LLADONOSA’S VERSION OF PARSLEY SAUCE IN LA COCINA MEDIEVAL. SALSA VERDE, p 87 ADAPTED FROM ANÓN SENT SOVÍ #CLXVI, QUI PARLA CON SA DEU FFER JURVERT. pp 179-180
For 6 or more
A few sprigs of parsley
2 slices toasted bread, crust removed
1 c vinegar
¼ tsp white pepper⅓ c honey
salt to taste
Mash leaves from a few sprigs of parsley in a mortar with a pestle. Add the bread soaked in vinegar and pepper. Mix well. Add honey. Mix all again. If the sauce is too thick, more vinegar can be added. Taste for salt. The sauce looks like it is finished but the original recipe recommends that it should be heated with one or two pebbles from the sea until they are red hot. Add the sauce and let cool.
Then the sauce is actually finished. The parsley and pepper help to produce a sweet and sour flavor.
I don’t see that the use of the pebbles makes much difference in the end.
It is served in a “gresal” (grail, cup or goblet shaped glass), the word that we find at the end of the recipe.
 See Medieval Spanish Chef “cañarejo apio.” Aug 2, 12, for version adapted directly from Sent Soví #CLXVI which calls for mint and marjoram as well as parsley, plus garlic and walnuts a opposed to Lladonosa’s version below.
