21 day steep:
The pb&j part is very authentic, but the milkshake needs help. It's just cream right now. Maybe needs more VIC, or some malt, or a tiny hint of koolada, or all of those. I haven't used koolada in anything yet, so im not sure about it. Overall, it's quitevtasty, no off notes, real tasting pb&j, but needs time or tweaking.
