Beat the butter, salt and sugar in the raw together until smooth.
Cap the strawberries and cut into slices
Peel and pit the peaches. Cut into small chunks.
Line a baking tray with parchment paper or silicone
When the dough has done its first rise, turn it out onto a lightly floured counter
Roll it out to a 13 x 10 rectangle
Add the sugar mixture and spread to just about the edges.
Sprinkle the fruits around randomly over the sugar mixture.
With the wide edge facing you, tightly roll the dough up like a jelly roll.
Pinch the edge to close and roll it to seal.
Cut the dough all the way through, keeping it intact for just a little bit at the top
Twist the two pieces together, like a two part braid and then bring the ends together to form a circle (like a crown) pinch the two ends together gently to seal. Tuck in any pieces of strawberry or peach that have fallen out.
Carefully place the dough on the prepared baking sheet, cover (I used a linen towel) and let rise until doubled in size. About 30 - 45 min
Preheat oven to 400°
Bake the couronne for 25 - 35 min until risen and golden brown. Turn halfway through baking
Cool on a wire rack
While the strawberry peach couronne is cooling heat the apricot jam with a splash of water. Using a pastry brush, brush the couronne with the jam to give it a nice shine.
Mix the confectioner's sugar and lemon juice to make an icing. Drizzle it over the couronne
Let fully cool before serving
