4 eggs, at room temp.
3/4 c. sugar
3/4 c. sifted flour
3/4 tsp. baking powder
1/4 tsp. salt
1 tsp. lemon juice
1/2 tsp. vanilla

Beat eggs, baking powder and salt with electric mixer until thick and light in color. Gradually add sugar, beat vigorously until it rises in the bowl. Fold flour in by hand, then add lemon juice and vanilla.

Line a greased jelly roll pan with waxed paper. Pour or spread batter evenly over pan. Bake 12 to 14 minutes at 400 degrees.

When baked, turn out onto dampened towel that has been dusted with powdered sugar. Quickly remove paper - while still warm, roll cake lengthwise in the towel, enwrapping the cake. When cool, unroll and fill with whipped cream, fruit, etc. Garnish with whipped cream.
