Milk bubbles and whipped cream cakes should be baked at high temperature; Heavy cream and Qifeng should be baked at room temperature; Fruit cakes and big cakes should be baked at low temperature. Note: if the baking temperature is lower than the appropriate temperature, the top of the baked cake is often flat and sticky, and the periphery shrinks toward the center. The baking tray is filled with sticky batter, and its internal structure is very soft. If the baking temperature is higher than it should be, the center of the cake bulges upward and the top of the cake breaks, and the outer edge of the cake shrinks inward from the baking tray, but the inner side of the baking tray is smooth, without batter sticking to it, and the internal structure is relatively tight. If the cake is not cooked, there will be a sticky batter on the top under the skin. If there is this sticky batter or waterline near the bottom of the cake, it means that there is too much water in the formula, or the bottom material is not enough, and the grease in the formula cannot be mixed evenly when stirring.
