USB PROGRAMMING UPLOADS Allows operator to load program settings and user options using a standard USB flash drive

Microw ave Cooking
Microwave cooking uses high frequency energy waves to heat the food. When cooking, microwave energy causes food molecules to move rapidly. This rapid movement between the food molecules creates heat, which cooks the food.
Is it safe to run a microwave if it is empty?
Running a microwave without a load can cause serious damage to electrical components. When food is placed in the oven, microwave energy generated by the magnetron is absorbed by the food. When no food is in the oven, there is nothing to absorb the energy. The energy bounces around the cavity and is channeled back through the waveguide. This can cause arcing, fire and may burn out the magnetron.
How do you defrost food while using a commercial microwave?
Not all commercial microwaves have the defrost button that is commonly found on a residential microwave. To defrost, simply use 20% microwave power level.
How do you know if a container is microwave safe?
To test if a container is microwave safe, place it in the microwave next to a container of water that is micro-wave safe. Run the microwave for one minute. If the tested container is warm or hot, it is not microwave safe.

Cooking Guidelines

The ACP Microwave Oven can make your job easier. You’ll cook ahead and pre- portion more. You’ll also spend less time preparing special-order dishes.
To be sure of consistently good results, you’ll want to remember a few simple guidelines.
Food Variables
Microwave cooking can be directly affected by different food variables.
The sha pe of foods can greatly affect the amount of cooking time. Foods that are flat and thin heat faster than foods which are chunky. For example, a casserole will cook faster in a flat dish, rather than if heaped in a small dish. Foods cut into small pieces will cook faster than large-shaped foods. Pieces should be of a uniform size and shape for more uniform cooking, or the smaller pieces will cook faster. The greatest amount of cooking takes place within 3/4″ (1.9 cm) of the food’s surface. The interior of large food items, or dense foods, is heated by the heat conducted from the outer food layer. The most uniform cooking occurs in flat, doughnutshaped foods. For best results, cook foods together which have similar sizes and shapes.
The qua nt it y or volum e of a food can affect the amount of cooking time. As the volume of the food is increased, the time required to cook or heat the item increases almost proportionately. If twice the amount of food is placed in the oven, it will take almost twice as long to cook. To determine the time for larger quantities, multiply the individual serving time by the increased amount, then reduce the total cooking time by about 20%.
The de nsit y of foods can greatly affect the amount of cooking time. Porous foods, such as breads, cakes or pastries, will heat much more quickly than dense meats of the same size. Porous foods absorb microwaves quickly throughout. Meats absorb microwaves mostly at the exterior surface, and the interior is heated by conduction, increasing the cooking time. Meats can be cooked in a sauce, if desired. Due to the moisture content, a sauce will heat rapidly. The heat will transfer to the meat, so the meat will heat faster due to heat by conduction as well as by microwaves.

The st a r t ing t e m pe rat ure of foods affects the amount of cooking time. Each temperature degree that the food item is to raise must be supplied with a definite amount of energy. Lower initial starting temperatures require more energy and more time to cook. Therefore, refrigerator temperature foods require a longer cooking time than do room temperature foods. Foods already slightly warm will heat very quickly in the oven.
The m oist ure c ont e nt of foods affects the amount of cooking time. The higher the moisture content is in a food the longer the amount of cooking time.
The sa lt , fat , a nd suga r c ont e nt of foods affects the amount of cooking time. Foods containing high salt, fat, and sugar levels heat very quickly and may reach much higher temperatures than foods having low salt, fat, and sugar levels. Foods having lower salt, fat, and sugar levels require longer cooking times.
The a rra nge m e nt of food within a microwave oven cavity affects the way in which the food cooks. A “round” arrangement is best. Use round utensils whenever possible. Also, arrange foods such as baked potatoes in a circle, rather than in rows, for cooking. When only one food item is being cooked, place it in the center of the oven glass shelf for cooking.

Cooking Guidelines (continued)

Manipulation of Foods
Sometimes recipes suggest manipulating or moving food during cooking. There are several forms of manipulation:
St irring is required less often in microwave cooking than in conventional cooking. In conventional cooking, you use a spoon to move food up from the bottom of a pan to evenly distribute the heat. In microwave cooking, you still stir to redistribute the heat within some foods, but you need to stir from the outside of a dish toward the inside or center. If a recipe states to stir once or twice during cooking, stir at approximately even intervals. For example, in a 12-minute cooking period, if a recipe states to stir twice, stir after 4 minutes of cooking and again, after 8 minutes of cooking. However, it is not necessary to be precise. Stir only when necessary. When using lower power levels or settings, less stirring is required. Some examples of foods which may require stirring are puddings, some casseroles, some sauces, some soups, and some egg dishes. Some foods can’t be stirred. These foods are rearranged or turned.
Some foods can’t be stirred and should be re posit ione d or re a rra nge d during cooking. Some examples include baked potatoes, cupcakes (in custard cups), chicken pieces, and others. Rearranging allows for more even cooking of foods. Foods which are cooked, covered, or which are cooked using lower power levels, usually require little rearranging.
There are actually t w o t ype s of t ur ning. Turning is done when foods cannot be stirred. Foods which are cooked, covered, or which are cooked at lower power levels usually require little turning.
Tur ning foods ove r: Turning foods over is done to distribute heat. Meat and poultry are two types of foods which are sometimes “turned over.” Examples include roasts, turkeys and whole chickens. Small meat items such as poultry pieces may need to be turned over when in casseroles, or when in a browning skillet.
Rot at ing or t ur ning dishe s: There are a few foods which cannot be stirred, rearranged or turned over. Therefore, the actual cooking dish is turned or rotated. A half-turn means to grasp the dish and turn the portion of the dish that faces the oven door around, until it faces the back of the oven. Examples of foods which are sometimes turned or rotated in a cooking dish include cakes, quiches, or soufflés. When cooking foods at lower power levels or Settings, less turning of the cooking dishes is required.

Microw ave Utensils
Never use cooking containers or covers with any metal content. This includes all metal and enameled metal-core ware, foil, and metal-trimmed containers. Suitable cooking containers include those made of paper products, glass, china, cloth, and wicker baskets.

RECOMMENDED Plastic amber high temperature pans with lids Microwave safe plastic bags for individualized serving portions Glass/Ceramic
Natural fiber cloth
Non-recycled paper
Plastic
Wood

NOT RECOMMENDED Aluminum foil
Grocery bags Recycled paper Lead crystal Newspapers Metal Metallic trimmed china

UTENSIL CHECK TEST Use the following test to check utensils for microwave safeness. 1. Place glass measuring cup of water next to empty dish to
be tested in microwave oven. 2. Heat on full power for one minute. 3. Check temperature of dish and water.
· If dish remains cool and water is hot, dish is microwave safe.
· If dish is slightly warm, use for short term cooking. · If dish is hot and water is cool, do not use. Dish remains
cool if not absorbing microwaves and microwaves are being absorbed by water. Dish becomes hot if absorbing microwaves.

Cooking Hints
Cove r foods for fa st e r, m ore eve n c ook ing. Glass lids, plastic wrap, plate covers or other paper products may be used. Do not seal. Instead, allow for steam-venting at all times.
Pierce pouches, plastic w rap covers and all foods with a thin skin or membrane, such as potatoes, squash, tomatoes, eggs, etc. This prevents an eruption in the oven and allows for expansion and/or the escape of steam.
Foods should be c a re fully plat e d. For best results, arrange food such as vegetables or casserole-type items evenly around the edge of the plate with slightly less depth in the center. The edges of food items should not overlap or overhang the rim of the container. Cover meats with gravy or au jus and moisten all dry foods other than bread or pastry items.
Do not stack food or plated dishes in your oven. Instead, when cooking more than one serving or platters, all plates should be placed at the same level in the oven, with space between all containers.

Cooking Instructions
Steaming Tips
1. Cook ing Ve sse ls a. Always heat or cook food items in covered containers to accomplish: · Retention of steam for efficient cooking and to keep foods moist · Even cooking results and temperatures · A cleaner oven interior and prevention of food splatters b. Ceramic, paper, china, styrofoam, glass and plastic are suitable materials for use in microwave ovens. A high temperature resistant amber pan is recommended for ALL items, especially those high in fat or sugar content, as these ingredients get hot very quickly.
2. Food Te m pe rat ure a. To reach a mandatory serving temperature, frozen foods require a longer cook time than refrigerated items. b. Refrigerated items: · Items stored at 40°F (4°C) in the refrigerator should be covered while heated; except breads, pastries or any products with a breaded coating, which should be heated uncovered to avoid softening. c. Room temperature items: · Foods held at room temperature, such as canned items or vegetables, will require less time to heat than refrigerated items. d. Conventionally prepared foods should be slightly undercooked to prevent overcooking when rethermed by microwave steaming. e. After a steaming cycle has been completed, internal food temperatures continue to slightly rise due to the presence of steam.
3. St ruc t ure of Food a. Food items that are high in fat, sugar, salt and moisture attract and quickly absorb microwave energy, allowing for a shorter cook time. b. Items high in protein or fiber require a longer cook time, due to a slower absorption of microwave energy.
4. Qua nt it y a. As the mass of food increases, so will the necessary cook time.
Refer to and comply with all USDA/FDA Food Code guidelines when cooking or heating food items.
