Another artisan ice cream maker joins the Bermondsey Trail. The Ice Cream Union is now open Saturdays under the railway arches at 4 Voyager Business Park (just 3 doors up from Kappacasein). One of their signature flavours is Dulce de Leche, based on the sweet, sticky Argentine caramel. Maybe I need to do a taste-off between this and Real France's Salted Caramel. Union also deliver - see the website for more info.
