I’m a big fan of rhubarb (I’ve decided putting it in granita with lime zest is my favourite way to eat it- I’m sure that could be blitzed into a daiquiri of sorts as well… anyway I digress) and thought I’d take the last stems of the season to make some nutty frangipane tartlets. This recipe calls for pistachios and almonds in the frangipane to create an earthy flavour which I think pairs really well with the tart rhubarb.
For the pastry: 125g plain flour, 70g butter, 1tbsp caster sugar, pinch salt, 1 egg yolk, 2tbsp cold water
For the rhubarb: 75g caster sugar, 100ml water, 2 stems rhubarb
For the frangipane: 50g butter, 50g caster sugar, 1 egg, 75g ground almonds, 75g shelled pistachios (blitzed until roughly ground), 1tbsp plain flour
- To make the pastry, place the cold butter and plain flour in a food processor along with the salt and sugar. Blitz until the mix resembles fine bread crumbs then whisk together the egg yolk and water in a small bowl. Add half this liquid to the crumbs and pulse until they start clumping together. If it still seems a little dry, add another teaspoon of the egg and briefly pulse again. As soon as the dough forms little lumps stop the machine and tip out the contents. Press together and shape roughly into a disc (don’t overwork). Wrap in cling film and chill for 20 minutes.
- Preheat the oven to 190c. Grease and flour four small (about 8cm) tart cases.
- Once the pastry has firmed up a little, roll out to about 2-3mm thick. Line the tart cases, carefully using a little ball of spare pastry to get it right into the corners. Trim away any excess and chill again for 10 minutes.
- For the rhubarb, dissolve the sugar in the water over a gentle heat then bring to the boil. Remove from the hob and add in the chopped rhubarb. Leave it to soften in the hot syrup until required.
- Now it’s time to blind bake the tart cases. To do this just line the pastry cases with some baking paper and baking beans to ensure that the walls are supported. Bake for 10 minutes then remove the baking beans and paper and bake for a further 10 minutes until a sandy consistency is achieved with no grey areas.
- While the cases are baking make the frangipane. Place the butter and sugar in a food processor and blitz until light and fluffy, then add the remaining ingredients and pulse to fully combine (this should take a few minutes). The final consistency should be smooth and creamy (remember, if you don’t have a food processor you can use a stand mixer, electric beaters or a wooden spoon!).
- Now it’s time to assemble. Just place 1-2 heaped tablespoons of the frangipane into the tart cases, smooth out then top with some rhubarb pieces (don’t overfill, remember leave a little bit of room for expansion).
- Bake for 15-20 minutes until the frangipane is golden. Top with some white icing if you like and enjoy warm or cold with a big dollop of creme fraiche.
