We have a good thing going in my family. We all like mayonnaise and bearnaise sauce A LOT so we use a lot of egg yolks. Not wanting to waste food the egg whites go into little containers in the fridge (they keep for weeks!). But conveniently my dad loves everything meringue-y so we get to use up the egg whites quite frequently too.
The whole little family (there’s only three of us; mother, father and me) loved this rhubarb meringue pie. It still has the tang of a lemon meringue pie but is slightly less heavy as no butter or egg yolk in the rhubarb filling.
The pie on the pictures had approx 500 g rhubarb in the filling which was fine taste wise but looked a little silly with all that meringue, so in the recipe below I’ve adjusted the recipe to 800 g rhubarb. It cooks down a lot in the oven, so I promise it’s not too much.
Also, when making the meringue, please note that it needs a lot of beating with an electric whisk and that it’s important the syrup boils and reaches (or almost reaches) 118C.
Rhubarb meringue pie, serves 8
180 g plain flour
100 g softened butter
2 1/2 tbsp cream or water
800 g frozen rhubarb pieces
3 tbsp potato flour (starch)
4-5 tbsp caster sugar
4 egg whites
120 g caster sugar
120 g caster sugar
100 ml water
Mix all the ingredients to the dough in a bowl or using a food processor. Press into a Ø 20 cm pie dish. Bake in a low oven using baking beads at 180C, for approx 10-15 minutes or until golden and baked through. Leave to cool.
Place the defrosted rhubarb pieces in an ovenproof dish and scatter with potato flour and sugar. If using fresh rhubarb I would start off by using less potato flour adding more if needed. Place in a 200 C oven for approx 20 minuter. The mixture should be bubbling, almost caramelised and thickened. Leave to cool.
Make the meringue: Add egg whites and sugar to a clean bowl and beat for 10 minutes with an electric whisk. Meanwhile make the syrup by adding water and sugar to a saucepan and bring to the boil (don’t stir). Remove when 118C (the boiling point for sugar). Add the hot syrup to the meringue and beat for a further 15 minutes, until you have a thick and glossy meringue.
Assemble: Add the rhubarb mixture to the pie crust once both are cool. Spread the meringue on top and burn the edges with a brulee torch. Serve with lightly whipped cream.
