I just wondered whether cooking method (e.g. boiling vs steaming vs roasting) affects the fart factor? Can't believe I never considered this before. There may be an optimum way of getting the most efficient sprout-to-gas ratio that could be measured as cubic litres of fart per kilogram of vegetable. I think Mrs tonrob and I need to conduct some sot of scientific experiment this Christmas...

Thanks MrEmjoy!

tonrob - if you can come up with a reliable and repeatable way of generating large volumes of precisely timed farts, that might be very useful, for airports doing enhanced patdowns and suchlike.

The most effective way of getting the most STG ratio is to boil them as much as possible.

Roasting will have the least amount of STG ratio.

Steaming will eventually get them there as essentially its the same process as boiling them but boiling them will get you the most STG.

I think the brighter green they are the the more STG you will get.

And if you boil them you can use the water for gravy - double the fun.

It was this recipe, thanks for finding it for me!! They were YUMMY!!!!
