Fresh Strawberry Jelly Roll With Just Whites

Directions

1. Preheat oven to 375F. Cover a 10 x 15 inch jelly roll pan (or possibly cookie sheet with sides) with parchment or possibly waxed paper.
2. Whisk Just Whites with hot water in a large bowl and let sit for 2 min or possibly so. Whip with an electric mixer until stiff peaks form, gradually adding sugar.
3. Add in vanilla, lemon juice, orange zest and flour and mix in gently. Don't over-mix. Pour into pan, spreading proportionately.
4. Bake 20 min or possibly till golden. Remove from oven and cold 10 to 15 min.
5. Place sheet of parchment or possibly waxed paper on flat surface. Loosen edges of cake with spatula and invert over parchment paper. Lift off pan and carefully remove baked parchment paper by folding far edge back and gently pulling paper toward you. Don't lift parchment quickly, or possibly cake will tear.
6. Just before serving, spread a thin layer of preserves proportionately over cake.
7. Arrange strawberries over entire cake surface. Roll up cake lengthwise, using parchment to lift edges as cake rolls. Place cake, seam side down, on serving plate and slice just before serving.
