I was thinking recently that I have never tried to bake or prepare rhubarb. This is such an lovely ingredient and still I was never even tempted to try. However this time, I realized that rhubarb is actually in season, as I stood in the veg and fruit section in one of my local shops. So I grabbed a packet and decided to make a tart for my friends as they were coming for lunch in a couple of days.
When I make tarts I always prepare my own pastry. I used the shop-bought one a couple of times and I must admit it is an easy option. But I just love making it myself. It is not so difficult and you can most definitely spot the difference in the texture and also in the overall taste. My hands are usually very cold and this is very useful when working with butter. Some recipes suggest to use food processor when starting the breadcrumb process but I prefer to do it myself. In this way I get a better feeling on how much more liquid is needed and how the pastry is binding together.
Rhubarb itself is super easy to prepare. I bought the forced rhubarb which was unfortunately more green than lovely pink colour. But once cooked the colour became paler and lighter. I was unsure whether the round tin will work when arranging the stalk. But then I figured out the way of placing each segment without breaking it too much.
Sweet Treats: Rhubarb Tart (serves 8)
450 g rhubarb, trimmed and cut into 13 cm long batons
1 tsp vanilla essence
50 g caster sugar
juice form 1/2 lemon
225 g plain flour
20 g ground almonds
2 tbsp icing sugar
140 g cold unsalted butter
1 egg yolk
For creme patisserie
250 ml milk
2 egg yolks
2 rbsp caster sugar
1 tbsp cornflour
1 tbsp plain flour
50 ml double cream
Put sugar, vanilla essence and lemon sugar with about 300 ml water in a wide pan or casserole and bring to boil over the low heat. Once the sugar is dissolved add the rhubarb batons and ensure that rhubarb is covered with the liquid. Leave to simmer for about 5 minutes. Then take from the heat and allow to cool. Keep the rhubarb in the sirup for another 1 hour or up to 1 day.
For the pastry, mix butter and flour with almonds and sugar in a bowl. Use your fingers to break the chunks of butter and to create breadcrumb texture. Stir the ingredients every now and then to allow large chunks come to the surface. Then add egg yolk and dribble of 1-2 tbsp cold water. Knead the pastry briefly to allow all ingredients come together and to form a dough. Wrap in cling film and allow to chill for 30 minutes in the fridge.
For creme patisserie, place milk and vanilla essence on the hob and bring to boil on a medium heat. Whilst milk is coming to a boil, whisk the egg yolks and sugar together with flour in a bowl, until pale and light. Pour the hot milk whilst whisking the eggs mixture. Place the mixture back on the medium heat (in a clean pan) and stir continuously until it becomes thick and covers the back of the spoon. Be careful with the heat at this stage, as creme is very likely to stick and burn at the base of the pan. Scrape the creme into a bowl and cover it to prevent the skin formation. Chill for 1 hour and up to 2 days.
Roll out the pastry to about 1-2mm thickness and line the tart tin. Press the pastry into the flute edges of the tin and ensure it is also overhanging the edges of the tin. Chill for another 30 minutes. Heat the oven for 200 C/180 C fan/ gas 6. Line the pastry with a baking parchment and place baking beans on top. Blind bake for 20 min and temvoe the baking parchment. Then bake for another 6-8 minutes until pastry is golden and dry. Whilst pastry is still hot trim the edges of the tin with a sharp knife. Cool in the tin.
Remove the rhubarb from the syrup and set aside. Then bring the syrup to boil until it becomes thick and sticky. Leave on the side to cool down.
Whisk the cream until stiff and carefully fold in the creme patisserie. Fill the pastry case with the creme patiserrie and smooth the surface. Then line the rhubarb on the creme and ensure the whole surface is covered with the rhubarb. Glaze the tart with the rhubarb syrup and chill for 30 minutes.
