                                6.

                                7.
                                Mix evenly without dry powder to form a smoother egg yolk paste. Don't make circles when whipping.
                                    
                            
                            
                                8.
                                After the egg whites are beaten with large bubbles at a low speed with an electric whisk, add 30 grams of sugar and change to a medium speed.

                                When a fine foam is formed, pour in the remaining 30 grams of sugar and continue to blow at a medium speed
                                    
                            
                            
                                10.
                                When you feel resistance under your hand and obvious lines appear, pick up the whisk, and when the egg white is at such a big right angle or a big bend, the egg white paste is ready; at this time, start to preheat the oven 170 degrees

                                12.

                                Use the method of turning or cutting to mix into a smooth and delicate cake batter

                                16.

                                Tips: 
                                The linseed oil in the cake can be replaced with light-smelling oils such as soybean oil, corn oil, salad oil, etc.;
 Don’t beat the egg whites too dry, otherwise the cake rolls will crack easily;
 The jam can be rolled into your favorite jam or whipped cream;
 The baking time and temperature are adjusted according to your own oven.
