Story Behind this Recipe
This is the custard cream that I usually use. I referenced a dessert cookbook to come up with it. I uploaded a recipe for choux pastry so I uploaded this recipe for the filling cream.
You don't have to sift the cake flour. It's best to mix the mixture continuously over heat! It's also delicious if you chill the custard cream in the fridge and pour caramel sauce on top.
