Tant pour tant (500g or 300g)

ttcontest

The first video shows to make 500 g of Tant pour tant and the recipe shows to use only 300g.

Which one is it?

Both figures are correct - the first video will indeed make 500g of tant-pour-tant if you use the quantities shown, and the Macaron batter mixture does indeed only need 300g of tant-pour-tant relative to the other quantities given.

So yes, if you want to make only as much tant-pour-tant as you need, then you will have to scale one of the recipes
