Brassicas are an important agricultural crop and include such varieties of vegetable as broccoli, cauliflower, cabbage, kale and brussel sprouts. These vegetables are staples on our supermarket shelves and are all highly regarded for their nutritional profile. Over the last few decades, with the proliferation of global food trade and increased personal travel, consumers have been introduced to other members of the Brassica family, which include horseradish, rocket and wasabi. As international tastes have developed, so has the demand for these delicious ‘mustards’.
