Many thanks to David Lebovitz for the original recipe, also to the many people who made comments about Bostock. This is a lovely light French pastry, comprising 3 elements, of which all can be prepared before hand.
Bread, I used Brioche, made into a loaf, from recipe on this Blog. ( Hamburger Buns, soft and light Brioche buns) ( ( bake 30 minutes @ 200 degrees)) can use plain white Supermarket bread, toaster thick sliced.
Almond Paste, NOT. the same as Marzipan. Very easy to make. See recipe below. Store in fridge or freezer.
Syrup to soak bread. Made in small pot on stove.
RECIPE CHANGED SLIGHTLY TO SUIT OUR TASTE
1 1/2 dessertspoons of sugar
3 dessertspoons of water
2 dessertspoons of liqueur, rum, kirsch or amaretto
Few drops orange flower water, (optional)
6 slices of Brioche or plain white bread1/2 inch thick, ( 2 cm)
200g of Almond Paste
2 large eggs
A few drops of Almond extract ( optional)
Sliced Almonds ( flakes )
Berry or Apricot jam, ( optional)
Simmer, sugar and water in small pan until sugar dissolves, cool and add liqueur and orange flower water
Mix until smooth, with hand or stand mixer, ( I used TMX), almond paste , 2 eggs and almond extract if using.
Pre heat oven, 200 degrees ff. line a baking sheet with baking paper.
Place 6 slices of bread on lined tray and brush generously with sugar syrup. ( bread should be soaked through. )
If using jam, spread thinly over bread.
Spread Almond/ egg mixture over jam.
Sprinkle generously with sliced almonds.
Bake until the tops of Bostonian are nicely browned. About 10 minutes, but check at 6 minutes.
Serve warm or at room temperature.
I have removed 2 lots of sugar from the original recipe. Extra sugar was included in the Almond paste egg mix, and some was sprinkled in top of sliced almonds.
I have also added the jam layer, which was not in David’s recipe, but in the comments.
This makes more than needed, but can be frozen and should be stored in the fridge until needed as it contains egg white.
Original recipe adapted from ‘The Spruce Eats.
1 1/2 cups fine powdered white sugar

1 large egg white, lightly beaten.
Few drops of almond extract
Grind sugar in TMX until fine powder.
Add Ground almonds and mix well together
Add egg white and almond extract, mix at speed 6 until it comes together as a paste. Roll in plastic to form a sausage.
