Pastry
190g cold cubed butter plus extra for greasing
250g wholegrain YQ flour, or other wholegrain wheat flour, preferably local and/ or organic
50g buckwheat semolina, or use more wholegrain flour
½ tsp sea salt
65g golden caster sugar
1 egg, plus 1 extra to seal the pastry shell, whisked
Kefir custard filling
35g golden caster sugar
1 tbsp wholegrain YQ flour
¼ tsp sea salt
25g unsalted butter, melted
100g local honey – if the honey has set, warm it until runny
2 large eggs
95g kefir
95g double cream
1 tsp apple cider vinegar
12 tsps jam or seasonal compote
1. Grease and line a muffin tray
2. Mix the dry ingredients, from the YQ flour to the sugar, together in a mixer. Add the butter and mix until it resembles breadcrumbs. Add the egg and keep mixing until it starts to come together, then stop the mixer
3. Roll to the thickness of a £1 coin and cut into 10cm discs. Carefully shape the discs into the muffin tray by folding the edges a little. It doesn’t matter if the edges overlap. Use any leftover pastry for biscuits or freeze it
4. Chill the pastry shells in the fridge for an hour or overnight. Once chilled, pre-heat the oven to 180oC and blind-back them for 10 minutes. Remove the baking beans and bake for a further 2-5 minutes or until golden brown. Using a pastry brush, seal each shell with a little egg and return to the oven for 1 more minute or to just dry.
5. In the meantime make the custard. Pre-heat the oven to 160 degrees C. In a large bowl whisk together the sugar, flour and sea salt. Whisk in the butter and honey. Add the eggs and whisk well. Add the kefir, cream and vinegar and whisk until creamy and well-combined. Strain the filling through a sieve into a jug
6. Put 1 tsp of jam into the bottom of each tart shell, then pour the custard mix on top slowly to ensure the jam stays at the bottom of each case
7. Bake in the preheated oven for 18 minutes. After the first 10 minutes, rotate the tray and continue to bake for 8 minutes or until the edges are set and the centre has a little wobble. Leave to just set and enjoy!
