... Oven method as stated would have worked fine due to the HOT, HIGH Heat of the Broiler, gas or electric...

Love how everyone decides to quip over wording. It DOES say "broil OR grill". Stop trying to be a food authority - and just review the recipe.
