Finally pre-heat the oven at 175°C and bake the dough for 20min after pricking it again so that it does not swell.
Like all recipes, it did have to be tested and tasted, here is my little one at "work". Both her and my husband really liked it. He liked it so much that he requested one to bring to work!
The one I made for my husband at work was great! Following the advice from my mum and some friends, I managed to make a great meringue!
Cold eggs, cold metal bowl, a pinch of salt, starting whisking medium speed then faster, once the eggs were stiff, I added the sugar slowly while whisking again at medium speed. It worked!!!! And also I baked it with the oven slightly open to let the humidity go out rather then stay in.
Result: nice and crispy on top.
My mistake: close the oven over night leaving it inside, it is gone a little soft again.
