Begin by cleaning enough strawberries for 300 grams. Then blend it till smooth. Once smooth pass it through a fine sieve. Tap the side of the sieve to speed up the process.
Now mix 225 grams of the strawberry coulis with the cream, the corn starch and the egg yolk.
Mix it well and then while stirring heat it up to thicken the cremeux.
Once thickened add the white chocolate and the zest from the lemon. Then blend it with a hand blender.
Now pour it into a bowl, cover it and let it set in your fridge. After that transfer it into a piping bag and keep it in your fridge.
