This makes a HUGE cake. A pan with a removable center will make extracting the cake much easier. Except for mixing the liquids, an electric beater is useless for this recipe. In the USA, candied fruits typically come in packages of the indicated sizes. I prefer citron instead of the mixture because there's no bitterness from the rinds, although the cake isn't so colorful.
Calmyra figs are the light-colored figs most commonly seen in North America.
Fruit and nut quantities are somewhat flexible.
