Different people may use the identical recipe for molded desserts, all of their molded desserts could turn out differently because of different measuring and mixing techniques. The following section presents some important measuring equivalents, tables and conversions.

Measuring Ingredients Correctly
Accurate techniques in measuring are as important as the tools for measuring. Therefore, always observe the following procedures:
- Rice and flour. Fill the cup to overflowing, level-off with a spatula or with a straight edged knife
- Sifted flour. Most cake recipes call for sifted flour. In this case, sift flour 2 or 3 times. Spoon into the cup overflowing, level off with a spatula.
- Refined sugar. Sift sugar once to take out lumps, if any. Spoon into cup and level off with a spatula. Do not pack or tap the sugar down.
- Brown sugar. Pack into cup just enough to hold its shape when turned out off cup. Level off with a spatula before emptying.
- Level a measuring spoon with straight edge of a knife to measure small amounts of salt, pepper, leavening agents or solid fats.
- Liquid ingredients. liquid measuring cup -- a glass or plastic cup with graduated markings on the side. Place the cup on a flat, level surface. Hold the cup firmly and pour the desired amount or liquid into the cup.Lean over and view the liquid at eye level to make sure it is the proper amount.
- Check and calibrate timers/thermometers, scales and other measuring devices according to manufacturer’s manual before using
- Ingredients which measure by volume and by weight demand standardized measuring tools and equipment.
- Do not shake the dry measuring cup to level off dry ingredients.
- It is easier to weigh fat, butter, margarine if bought in pre-measured sticks. If fat does not come in pre measured sticks, use a scale to weigh the needed amount.
- Liquids should be poured into cup in desired level. Cup should stand on a flat surface.
- Spring scales should be adjusted so that pointer is at zero (0). Place pan, bowl, or piece of waxed paper on scale to hold ingredient to be measured.
- When using balance scales, place the pan on the left-hand side of the balance and the pan weight on the right-hand side. Add the required weights to the right-hand side and adjust the beam on the bar so that the total is the weight needed.
- Ranges, sometimes called stoves, provide heat for cooking on top and in the oven. The controls for range heat must be accurate and easy to operate. Tools and utensils needed for cooking on the range and work space should be within easy reach.
- Learn to match the size of pan to the size of the unit and to select the right amount of heat for the cooking job to be done.
- In microwave cooking, time schedules must be followed exactly because every second is important. The microwaves shut off automatically when the door is opened.
- Refrigerators are operated by electricity. The unit that does the cooling is underneath the box behind the grill.
- Dishwashers are a great help if food is rinsed from dishes before stacking them. Follow the plan for stacking as suggested in the direction by manufacturer’s manual.
- Mixers are the most useful machines in commercial kitchens and even at home. It is good for making salad dressings, sandwich fillings, for sauces, mashing potatoes, beat batter and eggs. Attachments are also available to chop, whip, squeeze out juice, and make purees.
- Coffee makers mostly are automatic, requiring only the measurement of coffee and water.
- In preparing foods on the range or in the fryer, heat is transferred by conduction.

How many times have you been ready to cook and found you were out of a certain ingredient? Sometimes it is inconvenient to run out and purchase the necessary ingredient -- it's easier to use a similar product as a replacement. There are, however, several factors to
consider when substituting ingredients. Take into account differences in flavor, moisture, texture and weight.
Substitutions with an acid factor, such as molasses, need to be neutralized to avoid changes in the flavor and texture of the product. Differences in sweetening and thickening
power need consideration in sugar and flour substitutions. To help avoid disappointments when substituting ingredients, understand the physical and chemical properties of all ingredients. Measure accurately.
The following table gives substitutes that may be used to get a finished product similar to the
original.
The following abbreviations are used:
tsp = teaspoon
Tbsp = tablespoon
oz = ounce
lb = pound

How to Calculate Markup Percentage
Markup is the difference between how much an item costs you, and how much you
sell that item for--it's your profit per item. Any person working in business or retail will find the
skill of being able to calculate markup percentage very valuable.
Instructions
1. Calculate your peso markup. This is done by subtracting your buying price from your selling price.Example
Selling price 15.00
Purchase cost/buying price - 10.00
Peso markup 5.00
2. Decide whether you want to calculate your percentage markup based on cost or selling price. Once you choose which you will be using to calculate, it is important you stick to the method you choose throughout all your calculations, or you will end up with faulty data. If you decide to calculate your percent markup based on cost, go on to Step 3. If you decide to calculate your percent markup based on selling price, go on to Step 4.
3. Calculate percent markup based on cost. This is done by dividing the peso markup by the cost.
Example
Peso markup 5.00
Purchase cost/buying price ÷10.00
Percentage mark up .5 or 50%
4. Calculate your percent markup based on selling price. This is done by dividing the peso markup by the selling price.
Example
Peso markup 5.00
Selling price ÷15.00
Percentage mark up .33 or 33%
5. Make sure you consistently use either cost of the product or selling price to find the percent markup on an item. Even though the cost, selling price, and peso markup will always be the same, the percentage markup will be drastically different depending on if you calculate it using selling price or cost. Using selling price will give you a lower percentage markup (assuming you are making a profit), while using cost will give you a higher percentage markup.
