Okay! We are on the home stretch!
Depending on the size of your mold, you want to aim for a 2:1 ratio of dough to pastry. Or if you like a lot of filling like I do, do a 1.5:1 ratio. With mine I was able to measure 1 1/2 tbsp of dough and 1 tbsp pineapple filling.
Measure out the filling and the dough and round out in little balls.
Lightly grease all your molds to help the easy removal after baking.
Once ready, gently flatten the dough into an even circle. I do this on top of some plastic wrap for easy removal. They still will be soft.
Place the filling in the middle and gently encase it in dough. It might be a little tricky at first to master, but just make sure no filling is expose because this can ruin your pastry.
Gently push into your lightly-greased mold.
If you have a pineapple shaped mold like mine, you can portion out some dough, 100g or so (about 1/4 cup) and mix with drops of green food coloring until it turn into a leafy green color. I tried Matcha, but the flavor was too strong.
Repeat for all your filling. Then let rest in the fridge until ready to bake.
