Break the biscuits into smaller pieces and arrangethem on the bottom of a serving bowl. I use about 20 biscuits - enough togenerously cover the whole bottom.
Beat the egg whites to soft peaks, then gradually start adding the sugar. Continue beating to get a stiff meringue. To test if the meringue is firm enough, flip the bowl upside down. If it doesn’t move, you’re golden.
Bring milk to a boil. Place your meringue close to the stove - you’ll be shaping the ‘islands’ and dropping them into the hot milk. Take two tablespoons. Use the first one to scoop some meringue and the second one to close the shape.
Drop each ‘island’ into the milk. Don’t overcrowd the saucepan because the ‘islands’ will expand as they poach.
After a couple of minutes, when the ‘islands’ have puffed up, turn them on the other side. When both sides are done, take them out and place them on top of the biscuits in the serving bowl.
Strain the milk and keep it simmering on the stove.
Whisk together the egg yolks, sugar, vanilla extract (or scraped vanilla pod) and cornstarch. Take a small amount of hot milk and pour it over the mixture to temper it. Whisk to distribute the heat.
Take the tempered egg yolk mixture and slowly pour it into the milk. Continue cooking on low heat to avoid the egg yolks from curdling. It’s crucial that you keep whisking. When the cream begins to thicken, continue to cook for another 2 minutes to activate the cornstarch. It’s ready when your whisk begins leaving tracks in the cream.
Ladle the custard cream over the ‘islands’. Give the serving bowl a light shake to distribute the cream evenly.
Chill for a few hours. Serve in a bowl and eat with a spoon.
