Roll out some puff pastry (I bought mine, but there is a recipe for it in English Food; I haven’t plucked up the courage, nor had the spare 5 days or whatever to put aside in order to make it) and line a deep plate, or a pie plate. Whisk up 2 egg yolks, 2 ounces of sugar and the rind and juice of half a lemon in a basin or bowl until creamy. This is not as arduous as it sounds, it happens quickly, I assume because of the citric acid in the lemons stabilising the egg proteins. Add an ounce each of ground almonds and melted butter, and whisk the mixture over simmering water for 8 to 10 minutes, I reckon, until it becomes thicker. Pour the mixture onto the pastry and spread the mixture leaving a good gap at the edges and bake at 190 degrees C for 20 to 30 minutes until golden brown on top. Whilst your waiting for that whisk two egg whites and a pinch of salt until stiff, when the pie is done, spread the egg whites over the top and sprinkle over a tablespoon of sugar and return it to the oven for 10 minutes. Eat warm. Foolishly, I forgot to buy cream.
