What should I look for when buying a bread maker? Delay timers are handy too, should you want to set your bread maker to start kneading your pre-prepared ingredients while you sleep or are on your way home. Similarly, a keep warm function will keep your bread warm for up to an hour after baking finishes. How we testWe put a range of bread makers to the test, firstly by baking a white loaf using both our own recipe and any supplied by the manufacturer. We repeated this trial for wholemeal bread and tried out the quick bake and gluten-free settings too.
