1. Prepare the milk mochi
   In a saucepan, pour in the milk, starch, and sugar. Heat over low heat, stirring constantly with a spatula.
   When the dough thickens and becomes elastic like mochi, remove from the heat. Spread it out in a container dusted with starch and let it cool in the refrigerator.
2. Prepare the tart shells
   Cut the puff pastry into 12 equal pieces and place them in mini tartlet or muffin tins. Prick the bottom lightly with a fork.
3. Fill
   Add a little filling to the bottom (e.g., almond cream) then place a piece of milk mochi on top.
4. Bake
   Bake in a preheated oven at 180°C (350°F) for about 15 minutes, until the pastry is golden brown.
5. Decorate
   Dust with powdered sugar or add some chopped nuts before serving.

These mini tartlets pair wonderfully with a Hojicha or a creamy Matcha latte.
An original little dessert to surprise your guests!
