Potatoes (Pommes de Terre)

Pommes de terre (potatoes) begin with one truth: the variety decides the dish. A waxy potato keeps its shape and takes a shining coat of butter. A floury potato opens and softens, magnificent for purée but wrong when the pieces must remain whole. No technique trades one for the other.

The source entry is a market lesson, not a formula. It measured disappointing ordinary potatoes in England against prized Dutch and Vitelotte imports; for a cookable plate, that lesson becomes the simplest classical service, waxy potatoes simmered gently and glazed with a parsley beurre monté (butter emulsified with a little water). The professional luxury here was not a saucier or a stockpot kept full, but access to several varieties and enough hands to trim them identically. At home, small red potatoes and a peeler do the job. Decorative trimming is scaffolding and can go; even size and waxy flesh are the dish and must stay.

Choose one labeled waxy variety and cut every piece to one size before touching the pan. That is the step that matters most. Simmer gently, dry the potatoes well, then let the beurre monté carry the butter into a thin gloss instead of a greasy puddle. One cook, one stove, one evening.
