In a large bowl (or the bowl of a standing mixer), rub the lemon zest into the sugar. This releases the oils in the lemon zest.
Add the flour, baking powder, poppyseeds, and salt to the sugar mixture. Mix until combined.
Using a fork or a pastry cutter (or your standing mixer), work the butter into the flour until the mixture resembles coarse crumbs (and the butter is about the size of peas).
Whisk together the heavy cream, lemon juice, egg, and almond extract. Slowly mix the wet ingredients into the flour mixture, mixing until the dough comes together.
Turn the dough out onto a floured surface and form the dough into a flat circle, about 1/2” to 3/4” thick. Cut the dough into 8 equal triangles.
Place the scones on the baking tray, and brush the tops with a bit of heavy cream.
Bake for about 18-20 minutes, or until the tops are lightly golden brown.
Allow to cool for 5-10 minutes.
