White Butter Cake (Again)

I promised my friend, J to make the cake again for her to compare to her last attempt, which she complained did not turn up well. My cake turned up fine despite I left it half way after beaten the egg whites, waiting for my hb to return from shop for the flour. I thought I would fail this time as the meringue has returned watery after waiting more than 1 hour but the cake still turned up light & fluffy.
