I just noticed on their website that Ontario Gas BBQ is carrying three items to amp up the authentic jerk flavours at home. They have pimento lump charcoal (mix of pimento and other wood), pimento wood chips and pimento leaves. Kinda pricey, but I'm going all in (well, at least the chips and the leaves). Wish they had pimento sticks. The supplier they use has those and I'd definitely buy those.
I was just in Jamaica and brought back some real special jerk sauce, so I'm excited to supplement it.
