Cherry Bakewell Tarts

- Rub the butter into the flour until it resembles fine breadcrumbs. - Add the egg yolk and sugar and mix with a knife (it?s more effective than a spoon). - Add enough water to bring the dough together you?re aiming for firm but not hard. - If you?ve added too much water and the dough is sticky, don?t panic just add a little more flour. - Wrap the pastry in Clingfilm and refrigerate for at least 15 minutes. - Preheat fan oven to 180?C and grease 12 patty tins i.e. the individual little patty indents - Roll out the pastry between two sheets of greaseproof paper, this saves you having to use any extra flour. However, if you prefer, roll out on a floured board. - Using a 3 1/16in cutter slightly bigger than the diameter of your patty tin indents, cut out 12 circles. You will have to re-roll the pastry to get this many but it?s very good natured and will re-roll several times. - Line the greased tins with the pastry disks and spoon some jam onto each one. I used about half a heaped teaspoon for each tart. - Now make the almond filling. Beat the butter and sugar until pale and fluffy. - Beat in the eggs one at a time, and after each egg, add half of the ground almonds. The mix will curdle but don?t panic as soon as you add the flour it will correct itself. - Add the flour and almond essence and stir well. You can just mix it there?s no need to fold or be careful. - Spoon the mix into each pastry case and bake for 20 minutes. Mine took exactly this time. - Remove from the oven and leave to cool completely before removing from the tin. This is because the pastry is fragile when fresh from the oven and firms as it cools. - Mix together the icing sugar lemon juice, and water until smooth and glossy adjust the measurements as required to get the right thickness. You?re aiming for thick but still runny, opaque and glossy. - Spoon onto the top of each tart. Before fully set, add half a glac? cherry on top.
