Story Behind this Recipe
A long time ago, the wife of a farmer who my mother used to work for gave us this tart! It was so good that we asked for the recipe! It's so tasty that it makes a great present! You really can't fail with this. My friends loved this when I gave it to them as presents.
Divide the tart dough into two, roll out one portion until it's wide and thin, and press it into the cake pan! If you mash the kabocha well, it will be smooth. If you mash it roughly, it will be fluffy. I started off baking it at 340°F/170℃, then when it started to change colour, I reduced it to 320°F/160°C.
