Pound two ounces of celery seed in a mortar, and steep it for a fortnight in a quart of vinegar. Then strain and bottle it.
Nearly fill a wide-mouthed bottle with the fresh green leaves of burnet, cover them with vinegar, and let them steep two weeks. Then strain off the vinegar, wash the bottle, put in a fresh supply of burnet leaves, pour the same vinegar over them, and let it infuse a fortnight longer. Then strain it again and it will be fit for use. The flavour will exactly resemble that of cucumbers.
Make a quart of the best vinegar boiling hot, and pour it on four ounces of scraped horseradish. Let it stand a week, then strain it off, renew the horseradish, adding the same vinegar cold, and let it infuse a week longer, straining it again at the last.
Peel and chop fine four ounces of shalots, or small button onions. Pour on them a quart of the best vinegar, and let them steep a fortnight; then strain and bottle it.
Make garlic vinegar in the same manner; using but two ounces of garlic to a quart of vinegar. Two or three drops will be sufficient to impart a garlic taste to a pint of gravy or sauce. More will be offensive. The cook should be cautioned to use it very sparingly, as to many persons it is extremely disagreeable.
