2203.2 Culinary Measurements

Common Units of Measurement

Volume Measurements

Volume measurements are typically used for both liquid and dry ingredients, although they are more accurate for liquids.

  • Teaspoons (tsp): Used for measuring small amounts of ingredients like spices, baking powder, or baking soda.
  • Tablespoons (tbsp): Common for larger amounts of ingredients that are still relatively small, such as oil, butter, or sugar.
  • Cups: Widely used in cooking and baking, especially in recipes from the United States. One cup is equivalent to 16 tablespoons or 8 fluid ounces.
  • Fluid Ounces (fl oz): Primarily used in the U.S. to measure liquids. Not to be confused with weight ounces.
  • Milliliters (ml) and Liters (L): Used around the world in the metric system; particularly common in countries outside of the United States.

Weight Measurements

Weight measurements are the most accurate way to measure ingredients, crucial for professional baking and cooking where precision is key.

  • Grams (g): The metric unit of measurement for small quantities of ingredients. Most kitchen scales will measure in grams.
  • Kilograms (kg): Used for larger quantities in the metric system. One kilogram equals 1000 grams.
  • Ounces (oz): Used in the imperial system for small quantities. There are 16 ounces in a pound.
  • Pounds (lb): Common in the United States for measuring larger quantities of bulk ingredients like flour or meat.

Temperature

Temperature measurements are essential for cooking and baking, ensuring that foods are cooked safely and to desired doneness.

  • Celsius (°C): Commonly used around the world, Celsius is the standard unit in the metric system for measuring temperature.
  • Fahrenheit (°F): Used primarily in the United States for ovens, stovetops, and food thermometers.

Length (Less Common in Cooking)

Length measurements are less commonly used in cooking but can be important for certain types of food preparation.

  • Inches (in): Often used in the U.S. for measuring the thickness of cuts of meat or the diameter of a pan.
  • Centimeters (cm): Used in the metric system for similar purposes as inches, such as measuring the size of baking dishes or the thickness of ingredients.

Measurement Tools

Measuring Spoons

  • Use: Measuring spoons are ideal for measuring smaller quantities of both dry and liquid ingredients, such as spices, leavening agents, extracts, and oils.
  • Sizes: Typically come in a set that includes 1/4 teaspoon, 1/2 teaspoon, 1 teaspoon, and 1 tablespoon. Some sets also include measurements like 1/8 teaspoon.

Measuring Cups

Measuring cups come in two primary types: one for dry ingredients and another for liquids. It’s important to use the correct type for each kind of ingredient to ensure accuracy.

Sizes:

  • Standard Sizes for Dry Measuring Cups: Commonly come in sets that include 1/4 cup, 1/3 cup, 1/2 cup, and 1 cup.
  • Standard Sizes for Liquid Measuring Cups: Usually available in 1 cup, 2 cups, 4 cups, and sometimes larger sizes like 8 cups.

Use for Dry Ingredients:

  • Dry measuring cups are designed to be filled to the top and then leveled off with a straight edge. This allows for precise measurements of ingredients like flour, sugar, and grains.
  • Scoop the ingredient into the cup and level the top with a knife or a flat edge to ensure an accurate measurement.

Use for Liquid Ingredients:

  • Liquid measuring cups are typically made of clear glass or plastic with a pouring spout and measurement markings up the side.
  • Pour the liquid into the cup and check the measurement at eye level to ensure accuracy. The spout helps in pouring liquids without spillage.

Kitchen Scales

Importance: Kitchen scales are crucial for achieving precise measurements, particularly in baking where the exact ratio of ingredients can affect the outcome of recipes.

Types:

  1. Digital Scales: Offer precise measurements and can easily switch between different units of measurement (grams, ounces, pounds). They usually have a tare function, which allows you to subtract the weight of the container and measure the contents only.
  2. Mechanical Scales: These are less common but still used in some kitchens. They use a spring mechanism to measure weight and typically do not have the ability to switch between units or tare weights.

Use:

  • Weighing Ingredients: More accurate than measuring by volume, weighing ingredients ensures consistency, especially important in baking recipes like bread, pastries, and delicate desserts.
  • Portion Control: Useful in both household and professional settings for maintaining portion sizes, which is crucial for dietary control and restaurant cost management.

Oven Thermometer – Use and Placement

Use:

  • An oven thermometer measures the temperature inside your oven. It’s essential because most ovens are not perfectly calibrated and the dial setting might not reflect the actual internal temperature. Using an oven thermometer helps ensure that your oven is at the correct temperature for baking or roasting.

Placement:

  • Place the oven thermometer in the center of the oven or near where the food will be cooked for the most accurate reading. Avoid placing it too close to the oven walls, heating elements, or the oven floor as these areas might give misleading readings.

Instant-Read Thermometer – Use and Placement

Use:

  • Instant-read thermometers provide a quick temperature readout and are ideal for cooking meats, poultry, and casseroles. They are not meant to stay in the food while it cooks but are instead used to check the temperature toward the end of the cooking time.

Placement:

  • Insert the thermometer probe into the thickest part of the food, avoiding bone, fat, and gristle which can give inaccurate readings. For liquids like soups or sauces, submerge the probe sufficiently to get a stable reading.

Candy/Fry Thermometer – Use and Placement

Use:

  • Candy and deep-fry thermometers are designed to withstand higher temperatures and are used for monitoring sugar syrups and hot oils. Accuracy is critical in candy making to achieve the right consistency and in deep frying to ensure the oil is hot enough for safe cooking without being so hot as to become hazardous.

Placement:

  • Clip the thermometer to the side of the pot, ensuring the tip is submerged in the liquid but not touching the bottom of the pot. This placement gives an accurate measure of the syrup or oil’s temperature.

Graduated Cylinders and Pipettes

Use:

  • Graduated cylinders and pipettes are less common in typical kitchens but are invaluable in molecular gastronomy and very precise culinary applications, such as baking where exact amounts of liquids need to be measured.
  • Graduated cylinders are used to measure and transfer liquid volumes with high accuracy. Pipettes can be used for adding very small quantities of an ingredient, such as acids or extracts, that need to be measured with precision.

Placement:

  • Graduated Cylinders: Place on a flat surface and pour the liquid into the cylinder to the desired level. Read the measurement at eye level to ensure accuracy.
  • Pipettes: Squeeze the bulb, insert the tip into the liquid, release the bulb to draw liquid up into the pipette, then dispense by squeezing the bulb again. Precision can be critical, especially in recipes requiring chemical accuracy.

Tips for Accurate Measurements

  • Use the Right Tools

    Using the correct tools for measuring ingredients is foundational to culinary accuracy. Ensure you have a variety of measuring tools on hand, including:

    • Measuring Spoons and Cups: Select a set of measuring spoons and cups for dry ingredients that come in standard sizes (e.g., 1 cup, 1/2 cup, 1/3 cup, 1/4 cup, 1 tablespoon, 1 teaspoon). These are especially useful for small quantities of both dry and wet ingredients.
    • Liquid Measuring Cups: Use these for measuring liquids. They are usually made of glass or clear plastic with measurements marked on the side.
    • Digital Kitchen Scale: A scale is essential for precise ingredient measurement, especially in baking. It allows for accurate measurement of ingredients by weight, which is often more reliable than volume measurements.

    Measure Dry Ingredients Correctly

    • Spoon and Level: When measuring flour, sugar, or baking powder, spoon the ingredients into the measuring cup and level it off with a straight edge. This technique prevents the ingredient from being packed down.
    • Sift if Needed: Before measuring ingredients like powdered sugar or cocoa powder, sift them to break up any lumps. This ensures a more accurate and consistent measurement.
    • Weigh for Precision: Using a digital kitchen scale can enhance precision, especially in baking. Weigh your ingredients for recipes that require precise ratios.

    Measure Liquid Ingredients Properly

    • Use the Right Cup: Always measure liquids in a liquid measuring cup. The clear markings and spout make it easier to measure and pour without spills.
    • Check at Eye Level: To avoid over or under-measuring, place the liquid measuring cup on a flat surface and check the level at eye level.
    • Reduce Stickiness: When measuring sticky liquids like honey or syrup, lightly coat the measuring cup with oil or use a non-stick spray. This makes the liquid slide out easily, ensuring you get the full measure.

    Follow Best Practices

    • Check Your Tools: Regularly check your measuring tools for accuracy. Measuring cups and spoons can get bent or misshapen, which may affect their accuracy.
    • Maintain Cleanliness: Always make sure your measuring tools are clean and completely dry before using them. Residue or moisture can affect the accuracy of your next measurement.
    • Calibrate Your Scale: If you use a digital scale, calibrate it according to the manufacturer’s instructions to ensure it provides accurate readings.

    Understand Recipe Requirements

    • Know When Precision is Crucial: In recipes like pastries and bread, small deviations can lead to significant changes in texture or density. In these cases, weighing ingredients is more reliable than measuring by volume.
    • Temperature of Ingredients: Some recipes specify the temperature of ingredients (e.g., room temperature butter), which can affect the outcome. Ensure your ingredients are prepped as directed.

    Conversion and Adaptation

    • Keep a Conversion Chart Handy: Have a conversion chart accessible in your kitchen for quick reference, especially when adapting recipes from different culinary systems (metric to imperial, etc.).
    • Adapt with Caution: When converting recipes, consider the properties of ingredients. For example, a cup of sifted flour weighs less than a cup of unsifted flour due to air volume.
