What ingredient of Yumil-gwa, in a botanical context, implies that the shell is indehiscent?
nut
Yumil-gwa
Yumil-gwa (유밀과 ; 油蜜菓 ) is a variety of "hangwa" (a traditional Korean confection).
 Different varieties of "yumil-gwa" can be made by combining a wheat flour dough with various ingredients.
 Ingredients that are typically added can include: honey, cooking oil, cinnamon powder, nuts, ginger juice, jujube, and "cheongju" (rice wine).
Nut (fruit)
A nut is a fruit composed of an inedible hard shell and a seed, which is generally edible.
 In general usage, a wide variety of dried seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent).
 The translation of "nut" in certain languages frequently requires paraphrases, as the word is ambiguous.
Recontextualisation
Recontextualisation is a process that extracts text, signs or meaning from its original context (decontextualisation) in order to introduce it into another context.
 Since the meaning of texts and signs depend on their context, recontextualisation implies a change of meaning, and often of the communicative purpose too.
 The linguist Per Linell defines recontextualisation as: Shell and tube heat exchanger
A shell and tube heat exchanger is a class of heat exchanger designs.
 It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications.
 As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it.
 One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids.
 The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc. Ernst Heinrich Friedrich Meyer
Ernst Heinrich Friedrich Meyer (1 January 1791 Hanover, Brunswick-Lüneburg – 7 August 1858 Königsberg, East Prussia) was a German botanist and botanical historian.
 Born in Hanover, he lectured in Göttingen and in 1826 became a professor of botany at the University of Königsberg, as well as Director of the Botanical Garden.
 His botanical specialty was the Juncaceae, or family of rushes.
 His major work was the four-volume "Geschichte der Botanik" (“History of Botany,” 1854–57).
 His history covered ancient authorities such as Aristotle and Theophrastus, explored the beginnings of modern botany in the context of 15th- and 16th-century intellectual practice, and offered a wealth of biographical data on early modern botanists.
 Julius von Sachs pronounced him “no great botanist” but admitted that he “possessed a clever and cultivated intellect.” Sinecatechins
Sinecatechins (USAN, trade names Veregen and Polyphenon E) is a specific water extract of green tea leaves from "Camellia sinensis" that is the active ingredient in an ointment approved by the FDA in 2006 as a botanical drug to treat genital warts.
 Sinecatechins are mostly catechins, 55% of which is epigallocatechin gallate.
 It was the first botanical drug approved by the US FDA. Calendar (archives)
A calendar (sometimes historically spelled kalendar) is, in the context of archival science, textual scholarship, and archival publication, a descriptive list of documents.
 The verb "to calendar" means to compile or edit such a list.
 The word is used differently in Britain and North America with regard to the amount of detail expected: in Britain, it implies a detailed summary which can be used as a substitute for the full text; whereas in North America it implies a more basic inventory. Culm (botany)
Culm, in botanical context, originally referred to a stem of any type of plant.
 It is derived from the Latin word for "stalk" ("culmus") and now specifically refers to the above-ground or aerial stems of grasses and sedges. Drupe
In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin; and mesocarp, or flesh) surrounds a single shell (the pit, stone, or pyrene) of hardened endocarp with a seed (kernel) inside.
 These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions).
 The definitive characteristic of a drupe is that the hard, "lignified" stone (or pit) is derived from the ovary wall of the flower—in an aggregate fruit composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet and may together form a botanic berry. Indian Mound Park (Dauphin Island, Alabama)
Indian Mound Park, also known as Shell Mound Park or Indian Shell Mound Park, is a park and bird refuge located on the northern shore of Dauphin Island, a barrier island of Mobile County, Alabama in the United States.
 In addition to the many birds which visit, a wide variety of botanical species contribute to the natural offerings.
 The site is historically significant due to the presence of prehistoric Indian shell middens, mounds composed of discarded oyster shells.
 The park was added to the National Register of Historic Places on August 14, 1973.
 It is administered by the Alabama Department of Conservation and Natural Resources.
