Brussel Sprouts are like small cabbages that grow on a stalk. They are high in vitamin A, C, K and fibre more nutritional information here. They have the flavour of broccoli and cabbage combined.
We like to give them to you on the stalk so you can see how they grow - like small trees. You may not have prepared this before so check out this video on how to do it. Just break or cut off the little sprouts and prepare as you wish - steam, broil, braise, bake, stir-fry. Careful not to overcook, they are sort of like broccoli in that they turn nice bright green when cooked properly, then turn brown and mushy when over cooked. This page goes over some different cooking methods.
