I made this last week and forgot to post about them.
I had been to market a bought a 'stick' of sprouts ... they were very fresh. By the time I had snapped them off the stick I had about 250 gm - actually a bit more than that, I think. Anyway, I cooked them up but stupidly used the given quantities for the sauce so there wasn't as much of that as I would have hoped, I should have made a larger quantity.
Unfortunately the dish I cooked them in was too high sided so they didn't get crunchy either, which was a shame. But, having said all of that, I thought they were very tasty and I will definitely make them again, but will adjust sauce quantity if necessary and roast them in a shallower dish (all my shallow dishes were being used for other things at that time so I had no choice ... bad planning on my part!).
