BrusselKale is the latest superfood to hit the market.
The hybrid is not the result of genetic modification, but of cross pollination between the two vegetables. In fact, seed company 'Tozer Seeds' has been working on this combination for the past 15 years. The company describes the taste as a "fusion of sweet and nutty." This description sounds rather curious, as I recall neither of these vegetables having a "sweet" taste (although maybe I'm not the most reliable source -- I haven't eaten anything green in years).
I'm sure the kale army will be all over this superfood. Because foods can never be too super, can they? If you have yet to accept kale as your lord and savior, perhaps the brusselkale will do the trick.
