Answer the following question: Information: - Common chicory, "Cichorium intybus", is a somewhat woody, perennial herbaceous plant of the dandelion family Asteraceae, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. "sativum"), which are baked, ground, and used as a coffee substitute and additive. It is also grown as a forage crop for livestock. It lives as a wild plant on roadsides in its native Europe, and is now common in North America, China, and Australia, where it has become widely naturalized. "Chicory" is also the common name in the United States for curly endive ("Cichorium endivia"); these two closely related species are often confused. - The yolk is the portion of an egg with the primary function to supply food for the development of the animal embryo. Some kinds of eggs contain no yolk, for example because they are laid in situations where the food supply is adequate (such as in the body of the host of a parasitoid) or because the embryo develops in the parent's body, which supplies the food, sometimes through a placenta. Reproductive systems in which the mother's body supplies the embryo directly are said to be matrotrophic; those in which the embryo is supplied by yolk are said to be lecithotrophic. In many species, such as all birds, and most reptiles and insects, the yolk takes the form of a special storage organ constructed in the reproductive tract of the mother. In many other animals, especially very small species such as some fishes and invertebrates, the yolk material is not in a special organ, but inside the ovum. - Hollandaise sauce is an emulsion of egg yolk and liquid butter, usually seasoned with lemon juice, salt, and a little white pepper or cayenne pepper. In appearance, it is light yellow and opaque, smooth and creamy. The flavor is rich and buttery, with a mild tang added by an acidic component such as lemon juice, yet not so strong as to overpower mildly flavored foods. - Mayonnaise (or in AmE also , and often abbreviated as mayo ) is a thick, creamy dressing often used as a condiment. It is a stable emulsion of oil, egg yolk, and either vinegar or lemon juice, with many options for embellishment with other herbs and spices. Proteins and lecithin in the egg yolk serve as emulsifiers in both mayonnaise and hollandaise sauce. Commercial egg-free alternatives are available for vegans and others who want to avoid animal products and cholesterol, or who are allergic to eggs. - Lecithin (from the Greek "lekithos", "egg yolk") is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues, which are amphiphilic - they attract both water and fatty substances (and so are both hydrophilic and lipophilic), and are used for smoothing food textures, dissolving powders (emulsifying), homogenizing liquid mixtures, and repelling sticking materials. Lecithins are usually phospholipids, composed of phosphoric acid with choline, glycerol or other fatty acids usually glycolipids or triglyceride. Glycerophospholipids in lecithin include phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, and phosphatidic acid. - A condiment is a spice, sauce, or, preparation that is added to food to impart a particular flavor, to enhance its flavor, or in some cultures, to complement the dish. The term originally described pickled or preserved foods, but has shifted meaning over time. - Proteins (or ) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity. - Lettuce ("Lactuca sativa") is an annual plant of the daisy family, Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, the ", or asparagus lettuce (celtuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. World production of lettuce and chicory for calendar year 2013 was 24.9 million tonnes, over half of which came from China. - Vinegar is a liquid consisting of about 520% acetic acid (CHCOOH), water, and other trace chemicals, which may include flavorings. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria. Vinegar is now mainly used as a cooking ingredient, or in pickling. As the most easily manufactured mild acid, it has historically had a great variety of industrial, medical, and domestic uses, some of which (such as its use as a general household cleaner) are still commonly practiced today. - Asteraceae or Compositae (commonly referred to as the aster, daisy, composite, or sunflower family) is an exceedingly large and widespread family of flowering plants (Angiospermae). - The hypocotyl (short for "hypocotyledonous stem", meaning "below seed leaf") is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root). - An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals. - In everyday usage, a vegetable is any part of a plant that is consumed by humans as food as part of a savory meal. The term "vegetable" is somewhat arbitrary, and largely defined through culinary and cultural tradition. It normally excludes other food derived from plants such as fruits, nuts, and cereal grains, but includes seeds such as pulses. The original meaning of the word "vegetable", still used in biology, was to describe all types of plant, as in the terms "vegetable kingdom" and "vegetable matter". - Apiaceae or Umbelliferae, is a family of mostly aromatic flowering plants commonly known as the celery, carrot or parsley family. The family, which is named after the type genus "Apium", is large, with more than 3,700 species spread across 434 genera; it is the 16th-largest family of flowering plants. Included in this family are the well-known plants: angelica, anise, arracacha, asafoetida, caraway, carrot, celery, "Centella asiatica", chervil, cicely, coriander (cilantro), culantro, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, cow parsnip, sea holly, giant hogweed and silphium (a plant whose identity is unclear and which may be extinct). - The term cultivar is, most commonly, referring to an assemblage of plants selected for desirable characteristics that are maintained during propagation. More generally, "cultivar" refers to the most basic classification category of cultivated plants governed by the ICNCP. Most cultivars have arisen in cultivation, but a few are special selections from the wild. - Generally speaking, a calendar year begins on the New Year's Day of the given calendar system and ends on the day before the following New Year's Day, and thus consists of a whole number of days. A calendar year can also start on any other named day of the calendar, and end on the day before this named day in the following year. To reconcile the calendar year with the astronomical cycle (which has a fractional number of days) certain years contain extra days. - An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms "colloid" and "emulsion" are sometimes used interchangeably, "emulsion" should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, mayonnaise, and some cutting fluids for metal working. - An oil is any neutral, nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (immiscible with water, literally "water fearing") and lipophilic (miscible with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and surface active. - A Waldorf salad is a salad generally made of fresh apples , celery and walnuts , dressed in mayonnaise , and usually served on a bed of lettuce as an appetizer or a light meal . The salad was first created between 1893 and 1896 at the Waldorf Hotel in New York City ( the precursor of the Waldorf - Astoria Hotel , which came into being with the merger of the Waldorf with the adjacent Astoria Hotel , opened in 1897 ) . Oscar Tschirky , who was the Waldorf 's maitre d'hotel and developed or inspired many of its signature dishes , is widely credited with creating the recipe . In 1896 , Waldorf Salad appeared in The Cook Book by '' Oscar of the Waldorf '' ; the original recipe did not contain nuts , but they had been added by the time the recipe appeared in The Rector Cook Book in 1928 . Other ingredients , such as chicken , turkey , grapes , and dried fruit ( e.g. dates or raisins ) are sometimes added . Updated versions of the salad sometimes change the dressing to a seasoned mayonnaise or a yogurt dressing . A variation known as an Emerald Salad replaces celery with cauliflower . The salad also may include zest of oranges and lemons . - Lactuca, commonly known as lettuce, is a genus of flowering plants in the daisy family, Asteraceae. The genus includes at least 50 species, distributed worldwide, but mainly in temperate Eurasia. - Cholesterol, from the Ancient Greek "chole-" (bile) and "stereos" (solid) followed by the chemical suffix "-ol" for an alcohol, is an organic molecule. It is a sterol (or modified steroid), a type of lipid molecule, and is biosynthesized by all animal cells, because it is an essential structural component of all animal cell membranes; essential to maintain both membrane structural integrity and fluidity. Cholesterol enables animal cells to dispense with a cell wall (to protect membrane integrity and cell viability), thereby allowing animal cells to change shape and animals to move (unlike bacteria and plant cells, which are restricted by their cell walls). - An annual plant is a plant that completes its life cycle, from germination to the production of seed, within one year, and then dies. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. - Celery ("Apium graveolens"), a marshland plant in the family Apiaceae, has been cultivated as a vegetable since antiquity. Celery has a long fibrous stalk tapering into leaves. Depending on location and cultivar, either its stalks, leaves, or hypocotyl are eaten and used in cooking. - Leaf vegetables, also called potherbs, greens, vegetable greens, leafy greens, or salad greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Although they come from a very wide variety of plants, most share a great deal with other leaf vegetables in nutrition and cooking methods. Given the paragraphs above, decide what entity has the relation 'has part' with 'lactuca sativa'.
