From gourmet burgers to high-end patisserie, London is awash with delicious fast food. Rachel samples a selection of the capital’s exciting fast food, and demonstrates how such treats can be effortless to cook at home. She meets Lisa, whose popular hot Taiwanese sandwiches bring back memories of Rachel’s own childhood. And in south London, Rachel gets into the kitchen with Trinidadian cook Brian to create some intense flavours for his Caribbean Jerk Chicken. Back in her kitchen, Rachel creates a twist on an icon of fast food and shows us how to create breakfast, lunch and dinner from one quick bread recipe.
