Start by blind baking your crust in the tart pan. I fill my crust with a piece of parchment and weigh it down with beans or rice while it bakes for an even cook on the crust. this also helps the crust to not shrink down into the pan as it bakes. Bake the crust at 350° for 15 minutes or until it is a pale golden brown color.
While the crust is baking, make the curd. In a small pot, combine cranberries, sugar, ginger, and orange zest and juice. Cook this on medium heat until the cranberries burst and become soft. You can use an immersion blender at this point if you'd like to extract more color from the cranberry skins but this step is optional.
Strain the cranberry mixture through a layer of cheesecloth to get all of the solids strained out. This is best to do in 2 batches so you can squeeze the liquid through the cheesecloth.
When your cranberry mixture is strained, mix in your eggs and egg yolks. If the mixture is still hot you will need to temper the eggs by adding a little bit of the cranberry mixture to the eggs at a time. Return the mixture to low heat stirring constantly until the mixture is warmed through. It just needs to be warm enough to melt the butter. Do not let it boil!
Finish the sauce by adding in your butter and heavy cream, stirring until all the butter has melted and the mixture is nice and glossy.
Remove your crust from the oven and pour in the cranberry mixture. Return to the oven and bake for an additional 10 minutes, until the curd is just set. remove and let cool.
