[Modernist Cuisine at Home] Potato purée

[Anonymous Modernist 16644]

When I combined the prepared 500 grams of potatoes with the 200 grams of butter it was so liquid I could not add the required warm milk! What did I do wrong?

You probably did nothing wrong. There’s a lot of butter in the recipe! To a lot of people, it would probably look thin—we just like it that way. Feel free, however, to adjust the ratios to your liking. Hope that helps!

You did well. But, make it in small quantity like 2 potatoes some part of butter and after that you can judge easily what is it wrong ?
