With a large 2.5 litre bain-marie bowl for scrumptious soups, desserts and sauces, this steamer accommodates a range of different dishes, designed with cook's-safe vent holes, to stop you burning your fingers. The unique Flavour Booster adds a delicious aroma of herbs and spices, bringing even more taste to steaming. Simply pop your favourite herbs and spices into the booster, and let steam do the rest. The heat from the steam releases delicate aromas from the herbs and spices, which thoroughly infuse the food with their mouth-watering flavours. The steaming tiers are numbered -- you can find the number on each tray handle. The bottom steaming tier is one, the middle is two and the top three. Use one, two or three tiers while steaming and make sure that you add the tiers with higher numbers on top of tier one. After use, you can stack the tiers and use less space for storing.
