Then slowly add the caster sugar, bit by bit until you have a stiff glossy mixture, this can take a while.
Fill a piping bag with the meringue mixture, cut off the tip of the bag and then start to pipe your nests. I like to pipe up high like a cupcake and then just cut the tops off when they are finished baking. You could also start by piping a dot in the centre of your meringue nest, then in one continuous motion going around the dot twice to make a bigger circle, and then going around again on top of the outer circle to make the sides. You should have enough mixture for four nests.
Bake at 120C for 2 hours whereafter they should be crisp and hallow sounding when tapped underneath
If you went with my option (piping high and not flat, then you can now slowly cut the top off your meringues.
For the Compote
Add the cut strawberries and blueberries to a saucepan with lemon juice and water
Cook over medium heat, stirring every so often until the fruit softens and the water starts to evaporate
Takes 5 – 10 minutes for the compote to thicken
To Assemble
To assemble, top your nests with the yoghurt, berry compote and then some fresh mint sprigs. Serve immediately.
