I made this with my niece, Josie. We started by making meringues from 3 egg whites and 150 g of caster sugar. For details on making meringue look here.
On a baking sheet covered with baking parchment we made meringue nests buy putting a couple of heaped table spoons of mixture on the tray and shaping it into a nest. These went into an oven at 120 degrees C / 250 F for 2 hours until they were crisp and golden.
We allowed the meringues to cool then put a tablespoonful of crème fraiche in each, you could use whipped or thickened cream instead and the added, strawberries, raspberries and blue berries. Simply delicious!
