Buttermilk is a tangy, dairy-based liquid often used in cooking and baking. It’s traditionally a byproduct of churning butter, but modern buttermilk is typically made by adding lactic acid bacteria to low-fat milk. This bacterial fermentation imparts its characteristic sour flavor and thickens the milk.
Buttermilk provides a pleasant acidity and moisture to recipes, especially in pancakes, biscuits, and marinades. It also aids in leavening, making baked goods rise. Additionally, buttermilk can be enjoyed as a refreshing drink on its own or blended with other ingredients for beverages and dressings, lending a delightful, tart quality.

There is no single international standard for buttermilk, as its composition and characteristics can vary from one region to another.
ISO standards help ensure the quality, safety, and consistency of these products in international trade. Some ISO standards related to milk and dairy products include:
ISO 7886-1:2005 – Milk and milk products — Determination of the protein content — Part 1: Test at 0.020 specific density (Reference method)
ISO 1053:2006 – Milk — Enumeration of somatic cells
ISO 21415-1:2006 – Milk — Enumeration of psychrotrophic microorganisms — Part 1: Colony-count technique at 6.5 degrees C
ISO 11816-1:2013 – Milk — Determination of milkfat, protein, and lactose content — Part 1: Guidance on the operation of mid-infrared instruments
These standards cover various aspects of milk quality, testing methods, and safety parameters. Dairy products, including milk, undergo strict quality control and testing to ensure they meet the required standards for international trade and consumer safety.

Dogs have been bred for a variety of purposes throughout history, including as working animals to support agriculture. Dogs have been bred for specific traits that make them well-suited to work on farms, such as intelligence, obedience, strength, and endurance*.
* Here are a few examples of how dogs were bred to support agriculture:
Herding dogs: Dogs such as the Border Collie, Australian Cattle Dog, and German Shepherd were bred to help farmers manage livestock by herding them from one place to another. These dogs have a natural instinct to gather and control herds of animals, and they can be trained to respond to a farmer’s commands.
Hunting dogs: Many breeds of dogs, such as the Labrador Retriever, were originally bred as hunting dogs to assist farmers with hunting game for food. These dogs have a keen sense of smell and are skilled at tracking and retrieving prey.
Guard dogs:Certain breeds of dogs, such as the Great Pyrenees, were bred to protect livestock from predators such as wolves and bears. These dogs are fiercely protective of their flock and will guard them from any perceived threat.
Draft dogs: Some large breeds of dogs, such as the Bernese Mountain Dog and the Saint Bernard, were bred to pull carts and wagons on farms. These dogs are strong and muscular and can move heavy loads across long distances.
Overall, dogs have been bred for centuries to support agriculture in a variety of ways. Their intelligence, loyalty, and hardworking nature have made them invaluable assets to farmers and have helped to shape the course of human history.
The history of scones is believed to have originated in Scotland. The name “scone” is said to come from the Dutch word “schoonbrot,” which means “beautiful bread.” Scones have a long and interesting history that dates back several centuries.
Originally, scones were not the sweet, buttery treats we know today. Instead, they were simple unleavened oatcakes or griddle cakes made from barley, oats, or wheat. These early scones were baked on griddles or stovetops rather than being oven-baked.
As time went on, the recipe for scones evolved, and they became more commonly associated with Scotland and England. The Scottish version of scones was typically round and made with oats. They were cooked on a griddle or in a pan and then cut into triangular sections, which were known as “bannocks.” These bannocks were the ancestors of the modern scone.
In the 19th century, with the advent of baking powder and modern ovens, scones began to be baked instead of griddle-cooked. The addition of baking powder allowed scones to rise and become lighter and fluffier. The ingredients were refined to include flour, butter, milk or cream, and a leavening agent like baking powder. This marked the shift from the traditional oat-based scone to the more recognizable wheat-based scone we know today.
Scones’ popularity spread beyond Scotland and England, and they became a common teatime treat across the United Kingdom and other English-speaking countries. The addition of raisins, currants, or other dried fruits, as well as sugar, transformed scones into the sweet delicacies that are commonly enjoyed today, often served with clotted cream and jam in the classic English afternoon tea.
In the United States, scones have also become popular, with various regional and cultural variations. American scones may be larger, sweeter, and have a wider variety of flavor options, such as blueberry, cranberry-orange, or chocolate chip. Today, scones continue to be beloved treats enjoyed for breakfast, brunch, afternoon tea, or as a delightful snack with a cup of tea or coffee. Their history reflects centuries of evolution and cultural influence, making them a delightful and enduring part of baking traditions worldwide.
The standard scone is a simple and versatile preparation that can be customized with various additions, such as dried fruits, nuts, or chocolate chips, to suit different tastes.
Here is a basic recipe for making standard scones:
Ingredients:
2 cups all-purpose flour
1/4 cup granulated sugar
1 tablespoon baking powder
1/2 teaspoon salt
1/2 cup cold unsalted butter, cut into small cubes
1/2 cup milk (plus more for brushing on top)
1 large egg
Optional: 1 teaspoon vanilla extract or other flavorings (e.g., almond extract, lemon zest)
Optional: Additions such as dried fruits, chocolate chips, or nuts (about 1/2 cup)
Instructions:
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
Add the cold butter cubes to the flour mixture and use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs. The butter should be well distributed but still in small pieces.
If you’re adding any optional flavorings or additions, mix them into the dry ingredients at this stage.
In a separate small bowl, whisk together the milk, egg, and optional vanilla extract (or other flavorings) until well combined.
Create a well in the center of the dry ingredients and pour the wet mixture into it. Gently stir the ingredients together until just combined. Be careful not to overmix; the dough should be slightly crumbly but hold together.
Transfer the dough onto a lightly floured surface and shape it into a round disk, about 1 inch (2.5 cm) thick.
Use a sharp knife or a biscuit cutter to cut the dough into wedges or rounds, depending on your preference. Traditionally, scones are cut into triangular shapes.
Place the scones on the prepared baking sheet, leaving some space between them.
Brush the tops of the scones with a little milk to give them a nice golden color when baked.
Bake the scones in the preheated oven for about 15-20 minutes or until they are lightly golden on top.
Remove from the oven and let them cool slightly before serving. Scones are best enjoyed fresh and can be served with butter, clotted cream, jam, or any other toppings of your choice.
This standard scone recipe provides a classic and delicious base that you can experiment with by adding various flavors and mix-ins to create your own unique variations.
In most jurisdictions the standard of care for operation and maintenance of education facilities is discovered and promulgated by a “fabric” of consensus products developed by a kind of “shadow government” created by a network of non-profit publishers; among them the International Code Council. The ICC has one of the most dynamic catalogs in the construction industry and today we drill into the the International Property Maintenance Code which completed another revision cycle in 2021. Operation and maintenance of education facilities is the (much larger) part of #TotalCostofOwnership of the real assets of a school district, college or university. Public access to most recent revision to the IPMC is linked below:
Note the concern for swimming pools, radon, light, ventilation and occupancy limits.
The ICC Group A tranche of titles will undergo another cyclic revision starting in 2023. Since so much of the ICC catalog underlies occupancy safety for education, healthcare and nearly all other aspects of the built environment we track the action on a near-daily basis. You may join any of our daily colloquia, shown on our CALENDAR, or interact directly with the ICC with the link below:
The ICC catalog is regarded as the most authoritative for education facility management. We maintain the IPMC on the standing agenda of our Hammurabi and Interiors colloquia. See our CALENDAR for the next colloquium; open to everyone.
