To make this galette in advance, you can either make it the night before or freeze it!To freeze the galette, wrap it up, place it in an airtight container, and freeze for 2 months.
For the best ginger pear galette, choose pears that are ripe but still a bit firm. If you want a smoother filling, you can peel the pears, but I like keeping the skin on for extra texture + color.
