How to preserve Tagetes Filifolia

From what I understand you should be able to extract the ink and freeze it for later use. Users on this forum suggest extracting the ink and then freezing. Another person here says:

I save my ink from freshly cleaned squid and just freeze it

So it looks like your best bet would be to extract the ink from the sacs into a suitable freezer container and freeze it.

Freezing will definitely help it to last longer as the shelf life of squid in the refrigerator is 1-2 days. You can extend this to 3-5 months in the freezer. I'd imagine the squid ink would have a similar shelf life.

Peel the garlic bulbs and mince (or food-proccessorize) them. Then portion the minced garlic into usable units and freeze those on a cookie sheet. Once they're frozen, keep the lumps-o-garlic in a convenient vessel in the freezer. You can then pull one lump at a time out of the freezer and use it.
