This mashed potato recipe, courtesy of Colombe St-Pierre, chef and co-owner of Chez Saint-Pierre and Cantine Côtière, stands out for its silky texture and delicate flavour. Cook the potatoes with lemon wedges and a sprig of thyme, and then mash them into a purée with a reduced cream that gives them an irresistible velvety texture. Round it all out with a parsley-flavoured oil that provides freshness and a herbal note. It's the ultimate side dish for lemon chicken.
