Master Chef 3 will be a follow-on achievement after completing the Master Chef achievement. You will need to complete the production of 1500 items in the Bakery. The in-game medal system will require you to complete the bronze, silver and gold medal goals to complete this achievement. The 300 items produced to complete the Bronze and Silver medals will count towards the 1500 total needed. Bakeries can be built and levelled to level 2. Producing Dough that requires flour resources to be available or Berry Pies that require Dough and Berries resources to be available will count towards the completion of this achievement. Aligning a bakery resident to work in the bakery and levelling that resident will reduce the time to produce items in the bakery.
