6 Pre-sliced Brioche Burger Buns Golden like a Parisian sunset, soft and curvaceous. Our brioche burger buns are made for you to take your time. Add some French mustard to yours to take your loved ones' taste buds on a trip to Paris. At St Pierre, we bake our soft, slightly sweet, buttery tasting light brioche using six centuries of French know-how (or savoir-faire) and a belief that every day should be "magnifique"! Our brioche is a mouth-watering treat that will raise all your favourite dishes to new heights.
