“ Pickling in vinegar. In this method the substances, rendered as dry as possible by exposure to the air, are placed in glass or stoneware jars (not salt-glazed) , or wooden vessels, when strong vinegar, either cold or boiling hot, is poured over them, and the vessel at once closely corked or otherwise covered up, and preserved in a cool situation. Meat is occasionally thus treated; vegetables frequently so. See Pickle.
Potting in oil. In this case salad or olive oil is substituted for vinegar (see above) , and is always used cold.

Mrs. Beeton,  Mrs. Beeton's Dictionary of Every-Day Cookery

“ When you have collected all the things you require, turn all out in a large pan, and thoroughly mix them. Now put the mixed vegetables into smaller jars, without any of the vinegar; then boil the vinegar again, adding as much more as will be required to fill the different jars, and also cayenne, mustard-seed, turmeric, and mustard, which must be well mixed with a little cold vinegar, allowing the quantities named above to each gallon of vinegar. Pour the vinegar, boiling hot, over the pickle, and when cold, tie down with a bladder. ”
