The ingredient list omits how the moisture content of sheep's milk ricotta will dictate the structural integrity of the crumb. Fresh ricotta contains variable amounts of whey, and dumping it straight from the tub into the batter without draining can produce a heavy, wet center that fails to bake through properly in the specified fifty to sixty minutes at 180 degrees Celsius. Weighing the flour carefully against a full 220 grams of cane sugar prevents the structure from collapsing under the weight of the dairy.
Folding frozen raspberries directly into the batter requires a light touch, as they release liquid into the surrounding crumb during baking, creating localized pockets of moisture. Using fresh fruit instead changes the internal dynamics entirely, yielding less bleeding of color into the batter and firmer fruit pockets, but it also reduces the total moisture introduced during the bake. Thawing and draining frozen berries beforehand is counterproductive because they will disintegrate entirely when stirred.
Baking this cake in a standard 22-centimeter round tin demands vigilance near the fifty-minute mark. Insert a wooden skewer into the thickest part of the center to test for doneness; it should emerge clean without wet batter clinging to it before the cake is removed from the oven to cool.
