ifference between Mozzarella and Cheddar cheese

Mozzarella cheese is served like powder while Cheddar cheese like triangle shape.

https://www.quora.com/What-is-the-difference-between-Mozzarella-and-Cheddar-cheese
The simple answer is in the way these two cheese are produced. As cheese is made by adding rennet to milk to separates the curds from the whey, then the curds are turned into cheese. The way you treat the curds makes the cheese unique and different. Both cheddar and mozzarella cheese are cut and recooked a second time but mozzarella's curds are pressed, pulled and stretched to create it texture and is meant to be served fresh, not aged. Cheddar or cheddaring is the process of draining, stacking, and pressing the curds to achieve its unique flavor. It is name for a village in Somerset England where it was first produced. It is often aged or smoked and is most often off white or yellow, it may also appear orange do to the addition of annatto for its coloring and flavor traits. Basically cheddar is a crumbly cheese and mozzarella is a stringy cheese. But they are not regulated so they can be extremely different depending on who produces them.

Mozzarella cheese is fresh cheese that has just been made from curdling milk and separating the curd from the whey.  The cheese curds are then pressed, pulled and stretched with saltwater to produce a fresh, delicious mozzarella.  Cheddar cheese (along with many other types of cheese) is cheese that has been aged.  Depending on the aging process, the cheese gains certain flavors and takes on certain properties once it has been treated and allowed to sit.  Some cheeses simply sit in the open air and are allowed to mold on the outside.  Others are bandaged with wax or gauze so that the aging process is a little more controlled.  Some are made with goats milk, some with cows milk...  If you're interested in making your own cheese, you can find the simple process for making mozzarella with a quick google search.  The same can be said about other types of cheese like Brie and Colby Jack.

cold coffee, float, milk shakes, mojita,iced lemon tea - what do they mean?

https://en.wikipedia.org/wiki/Iced_coffee
Iced coffee is a type of coffee served cold, brewed various brewing methods, with the fundamental division being cold brew – brewing the coffee cold, yielding different flavor, but not requiring cooling – or brewing hot and then cooling, generally by simply pouring over ice or into ice cold milk. In case of hot brewing this can be normally brewed coffee (drip, press pot, etc.), or espresso. Also in hot brewing, sweeteners and flavorings are often mixed into the hot coffee before cooling, due to faster dissolution in hot water. Alternatively, syrup (sugar pre-dissolved in water) may be used, particularly gum syrup.
Regardless of brewing method, iced coffee is generally brewed at a higher strength than normal coffee, due to the dilution caused by the ice. In Greece, it may be called Frappe.

@Cold brew means brewing in normal temperature or cold without using hot water. /@ https://en.wikipedia.org/wiki/List_of_coffee_drinks#Cold_brewBecause the ground coffee beans in cold-brewed coffee never come into contact with heated water, the process of leaching flavor from the beans produces a chemical profile different from conventional brewing methods.[10][11] Coffee beans contain a number of constituent parts that are more soluble at higher temperatures, such as caffeine, oils and fatty acids. Brewing at a lower temperature results in lower acidity and lower caffeine content when brewed in equal volume.[12][13] It is around 65 to 70 percent less acidic than hot drip coffee or espresso, per part.[10]


India>>Iced coffee in India usually consists of instant coffee mixed with cold/frozen milk in a blender, producing a thin, coffee-flavored smoothie or often mixed with vanilla ice cream for thicker consistency.
