Study Notes
Vegetable Preparation
- Proper preparation of ingredients reduces cooking time, streamlines operations, and upholds sanitary standards, preventing foodborne illnesses and ensuring efficiency and safety in the culinary process.
- In professional kitchens, thorough vegetable preparation is required, including washing, peeling, and cutting.
- Washing involves rinsing vegetables in cold water to remove dirt and debris, with special care taken for root vegetables like potatoes, which require intense scrubbing.
- Leafy greens require multiple cold water rinses to remove dirt, and suitable drainage is critical to prevent rotting.
Soaking
- Extended soaking of vegetables is generally prohibited due to flavour and nutritional loss, with a few exceptions like cabbage, broccoli, and cauliflower, which benefit from a brief 30-minute soak in cold salted water.
- Brief soaking of limp vegetables in cold water can help restore crispness, while soaking dried legumes is necessary to replenish moisture lost during the drying process.
Peeling and Cutting
- When preparing fruits and vegetables, aim for a thin peel to keep nutrients beneath the surface, and ensure uniform cutting for even cooking.
- Peel and cut vegetables shortly before cooking to avoid drying and vitamin loss from oxidation.
- Prevent browning in easily oxidizable vegetables like potatoes and eggplant by employing acid or antioxidant solutions, or soak them in water until ready to use.
Classifying Vegetables
- From a botanical perspective, many fruits are mistakenly referred to as vegetables, such as tomatoes, which are technically fruits.
- A fruit is the ripening ovary or ovaries of a seed-bearing plant, which contains the seeds.
- Vegetables can be classified into categories like roots, tubers, and fruits, but this classification is not always useful in a culinary context.
Cooking
- Using precise techniques for preparing canned vegetables gives optimal outcomes, including wiping the can's top before opening and using a clean can opener to maintain hygiene.
- When draining vegetables, save half of the liquid for boiling to shorten subsequent cooking times.
- Canned vegetables require warming rather than boiling, and following health regulations, keep the temperature at 88°C for at least 10 minutes to reduce the risk of botulism.
Handling Dried Vegetables
- There are two basic kinds of dried vegetables, and proper storage procedures help to optimize kitchen operations, reduce waste, and maintain culinary standards.
Fresh Vegetables
- Correctly storing fresh vegetables in a commercial kitchen is vital for quality and efficiency, with each vegetable having unique specifications for temperature and humidity requirements.
- Potatoes, onions, and winter squash are stored at cool temperatures (50-65°F/10-18°C) in a dry, dark place.
- Other vegetables must be refrigerated, and peeled and cut vegetables need extra protection from drying and oxidation.
Frozen Vegetables
- In a commercial kitchen, proper storage of frozen vegetables is crucial for quality and efficiency, with adherence to specific temperature and packaging requirements for each vegetable.
- Store frozen vegetables at 0°F (-18°C) or colder, in original containers, until ready for use.
Dried Vegetables
- In a commercial kitchen, precise storage of dried vegetables is critical for longevity and culinary quality, with adherence to specific guidelines, such as maintaining airtight containers and ideal temperature conditions.
- Store dried vegetables in a cool (less than 75°F/24°C), dry, well-ventilated place, and keep them well sealed and off the floor.
Canned Vegetables
- Store canned vegetables in a cool, dry place, away from sunlight and off the floor, and discard cans that show signs of damage or spoilage.
Leftovers
- The best way to store leftovers is not to create them in the first place, and careful planning and small-batch cooking reduce leftovers.
- Store leftover creamed vegetables for one day only, and then either use or discard.
Learn the importance of proper vegetable preparation in professional kitchens, including washing, peeling, and cutting to ensure efficiency, safety, and quality.
