Ingredients

1/2 cup coconut oil
1/2 lb white chocolate
3.5 oz lady finger cookies, crumbed
3 1/2 cups cornflakes, finely crushed
1 - 13.5 oz can sweetened condensed milk
1 tbsp butter

3-4 None lemons, zest from 2, juice from 3 or 4

Preparation

Grease a 9 1/2 inch loose-bottomed tart pan. Melt coconut oil and chocolate, stirring occasionally. Add cookie and cornflake crumbs then press mixture into base and sides of prepared pan. Chill for 1 hour.
Bring condensed milk, butter, cream, 1/2 cup sugar, 1 cup water and lemon zest to a boil, stirring. Remove from heat. Mix 2/3 cup lemon juice with cornstarch then add to pan, return to heat and bring to a boil, stirring. Simmer for around 1 min until thickened. Whisk 6 egg yolks with 2 tbsp warm cream. Combine mixture with remaining warm cream, whisking, then pour into tart shell and smooth top. Chill for at least 2 hours.
Whisk whites to stiff peaks, gradually adding remaining sugar. Add 1 tbsp lemon juice then spread meringue in swirls over top of cooled tart. Using a kitchen blowtorch, torch meringue until golden brown.
