Does cooking always require heat?
Cooking or cookery is the art, technology, science and craft of preparing food for consumption with or without the use of heat.

Pressure cooking
Pressure cooking is the process of cooking food, using water or other cooking liquid, in a sealed vessel known as a "pressure cooker". Pressure is created by boiling a liquid, such as water or broth, inside the closed pressure cooker. The trapped steam increases the internal pressure and allows the temperature to rise. After use, the pressure is slowly released so that the vessel can be opened safely. Pressure cooking can be used for quick simulation of the effects of long braising. Almost any food which can be cooked in steam or water-based liquids can be cooked in a pressure cooker. In 1679, French physicist Denis Papin, better known for his studies on steam, invented the "steam digester" in an attempt to reduce the cooking time of food.
Induction cooking
Induction cooking heats a cooking vessel by magnetic induction, instead of by thermal conduction from a flame, or an electrical heating element. Because inductive heating directly heats the vessel, very rapid increases in temperature can be achieved. In an induction cooktop ("induction hob" or "induction stove"), a coil of copper wire is placed under the cooking pot and an alternating electric current is passed through it. The resulting oscillating magnetic field induces a magnetic flux which repeatedly magnetises the pot, treating it like the lossy magnetic core of a transformer. This produces large eddy currents in the pot, which because of the resistance of the pot, heats it.
Solar thermal collector
A solar thermal collector collects heat by absorbing sunlight. A collector is a device for capturing solar radiation. Solar radiation is energy in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The quantity of solar energy striking the Earth's surface (solar constant) averages about 1,000 watts per square meter under clear skies, depending upon weather conditions, location and orientation. The term "solar collector" commonly refers to solar hot water panels, but may refer to installations such as solar parabolic troughs and solar towers; or basic installations such as solar air heaters.
Epoxy
Epoxy is either any of the basic components or the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols. These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing.
Rice cooker
A rice cooker or rice steamer is an automated kitchen appliance designed to boil or steam rice. It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex rice cookers may have many more sensors and other components, and may be multipurpose. The term rice cooker formerly applied to non-automated dedicated rice-cooking utensils, which have an ancient history (a ceramic rice steamer dated to 1250 BC is on display in the British Museum). It now applies mostly to automated cookers. Electric rice cookers were developed in Japan, where they are known as pressure cookers .
Compressed air energy storage
Compressed air energy storage (CAES) is a way to store energy generated at one time for use at another time using compressed air. At utility scale, energy generated during periods of low energy demand (off-peak) can be released to meet higher demand (peak load) periods. Small scale systems have long been used in such applications as propulsion of mine locomotives. Large scale applications must conserve the heat energy associated with compressing air; dissipating heat lowers the energy efficiency of the storage system. Compression of air creates heat; the air is warmer after compression. Expansion removes heat.
Barbecue grill
A barbecue grill is a device that cooks food by applying heat from below. There are several varieties of grills, with most falling into one of two categories: gas-fueled or charcoal. There is debate over which method yields superior results. Grilling has existed in the Americas since pre-Colonial times. The Arawak people of South America roasted meat on a wooden structure called a barbacoa in Spanish. For centuries, the term "barbacoa" referred to the wooden structure and not the act of grilling, but it was eventually modified to "barbecue." It was also applied to the pit-style cooking techniques now frequently used in the Southeastern United States.

I think so. Can you think of anything that you'd call cooked without heat?
