In some periods, caudles were based on milk and eggs, and similar to related drinks like eggnog and posset (a mixture of milk and wine); in others, they were more like drinkable porridge, as in our recipe. As Mary Spaulding explains in Nurturing Yesterday's Child: A Portrayal of the Drake Collection of Paediatric History (1991), gruel becomes caudle by the addition of ale, brandy or wine.
Indeed, Dorothy Hartley’s classic Food in England (1954) quotes a medieval manuscript describing "chef [chaud] ale" (caudle), and six cookbooks dating from 1734 to 1816, according to Spaulding, recommend the addition of wine, but suggest the substitution of ale to make "brown caudle" – we, however, will naturally be using whisky.
In 1714, Mary Kettilby and others published a cookbook by women, for women – or, according to the subtitle, For the Use of all Good Wives, Tender Mothers, and Careful Nurses – A Collection of above Three Hundred Receipts in Cookery, Physick and Surgery. The book’s caudle recipe (see below), which is relatively standard, uses "White or Rhenish-wine", but whisk(e)y should do just as well (though perhaps in a rather smaller quantity).*
A good Way to make Caudle.
To four full Quarts of Water, you may put a Pint of whole Oatmeal; let it boil very slow for five or six Hours at least; then strain it out, and put to two Quarts, three large Blades of Mace, a full Pint and a half of White or Rhenish-wine; and make it sweet to your Taste: And just as you take it off the Fire, slice in a Lemon, from which all the White is cut, which is apt, by lying long, to make it bitter; just the Yellow of the Peel may be put in. A little Salt does very well in Caudle, but is not often used.
There are a lot of cough, cold and fever recipes near the caudle in the Collection – clearly, this would make an excellent tonic for the intrepid cocktail-maker’s wintery sniffles! Otherwise, we can follow Hartley's idea that this "would be a popular brew today in many country pubs as there is nothing at present that well serves a really hungry man who is too tired to eat."
Once you've made your caudle, do as Hartley says: "Drink it as hot as possible – and go to bed at once."
