It sounds like you are insinuating that the CRC is not a competent Rabbinate. But, you sure sound like you know it all!

The CRC uses twitter and is very responsive in answering kashrus questions posed to them. But please be aware that their opinions are not always in accord with the opinions of the Alter Rebbe on all matters, so please check their answer with your local Chabad Rav if necessary.

Afe these halochos according to the Alter Rebbe and Rabbi Chayim No’eh?

Very helpful thank you

Re: check for sea-horses and mini-shrimp

They would not be chopped up. They would be whole, pressed into the nori, and easily visible to the eye. Just look at each sheet before you use it, that’s all. If you see something that from its shape doesn’t belong there, throw it out.

cheese
September 10, 2013 3:23 pm

parmesan cheese is 6 hours regardless if eaten cold (salad) or hot, these are the opinions of the crc as The Rebbi said many times ,”ask a competent rabbi!!!”

seaweed
September 10, 2013 3:22 pm

Yey!
I saw bulk packs of seaweed at a chinese version of the kollel store, same brand as in the kosher stores but without the kosher label at a fraction of the price (since it was bulk)

Is #4 responding to #3 ?
Thank you.

Check for sea horses and mini-shrimp?
September 10, 2013 3:02 pm

How is that possible?

Chopped up sea horses would be green powder?
And, mini-shrimp need a microscope.

So, how do people see what they look like on a sheet of nori – toasted seaweed..?

A new one should be run every week on COL
