Marmalade

Marmalade was a jelly.

Marmalade was invented in the late 18th century. According to legend, it was invented when Marie Antoinette, who was ill, requested a fine orange cake, and her cook was so worried she ruined the cake, but invented marmalade, called so because she kept saying "Ma'am est malade" while making it.
