Flaked maize vs quick corn grits

Anyone have input on using quick corn grits  as a substitute for flaked maize in a mash?

Unlike flaked maize, quick corn grits are not fully pre-gelatinized; therefore, they have to be heated and gelatinized before being added to the mash.

Thanks. I don’t have a LHBS where I live and finding a grocery store ingredient substitute is my only option when I don’t want to order online.

The large industrial brewers use straight corn grits and a cereal cooker.

I had really great luck using corn grits in a Mexican-style lager; I had to do a cereal mash (which was a bit of work, but not that hard in terms of process)…

So yes, corn grits are fine, if you are willing and able to do a cereal mash.
