Quarter or slice the strawberries and toss with all but two teaspoons of the caster sugar in a glass bowl. Allow the juices to seep out; this should take around 20 minutes or so.
Meanwhile, place the remaining sugar, cream, creme fraiche and vanilla bean paste into a stand mixer and whip until soft peaks form.
To assemble place a spoonful of the strawberries into the base of each glass. Crumble a meringue on top, followed by a dollop of the cream. Repeat layers
