My interest in them is two-fold: they can be harvested in the winter, and they are spectacular in bloom. I haven't had the farting problem yet (although you are not the first to ask about this), and have mostly used them cut very small in rice pilaf, or in dog food. I used to ferment them, and had no gastro problems then - they were quite good! I need to get back into fermentation, everything tastes good fermented, especially rutabagas. My kids even liked those.
