METHOD

Pickled cones

Bring water, vinegar and sugar to a boil. When the sugar is dissolved, remove from the heat.

Break up the cones in its segments, and put them into the pickling juice. Leave to pickle in a clean glass jar in the fridge for 2 days. Remove the skin from the segments and remove the tough inner part. Cut into small strips.

Silver fir oil

Heat oil, spinach and needles to 80 Celsius on medium heat. When the temperature is reached, blend it for 10 minutes and strain.

Caramelized buttermilk caramel

Bring the buttermilk to a boil over low heat so it splits. Strain it and keep the liquid. Add the honey to the liquid and reduce until it is medium brown. Add butter and cream. Boil until 108 Celsius on medium heat. Strain and refrigerate.

Hay ash

Do this outside. Set the hay on fire in a big casserole. When the flames are almost out, choke the fire with a lid. Make sure nothing is made of plastic, because it will melt. Blend the ash into a fine powder.

Cowslip gel

Heat water, caster sugar and citric acid to 65 Celsius. Add the flowers. Refrigerate for 2 days. Strain. Add gellan and citras. Bring it to a boil while whisking form time-to-time, strain and refrigerate until set. Blend the set gel into a fluid gel. Strain and taste with silver fir oil and lactic acid.

Shortbread crust

Sift the flour, salt and icing sugar into a bowl. Add the butter and stir until it has the appearance of sand. Add the egg yolk and pinch the dough until it just holds together, Wrap in plastic and refrigerate for 4 hours. Put the oven at 150 Celsius. Roll the dough into a 3 mm thin sheet and line 9 cm tart forms. Make pillows of aluminum foil and salt and put on top of the dough in the forms to press the dough down. Bake for 16 minutes. Remove salt pillows and bake for 4 minutes more. Cool on rack.

Caramelized buttermilk custard

Heat cream to 80 Celsius over medium heat. Bloom gelatin. Add the sugar and iota and blend for 2 minutes. Heat to 80 Celsius again. Add gelatin and blend for 1 minute. Add buttermilk caramel and taste with salt. Leave at room temperature to cool to 25- 35 Celsius while stirring once in a while.

Building the tart

Fill 50g of buttermilk custard in each tart crust. Dust with ash and freeze for 3 hours. Put 25g of cowslip gel onto the custard and carefully smack the tart on your palm to make the gel cover the custard. Freeze for 1 hour. Cut the tart in half. Freeze for 1 hour.

Plating

Start plating 10-20 minutes before serving for the tart to reach the right temperature. Put the half tart in the left side of the middle on a round plate, so it looks like the half of a circle. Put the strips of pickled cones on top of the gel. Serve.
