Rabbi Blumenkrantz zt”l in his Pesach sefer from several years back indicated a problem with corn on the cob. This is not new, but maybe wasn’t discussed so much in the past. And over three years ago, I saw
(I know. Ashkenazim don’t eat corn on Pesach – kitniyos. Rabbi Blumenkrantz’s sefer has a section on checking fruits and veggies; the section isn’t limited to Pesach.)
The following information is found on the Union of Orthodox Synagogues – South Africa. I know many readers here are not from South Africa, but it’s still of interest:
CORN (MIELIES)
In this country, both white and yellow mielies on the cob have often been found to be infested. It is impossible to get rid of the infestation whilst still on the cob, as the thrip hides between the kernels.
In order to eat mielies:
Equipment required: detergent, bowl, sieve / colander
1. Cut all the kernels off the cob,
2. Soak them for 3 minutes in very soapy water, and
3. Thoroughly rinse them through a sieve or colander.
4. Cook and enjoy!
Alternatively:
Equipment required: sieve / colander
1. Cook the corn whilst still on the cob
2. Cut all the kernels off the cob,
3. Thoroughly rinse them through a sieve or colander.
4. Discard the water that the corn was cooked in.
Frozen or Tinned Corn may be used as these have been extremely thoroughly rinsed in the factory.
