Cast Iron Grill Press

Contact Is What Produces Crust

Food that curls or sits unevenly touches a hot surface at a few points, which means most of it browns poorly.

A weight holds the whole surface in contact, which produces even browning across the entire face.

That is why smash burgers, bacon and flattened chicken all benefit, and it is the specific mechanism a press provides.

Never Press A Cooking Burger

Pressing a burger that is already cooking squeezes out rendered fat and juices, which is the flavour and moisture leaving the food.

The smash burger technique presses raw mince once at the start to form contact and then never again, which is entirely different.

Pressing repeatedly through a cook is the single most common barbecue mistake and it produces a dry burger every time.

Preheating The Press Matters

A cold press on hot food cools the top surface while the bottom cooks, which slows everything and produces uneven results.

Leaving the press on the grill to heat before use means it contributes heat rather than absorbing it.

For bacon and sandwiches specifically, a preheated press cooks from both sides and roughly halves the time.

Ribbed Or Flat

A flat press maximises contact and produces even browning, which suits burgers, bacon and sandwiches.

A ribbed press produces marks and contacts less of the surface, which is largely cosmetic.

Flat is the more useful shape for almost every application, and ribbed presses exist mainly for appearance.

Seasoning And Care

A cast iron press is seasoned like any cast iron, and a bare one rusts and sticks to whatever it touches.

Washing without detergent, drying completely and wiping with oil is the routine, and a press left wet rusts within a day.

Enamelled presses avoid seasoning entirely and chip if dropped, which is the usual cast iron trade.

Size relative to what is being cooked determines usefulness, since a press smaller than a burger holds down the middle and lets the edges curl. A press covering the whole item is what produces even contact. Round presses suit burgers and rectangular ones suit bacon and sandwiches, which is why people cooking both end up with two.

Handle material determines whether a press can be picked up once hot, and a bare cast iron handle requires a glove where a wooden or coiled one does not.

Weight is the property doing the work, and a light press needs pressing down by hand where a heavy one sits under its own weight and leaves both hands free. Around a kilogram is the point at which a press works unaided.

Storage needs a dry place, since a press left on a grill under a cover collects condensation and rusts exactly as any cast iron would.

Using it as a weight for bacon is the application people find most useful, since bacon curls immediately and a press holds it flat through the entire cook.

Two smaller presses are frequently more useful than one large one, since they cover several items independently.

The Verdict

An effective tool for contact and crust, where the smash technique and not pressing later are what matter.

Pressing during cooking dries food, cold presses slow cooking, and bare cast iron rusts quickly.

Press once at the start or not at all. Squeezing a cooking burger pushes out everything worth eating.
