(Chapter 95)
Take as much as you like of similar amounts of sweet and tender carrots, milk, and dates. Put them in a clean soapstone pot, which you lower into a tannur heated with medium fire. Close the bottom vent but leave a finger-wide opening.
Let the pot simmer until the ingredients fall apart. Take it out, and add ground walnuts and 1/2 dirham ground spikenard and ginger. Drench it in sesame oil and serve it.
