A reader had enquired to Mrs Mills how to tell the ripeness of sweet corn as their wife insisted you could tell by gently feeling the swollen cob. Whereas the husband felt a firm grasp and a peel back from tip was a better guide. There was also a query that ripeness could be guaged by crushing the seed to see if it produced a milky fluid. Mrs Mills, that sage oh so wise, settled the debate by claiming they were both right! A translucent milky fluid should indeed come out if pressed hard; the cob is overripe if thick and white. If you have pulled back the husk to soon an elastic band round the husk will keep it going til it's, er, ready.
I decided to see what others in the know suggested.
Jane Grigson offers further advice on how to prepare said cob by standing it upright, held at a slight angle and to scrape done as hard as you can. You should continue to do this more vigorously to get the last bits ( kernels I believe) and juice. Apparently it can be done quite rapidly too.
The BBC Gardening guide tells you that the corn is pollinated by the make flowers shedding onto the females tassels.Ripeness is indeed down to milky juice.
Any body else care to comment?
