Mustard is my favorite condiment, I don't know what a ham and cheese sandwich would be like if mustard didn't exist. Luckily mustard has been in existence for almost all of time and the first recipe showed up in 42 AD. Mustard is made from crushed mustard seed that is flavored with some sort of liquid: water, wine, vinegar or beer and seasonings. It was brought over to the new land by the colonialists and the first advertisement for the first jar of mustard to be sold in America was published on today's date, February 15, 249 years ago in 1758. A certain Benjamin Jackson wrote the following advertisement in the Philadelphia Chronicle:
BENJAMIN JACKSON, Mustard and Chocolate maker, from London, now of Laetitia-Court, in Market-Street, Philadelphia, Prepares the genuine Flour of Mustard-seed, of all Degrees of Fineness, in a Manner that renders it preferable to the European, or any other, which is easily demonstrated by Proof. It excels all other for Exportation, and it will keep perfectly good any reasonable Time, even in the hottest Climates, and is not bitter when fresh made, as other Mustard is, but when mixed only with cold Water, well seasoned with Salt, is fit for immediate Use.
There you have it, the official first ad for mustard for your enjoyment. I wonder how he demonstrated that his mustard was preferable to that produced in Europe. I would have liked to see good old BJ prove it.
