Culinary Techniques

Frying potatoes approximately triples their calorie content compared to baking. A medium baked potato has about 160 calories, while the same amount as French fries has roughly 450-500 calories. This dramatic increase occurs because potatoes absorb oil during frying - oil is calorie-dense at 120 calories per tablespoon.

Paneer is made by curdling milk with an acidic substance like vinegar or lemon juice. The acid causes the milk proteins to coagulate and separate from the whey, forming solid curds. Adding cream, oil, or buttermilk will not create the curd needed for paneer.

At higher altitudes, atmospheric pressure is lower, which causes water to boil at temperatures below 100°C. Since the maximum temperature reached by boiling water is lower, food takes longer to cook. This is a real phenomenon observed in hill stations and mountains.

A pressure cooker traps steam, increasing the pressure inside. Higher pressure raises the boiling point of water above 100°C, allowing food to cook at higher temperatures and therefore faster. Option C is incorrect because pressure is high, not low. Option D is wrong because water boils at higher temperature, not lower.

Kosher refers to the set of dietary laws and food preparation methods that conform to Jewish religious requirements. It specifies which foods are permissible and how they must be prepared, processed, and consumed, covering everything from animal slaughter methods to the separation of meat and dairy products.

Roast, boil, and fry are all cooking methods that use heat. Peel is a preparation method that removes skin without applying heat.

The collective term for the range of vegetables, fruits, meats, nuts, grains, herbs and spices used in cooking is 'ingredients'. These are the raw materials combined to create dishes through various cooking methods.

According to Newton's law of cooling, heat loss rate is proportional to temperature difference. Adding cream sooner reduces the coffee's temperature earlier, creating a smaller temperature difference with surroundings and slower heat loss thereafter, resulting in hotter coffee at drinking time.

When you soak an egg in vinegar, the acetic acid reacts with the calcium carbonate in the eggshell, dissolving it over 24 hours. This leaves the egg with just the membrane, making it feel rubbery and bouncy. The yolk doesn't change color, it doesn't disintegrate, and the shell doesn't split cleanly - it gradually dissolves. This is a classic kitchen chemistry experiment.

Cooking transforms food chemically through heat-induced reactions including protein denaturation, starch gelatinization, caramelization, and the Maillard reaction. These processes change the molecular structure of food, affecting taste, texture, digestibility, and nutritional value.

Cream of tartar is the common name for potassium hydrogen tartrate (KC4H5O6), a byproduct of winemaking used in baking. It stabilizes egg whites and acts as a leavening agent. Tartare sauce is a condiment, baking soda is sodium bicarbonate, and yeast is a fungus.

Teflon (polytetrafluoroethylene or PTFE) is the standard non-stick coating used on cookware due to its high heat resistance, chemical inertness, and extremely low friction surface. PVC is used for pipes and insulation, black paint is simply a coloring agent, and polystyrene is a brittle plastic used for packaging - none of these provide non-stick properties.
