I'm already beyond my expert knowledge, but that has never stopped me before ---
blanching corn before freezing it is meant stop enzymes in the corn from whittling
away at the sugars (some biologist will correct me on this, I'm sure). These are
the same factors that make wonder fresh corn not so good if it is forgotten and
cooked a week later.
Published formulas for preserving (including freezing) tend to risk over cooking,
if that will increase the chances that the product can be pulled out of the freezer,
even 10 months later, and look good, and taste OK.
Corn-on-the-cob is an even more extreme example, since it needs to be in the
boiling water long enough for the cob to be heated through, all so it can be brought
out in February, and still look beautiful.
If someone did a test and froze some corn without any boiling , and some done
3 minutes, and some done 6 minutes (and some done 9 minutes ...) I don't really
know what the differences would be.
I know this does not really answer the question ..., but it's the best I've got.
(I know I should quit while I'm ahead, but ... (more muddying of waters) ...
Most cooks are not like me, in that they don't cook something, plate it up,
and hurry to dining room shouting "Eat this before it's ruined!" If I cook
corn, and it is not consumed for another 10 minutes, residual heat continues
cooking ... I knew shouldn't have started this ...
