A1 is a stake sauce that is marked in the USA as a condiment ment to be used on meats or geme dishes.
A1 is marketed as a steak sauce in the USA and condiment for use with meat or game dishes. It was developed, produced and marketed in the United Kingdom as a brand in the year 1831 and was later introduced to the United States by G.F. Heublein and (&) Bros., and was officially registered as a trademark in North America in 1895. The original sauce upon which A.1. is based was created in 1824 by Henderson William Brand, a chef to King George IV of the United Kingdom. A popular myth has it that the king declared it 'A.1.' and the name was born. It went into commercial production under the Brand & Co. label in 1831, marketed as a condiment for 'fish, meat and fowl', and continued production under this label after bankruptcy forced ownership of Brand & Co. to be transferred to W.H. Withall in 1850. It was renamed A.1. in 1873, after a trademark dispute between creator Henderson William Brand and Dence & Mason, who had since purchased Brand & Co. from Withall.
