I give you the exact recipe I took for sure the mercotte site, BUT, I also give you my impressions ....
I took a flexipan biscuit mold, the big one, because 20/30 ca seemed really small compared to the amount of russian background got ..... the dessert i made with this recipe is for 20 people ....
640g of egg whites is not an error it does about 18 eggs ..... it's huge .... yes it's a lot, I think next time I'll MAKE my DAO recipe in which I put 5 egg whites for a dessert of 10 people ....
By cons for the cream pralinee, seen the other quantity I double the volume otherwise we had more biscuit and really a very thin layer of cream ..... view the goods that we put in, as far as it feels a few things ....... and really whisk the sparkling yellows and afterwards ir add the butter well whip also for good performance after.
