Start with cooking the potatoes and cauliflower so when the patties are ready, all you have to do is mash them to a puree.
Peel the potatoes, slice them into slices about half a centimeter thick (0.2 inches) and transfer to a wide pot. Put allspice and bay leaf in a small cloth bag, close it, and add it to the pot. Add water to cover and a little salt, cover, bring to a boil over high heat, lower the heat and cook until the potatoes are tender. Remove the cloth bag with the allspice and bay leaf. Strain the potatoes but leave a little water in the pot (2-4 tablespoons ). Return the potatoes to the pot and cover.
Meanwhile, cook the cauliflower: cut it into large florets, place in a large pot, cover with water and add a little salt. Cover and bring to a boil over high heat, lower the heat and cook until the cauliflower is tender. Strain, return to pot, and cover.
