I wrote a bit about my use of this recipe in a different tread.
The chocolate syrup works great in coffee and milkshakes. I’m not sure if the coconut oil helps much but it doesn’t seem to hurt anything either with the chocolate or the honey, I basically double the amount of lecithin to help emulsify the added oil.
I liked the strength enough to bump it up to 20grams rosin extract per 1000ml finished syrup.
