I’ve been working brunch for the last couple of weekends, and will do so until I master all of the stations. It is not my favorite meal to cook or to eat but it is important in restaurant life because it is a big cash cow in terms of profit against food costs. Think about it - how much does an egg actually cost?
Currently I’m stationed on the grill. This means I cook many brown foods. Sausage, rib eye, Monte Cristo sandwiches. And our breakfast potatoes.
Breakfast potatoes: I’m of the opinion that they should either be very, very simple (potatoes, salt and fat) or very extensively seasoned (garlic, onion, red pepper flakes, scallions, whatever vegetables are lurking in the fridge). Too many cooks go half way, adding a teeny tablespoon of stale paprika and one insipid diced green pepper to their hash browns. Why bother? Salt and fat alone are enough to celebrate the simple earthiness of this humble vehicle for ketchup and yolk.
To prepare for brunch at the restaurant I go in a few hours before service - first one in -and sweat over six burners churning out 80 potatoes worth of röstis so that I can reheat them on the griddle for each order. These are our breakfast potato, shredded pancakes, Swiss in origin, no binder, crispy and golden brown like a McDonald’s hash puck on the outside, fluffy and snowy white on the inside. Strictly the potato and fat variety of breakfast starch, and simple, but delicious and impressive when done well.
Röstis are a challenge at first - we made them in school with mixed results - but as potatoes are inexpensive it is worth practicing at home. You really need a nonstick pan and a heat-resistant spatula to make these, or you’ll have all sorts of problems with flipping them over.
Heat your pan over a high flame, add enough oil or clarified butter to coat the pan with a 1/4″ slick, let it get hot while you shred enough peeled Idaho potato to make a cake that covers the bottom of the pan to 1/2″ thick. When the oil is hot, add the potato, jiggle and shake and form a round tightly packed cake. Walk away for a couple of minutes, use the spatula to dig under the cake and rotate it so it works evenly, and flip when the bottom is brown and creates a firm crust. Just turn it over. Don’t think about it too much. Then let it get brown and crisp on the second side.
Once you get the hang of constantly moving them so that the crust colors evenly, cooking them fast enough so that the starch on the interior doesn’t discolor, and using enough clarified butter so that they fry without scorching, cranking through 50 or so of them is only a challenge of self-hydration and time. And as noted here before, practice makes better if not perfect.
