Ingredient and food-portion control is a kitchen fundamental, but even some experienced chefs dismiss the practice as time-consuming or not necessary. The reality, though, is that the tools of food-portion control are simple and inexpensive. Graduated measures are used for portioning liquids and some dry powdered ingredients, including expensive herbs and spices. Simple ladles can be used to control soup and sauce dispensing. Scales are used for dry-weight portioning of recipe ingredients, sandwich meats and cheese, plus prepared foods, including deli salads, entrées and sides.
Accurate mechanical or digital scales are the basic tools for recipe-ingredient control. In addition to avoiding waste of expensive recipe ingredients, the use of scales helps ensure quality and batch-to-batch consistency. While an experienced chef knows "a pinch" when he or she sees it, less experienced cooks need a simple and easily repeatable way to measure key ingredients.
Mechanical scales are still widely used in foodservice for both ingredient and portion control. (People like the simple analog dial and needle pointer.) For many applications, accuracy to the nearest ounce or half-ounce is adequate. Mechanical scales are available with different maximum weight capacities, which can be matched to fit your classroom's need. For sandwich ingredients, a two- or five-pound (maximum) scale is fine. For example, Winchester, Va.-based Rubbermaid Commercial Product's Pelouze 800 Series (photo, right) washable mechanical portion-control scales are available in 32-ounce and 5-, 10-, 20-, 32- and 40-pound models.
In this digital Information Age, it is no shock that digital scales are gaining the upper hand. Based on sophisticated load cell technology, digital scales are capable of very precise weight measurements; some models display in increments of one-tenth (0.1) of an ounce or in grams. With their solid-state design, digital scales are typically flat and compact, often just two or three inches high, with a large stainless steel load platform that can be removed for easy cleaning. Dayton, Ohio-based Globe Foodservice Equipment Co.'s GPS10 Portion Control Scale (photo, left) can be set to weigh food in pounds, ounces, grams or kilograms, and to display that weight in nice big 1-inch LCD characters. It has a durable ABS plastic body with a stainless steel platter that is removable for easy cleaning.
Cleanability is certainly a big issue with all these scales, especially scales used for portioning deli meats, cheeses and ingredients that will not be cooked. Like any kitchen surface, scales are susceptible to bacterial or viral cross contamination. So scales need to be easy and safe to clean. The new Poseidon WSC-10 Heavy Duty Digital Portion Scale (photo, right) from Edlund Co., Burlington, Vt., has a stainless steel body that is designed to be completely submersible, which makes washing fast and easy. This self-calibrating model is designed for use in harsh environments (aren't all kitchens?), and it offers six display options and has adjustable leveling feet. Edlund also offers a dishwasher-safe mechanical scale in its DOU-2 Model.The only downside to digital scales is that they do require a little electric power in the form of either 9-volt batteries or a plug-in to a 120-volt outlet via AC adapter. But some, like the Globe GPS10, have an automatic shut-off to conserve battery power and save energy when not taking measurements of key ingredients or food portions.
