Note on the Original Text
The recipe uses phonetic and contemporary 17th-century English spellings throughout, like 'hony' for honey and 'Roach Allum' for rock alum. Detailed instructions for heating and combining—even down to the color change—reflect an experimental and observational approach to domestic medicine common before standardization. Such writing is brief, assumes prior knowledge of basic kitchen techniques, and is focused on action (“heat The End of the toungues OR the like Iorn red hott”), with capitalized words for emphasis. Specific quantities (as multiples or fractions) show an emerging literacy in measured preparation, though flexible to the user's judgment.

This recipe originates from a family manuscript of the Granville family, dated approximately between 1640 and 1750. In this period, medical recipes often circulated in household compilation books, some written by women of the elite or gentry households responsible for family health. Sores and cankers in the mouth (likely aphthous ulcers) were a common complaint, and householders would turn to such tried-and-tested remedies that relied on available apothecary ingredients. The blending of honey and alum shows a strong awareness of natural antiseptics and astringents used to treat wounds before the discovery of antibiotics. Metallurgy was respected in early-modern England, with pewter and silverware indicating higher social status and a belief in their purifying virtues—here invoked in the preparation process.

Historically, the mixture would have been prepared in a pewter or silver dish—a sign of both wealth and medicinal purity, as metals were considered to have curative properties. The key tool was an iron rod or the end of a metal utensil (such as a tongue depressor or similar stick), which was heated until red-hot in the fire, then used to stir and partially cook the mixture—harnessing both heat and chemical reaction. Application would be with a small scrap of clean linen rag, wound around a stick or rod, to precisely dab the mixture onto the mouth sores. Open-hearth fires would have provided the necessary heat for the tasks.

Ingredients
- 3.5 ounces honey (raw honey preferred)
- 1.75 ounces alum (potassium aluminum sulfate, as substitute for 'Roach Allum')
Instructions
- Begin by measuring out about 3.5 ounces of clear, runny honey—ideally raw for maximum antibacterial effect.
- Take 1.75 ounces of alum (potassium aluminum sulfate, available in pharmacies or specialty spice shops) and gently heat it in a dry pan until it just begins to char and turn slightly gray, simulating the old instruction to 'burne it.' Let it cool, then grind to a fine powder using a mortar and pestle.
- Combine the still-warm powdered alum with the honey in a small metal bowl (preferably stainless steel or silver, to mirror the historical pewter or silver dish).
- Heat a metal spoon or skewer directly in a flame until red-hot (taking great care!) and then use it to stir the mixture vigorously, keeping the utensil hot by reheating as needed.
- Once the mixture turns black (an indicator of caramelization or chemical change), let it cool slightly.
- To use, dip a small clean piece of gauze or cloth on a stick into the mixture and gently dab it onto the sore in the mouth three or four times a day.
- (For safety, in modern times, you should not use a red-hot metal tool or extremely hot mixture inside the mouth—allow to cool to a safe temperature before application!):

Cooking Estimates
Preparing this remedy just takes a few minutes to measure, burn, and mix the ingredients. Most of the time goes into safely heating and stirring the mixture until it turns black. The finished recipe makes enough for about 10 small uses. Each use only has a small amount of honey, so the calorie count is low.
