Put dried or fresh herbs or spices in the flavour booster in the drip tray. Thyme, coriander, basil, dill, curry powder and tarragon are some of the exciting herbs and spices that you can use. You can combine them with garlic, caraway or horseradish to enhance flavour without adding salt. We advise you to use 1/2 to 3 tsp. of dried herbs or spices. Use more if you use fresh herbs or spices.
