This week is all about umami flavours or savouriness which is one of the five basic tastes alongside bitter, sour, sweet and salty. Foods that have a strong umami flavour include meats, shellfish, anchovies, soy sauce, marmite and strong cheese. AJ and Susie talk to Adam Sopher who makes popcorn with interesting umami flavour combinations including Irish stout and cheese on toast. What?! Harry Turpin is also in the studio with his umami Crunchits.
