Note on the Original Text
This recipe is written in typical 17th-century English, marked by creative spelling and a casual, conversational tone. 'Clarifie' means 'clarify,' and 'beten' is 'beaten.' 'Vatell' is likely 'until.' The writer uses '&' for 'and,' and measures are loose, suggesting an experienced cook's intuition. Testing with a 'spoone' and 'boyling' are familiar kitchen actions of the era. Recipes were often short and direct, assuming prior knowledge of the process.

This recipe originates from the manuscript of Mary Smith, dating to around 1662, in England. During this period, sugar was commonly sold in large, impure loaves, requiring clarification to remove molasses and debris. Clarifying sugar was essential for elegant confections, preserves, and syrups, and was a domestic art practiced by the well-to-do or their kitchen staff. The use of egg white as a clarifying agent was a widespread culinary technique in historical Europe, as proteins in the egg white trap impurities and help them rise to the surface, making them easy to remove.

In the 17th century, the sugar would have been clarified in a brass or copper skillet or pan, over an open hearth or charcoal chafing stove. A wooden spoon was used for stirring. Cooks would drop spoonsful of syrup into water, possibly in earthenware or pewter bowls, to test for clarity. Skimming was done with a small ladle or spoon, and the clarified syrup could be strained through muslin, linen cloth, or a sieve.
