Wait, mayonnaise has a military origin? I know hard to believe but this incredible spread does indeed spring from the battlefield.
In 1756 The French army was finally successful in removing the British forces from Port Mahon on the island of Minorca. The siege and blockade, led by the French Duc de Richelieu, was so successful in cutting off supplies to the British garrison that when the French finally took control of the port there was not much there.
The Duc’s chef was tasked with coming up with a victory banquet and even came up with a new sauce to go on the salad course. This sauce became known as Mahonaise after the port.
No siege, no mayo. Amazing how things work.
