To make base: Preheat oven to 180 C / Gas mark 4 and lightly grease a 22x33cm (9x13 in) baking dish. In medium bowl combine butter, 200g flour and 1 tablespoon sugar and blend together with an electric mixer. Press mixture into bottom of baking dish and bake for 15 minutes, until set.
To make filling: In large mixing bowl combine 6 egg yolks, 4 tablespoons flour, evaporated milk, 400g sugar and rhubarb. Stir together and pour over cooled base. Bake for 1 hour, until set.
To make meringue: In large mixing bowl, beat 6 egg whites until foamy. Beat in 150g sugar and vanilla until stiff peaks form. Spread meringue over rhubarb and bake 10 to 20 minutes, until golden.
This is an excellent recipe, I made this this morning but because I didn't have enough rhubarb I added some apple and a little Cinnamon, the meringue turned out lovely as this Torte is so easy to make, I shall certainly make this again, thank you for sharing this super recipe xx - 19 Jul 2013
