"10 librae of roasted cocoa, cleaned and coarsely minced (1 libra = 12 oz.)
fresh jasmine petals
8 librae white sugar
3 ounces vanilla flowers
6 ounces cinnamon
2 scruples (7.76 grams)ambergris "

I'd worry about the ambergris myself.

Note that the recipe calls for "8 lbs" sugar. Making vanilla sugar is simple enough with the beans (and obviates the need for the blossom); while if you don't live in the Frozen North(TM), jasmine is dead easy to grow.
