If the shallots have been treated prior to selling at the supermarket so they wouldn't sprout, then that means they are dead food. Probably not very good for you; the same treatment that killed the bulb could have a bad effect on us. Or at the very least, destroy vitamins and enzymes. I am increasingly growing as much as possible of my own living food--shallots, garlic, onions, potatoes etc.-- without sprout-retardant chemicals.
I'm trying to 'grow my own' as well, but starting off with green leafy things to get the 'biggest bang' for the effort. Have you seen how much spray is on supermarket silverbeet - awful! Do onions take much room?
