Take currants, meat of nuts, crusts of bread and powdered ginger, cloves, ground cinnamon, pound it well together and add thereto salt temper it up with vinegar and mess forth.
Soak bread crumbs in vinegar and ½ cup water, let set for about 30 minutes. Place nuts and currants into food processor. Pulse until ground into fine meal. Add soaked bread crumbs and remaining ingredients into food processor and pulse into smooth sauce is formed.
Notes on the Recipe:
The dominant flavor of this sauce should be cinnamon, as found in similar recipes. The vinegar and water ratios were chosen to not have the vinegar dominate the flavor of this sauce.
Notes on the Transcription & Translation:
The original text and transcription preserve the shorthand of writing that was common practice in the late 14th century. I have taken the liberty of spelling each word fully in my transcription for clarity.
