Combine the flour, salt and honey in a medium bowl or the bowl of a food processer.
If using a bowl, add butter in chunks and cut finely, using a pastry cutter, butter knife or 2 forks. The butter pieces should be no larger then a pea. Be careful to not over work the dough.
If using a food processor- with the processor running add the butter chunks and continue running until the butter pieces are pea size.
Add to the mixture in either your bowl or processor the sourdough discard starter.
Mix until incorporated. Do not over mix or you will have a tough dough.
Divide the dough into 2 disc. Wrap both disc with parchment paper and put into a plastic bag.
Refrigerate for 2 hours, until set and firm. This dough can be refrigerated for up to 4 days or frozen for up to 3-4 months.
Lightly flour your work area. I like to just keep the parchment paper underneath the dough as I roll it out into a circle or rectangle. I roll the dough out to fit the baking pan I will be using to bake the tart on.
Refrigerate the rolled out dough until the pears and frangipane are prepped and ready to assemble.
