Mix together all of the ingredients except the PreGel Maxima Bitter Cream in a mixer with the paddle attachment on low speed until the dough comes together.
Wrap the dough with plastic wrap and place in the refrigerator for at least 1 hour.
Sheet or roll the dough out to the desired thickness and line your tart rings.
Bake at 180°C/356°F for approximately 15 minutes or until golden brown.
Once the shells have cooled, pipe in PreGel Maxima Bitter Cream.
Place back in the oven for 5 minutes and then allow to cool down completely before serving.
