What does butter look like?
Fungi and plant organisms that are their hosts have evolved over the millennia, producing new mechanisms to optimize and extend the longevity of species as well as their roots. Such cooperation involves the mutual exchange of unnecessary and vital chemical compounds [2]. Fungals and plant bodies, which have been co-evolving for millenaries, are also associated with fungi because they exhibit mutualistic relationships with their root systems.

It's marinated oils
Pickling in a mild vinegar brine is among the finest methods for preserving Slippery Jacks. Prior to cooking, peel off the slimy cap cuticle, rinse thoroughly, and parboil the mushrooms for 10–15 minutes in salted water. Pickling brine: Combine 1 liter of water, 250 ml of vinegar (or cider vinegar), 2 tablespoons of sugar, 1 tablespoon of sea salt, bay leaves, allspice, and peppercorns. Pack the mushrooms into sterilized glass jars, cover with boiling marinade, and process in a water bath for 15 minutes.
