I've never used corn flakes (or corn for that matter) but a common kids experiment is to extract the iron filings out of corn flakes (which are fortified with iron). Not sure if iron filings would do anything negative to a beer, just putting it out there.
No, probably best to gelatinise raw corn wombil, so boil it for a while first in a thin porridge. As per Bribie, use some reserved strike water or perhaps do a cereal mash if you feel energetic.
I've used cornflakes, a kilo to be exact (2 packets of ALDI) but due to the sodium content you could pick the salt, gave rather a dull flavour.
ALDI is a good source of adjuncts :lol:
A planned ALDI Ale, never got round to it but all got eaten eventually.
Corn flakes are reasonably common in a beer where it is only the steam that is of interest. Cracked corn needs 2 hours cooking to gelatinise properly and it's still a ****. :angry:
