Professional baker Lani Halliday and home cook Emily are swapping materials and hoping for the best! We set our resident ketchup queen Emily up with $118 worth of the finest ingredients you could ask for in a brownie, along with chef Lani’s recipe. To offer some on-the-go expertise, food scientist Rose dialed in for a tutorial teleconference and pep talk. Over in Lani’s kitchen, $14 worth of ingredients were being stretched to their limit in a quest to improvise her way up to gourmet.
