Tradition of advent calendar, but usually more for children, to have one chocolate each day of December before Christmas
Bolti is a Chocolate Advent Calendar more for adults. A ceramic sphere contains 24 chocolate stick, one for each day before Christmas. Only the upper part of the stick (where the date of the month is written) is visible. In this way, when you pick the chocolate of the day, you get a surprise about the flavor:  There is different chocolate ganache and coated: vanilla, almond, cardamom, cinnamon, sesame etc.
To make the chocolates we made thermoformed mold in plexiglas material to mold the half part. We use a similar industrial process as the plastic moulding but using chocolate.
