Mary invites great pal, presenter and comedian Sue Perkins to spend the day with her. Although a talented cook, Sue always over-complicates when hosting a crowd and never follows a recipe, which often leads to disasters in the kitchen - she needs Mary's help! Fortunately, Mary has an array of foolproof tips and fantastic new ideas to inspire Sue, with recipes including falafel with whipped feta, a goat's cheese, asparagus and fig bruschetta, some aromatic chimichurri pork with chargrilled hispi cabbage, and a rhubarb plate pie. After reminiscing about their time working together, the two head to Mary's garden, where she shares tips on planting supermarket herbs. Keen to tap into more of Mary's expertise, Sue suggests a game of tennis and is surprised by Mary's unique style of coaching.
