Le Cordon Bleu graduate. an "ice cave" (an insulated box for storing ice cream), Her cone, which she called a "cornet", was made from
ground almonds and might have been the first portable and edible ice cream cone. but Marshall is nevertheless frequently considered to be the inventor of the modern ice cream cone. In the summer of 1888, Marshall went on a tour to the United States. Her lecture received a positive review in the
Philadelphia Bulletin but she did not achieve the same level of acclaim in America as she had in England. Marshall is recorded to have provided Christmas dinners for the "Hungry Poor" in

Book of Cookery was followed by her third book, ''Mrs A. B. Marshall's Larger Cookery Book of Extra Recipes
(1891), dedicated "by permission" to Princess Helena and devoted to more high-end cuisine than the previous book. Her fourth and final book, Fancy Ices
, was published in 1894 and was a follow-up to The Book of Ices''. The cooking books written by Marshall contained recipes she had created herself, unlike many other books of the age which were simply compilations of work by others, and she assured readers that she had tried out every recipe herself. Among the various foods featured, Marshall's books contain the earliest known written recipe for
Cumberland rum butter. In the 1890s, Marshall also resumed her weekly articles on various subjects in
The Table, writing on both serious and frivolous topics. Among the articles she wrote during this time were musings on the poor quality of food on trains and at railway stations, a denouncement of canned food, a lament on the lack of good-quality tomatoes in her area, support for women's rights, criticism of superstition, and speculations on future technology. She made several correct predictions for the future; Marshall predicted that motor cars would "revolutionise trade and facilitate the travelling of the future", speculated on how refrigerated lorries could be used to deliver fresh food nationwide, predicted that larger stores would bring small provision shops out of business, and that chemically purified water might one day be provided to all homes as a matter of course.

teasmade and
automatic doors. == Death and legacy ==
