Sweet Tropical Rub A sweet rub with a little heat, Pineapple Head is a perfect match for grilling pineapple. Well, that’s what we designed it for anyway. Then our customers got ahold of some and found that it’s also excellent on any grilled fruit, in a pie filling, or on a fruit salad. Customers have reported success using Pineapple Head on sweet potatoes, squash, pork chops, seafood and chicken. It’s very low on salt, so don’t hesitate to add salt if used on meat.
