How to standardise cold drink recipes: Record ratios and mixing order for easy application

Why does a cold drink recipe need to be standardised?

For cold drink shops in Vietnam, how to standardise a cold drink recipe starts with clearly recording the ingredients, quantities and procedures. A drink can change noticeably simply because the person preparing it uses a different measuring cup, adds the ice at a different point or changes the order of the ingredients. Therefore, the recipe used at the counter should not be just a list of ingredients; it is a short procedure, clear enough for several staff members to follow in the same way.

People who have just opened a shop often ask whether they should start with the proportions or the mixing order. The practical answer is to record both, then describe the finished product so that batches can be compared on a consistent basis. The aim of standardisation is not to create a recipe that remains unchanged in every situation, but to reduce unintended differences during preparation.

In counter operations and barista training, differences between recipe versions often arise from the ingredients, equipment or preparation habits. Before putting a drink on sale, the person in charge should finalise one internal version, clearly record the preparation method and change only one factor in each trial.

1. Identify the role of each component

Make a list of ingredients by function rather than from memory. For cold drinks, the components can be grouped into base ingredients, main flavour ingredients, sweetening or intensity-enhancing ingredients, adjusting liquids, ice and finishing elements.

Group to record	Checking question
Base ingredient	How does it create body, creaminess or texture in the drink?
Main flavour ingredient	Is this the flavour that the drinker should recognise first?
Adjusting ingredient	How does it change the sweetness, acidity, dilution or intensity?
Ice and finishing elements	Is the ice weighed, measured or added by volume? Does the finishing element affect the quantity?

This grouping method helps identify missing information in a recipe. For example, writing “add enough ice” does not indicate the final volume, while “stir until combined” does not describe when to stop.

If the drink uses cream or a Gelato base, record the product name, weight and method of adding it to the glass separately. You can also refer to Preparation Guide and see Gelato Baby Boss Products to standardise the names of ingredients in internal documents.

2. Record quantities using a single system

Choose one main unit for each group and use it consistently throughout the recipe sheet. Weight is usually easier to check when a batch needs to be repeated, while volume may be more convenient for work at the counter; the important thing is not to use grams in one part of the same recipe and “one scoop” or “a little” in another.

What should a recipe sheet include?

• The drink name and applicable glass size.
• The weight or volume of each component.
• The temperature or condition of the ingredients at the time of use, if this factor affects the procedure.
• The weight of the ice or a clearly defined method for measuring it.
• The expected finished volume and a brief description of the colour, thickness and flavour.
• The trial date, person responsible and recipe version code.

Do not record a single ratio and then apply it to every glass size if the amount of ice, base or finishing element changes. Create a separate conversion table for each size, then check it again with a small batch rather than simply multiplying the figures by feel.

For ingredients supplied in packets or base products, record the exact product name and specification being used. When changing to another product, even if it is intended for the same use, create a new trial version to avoid confusion.

3. Fix the preparation order and stopping point

The preparation order should be written using specific verbs: weigh, measure, add, stir, blend, shake, pour or finish. Avoid instructions such as “do it as usual”, because new staff do not share the same procedural memory as experienced colleagues.

1. Prepare and check all components against the recipe sheet.
2. Measure each component using the specified unit.
3. Add the ingredients in the agreed order, clearly recording which component goes in first and which goes in afterwards.
4. Mix, shake or blend for the specified length of time or until reaching the described condition.
5. Add the ice or finishing element according to the drink's procedure.
6. Compare the finished product with the standard description before serving.

The list above is a recording framework, not a recipe for a specific drink. The preparation time, amount of ice and equipment should be filled in after the shop has trialled the drink using its actual ingredients and equipment.

If using a blender or shaker, clearly record the equipment type and any relevant operating conditions. A recipe tested with one piece of equipment may produce different results when transferred to another, so equipment changes should also be recorded in the version history.

4. Check each batch using a comparison table

After each trial, do not just write “good” or “not up to standard”. Assess it using describable criteria, such as consistency, thickness, flavour intensity, the extent to which the ice has melted and the volume after finishing.

Criterion	How to record	Action when it differs
Quantity	Which component was weighed or measured differently from the recipe sheet?	Correct the measuring method or revise the sheet; do not change several factors at the same time.
Preparation order	Were any steps skipped or moved to a different position?	Rewrite the step using a verb and place it somewhere easy to see.
Status	Is the drink uniform, too thin, too thick or separated?	Recheck the proportions, mixing process and when the ice was added.
Sensory evaluation	Are the main flavour, sweetness and chill level consistent with the standard description?	Adjust only one ingredient in the next trial.

It states that water, ingredients, additives and semi-finished products should be checked before preparation; when applied to record-keeping, this is only a suggestion for checking before starting the process, not a basis for concluding anything about the safety or shelf life of drinks.

5. An easy-to-use recipe form template

You can start with one page for each item. The shorter the form, the easier it is for staff to use at the counter; longer explanatory notes should be placed in separate training materials.

• Item name: record the internal name and cup size.
• Version code: record the date or change identifier.
• Ingredients: record the name, weight or volume of each ingredient.
• Equipment: record the tools required.
• Preparation order: write it as short steps that can be ticked off after completion.
• Finished product standard: describe the colour, consistency, aroma and flavour, fill level and finishing touches.
• Trial batch notes: record deviations, suspected causes and changes for the next trial.

A version should only be approved once another preparer can read the form and carry it out without needing to ask for basic information again. Once the recipe is stable, keep one copy for use at the counter and another with a revision history, making it easier to trace the cause when quality changes.

If you are developing a menu with several cold items, this systematisation can be combined with Gelato knowledge or Gelato ice cream setup consultation, depending on the café's operating model.

Common mistakes when standardising

Recording by feel

Words such as “just enough”, “a little” or “until ready” only have meaning for people who are familiar with the item. Replace them with quantities, times, number of actions or descriptions of states that can be checked.

Changing several factors in one trial

If you change the base, the amount of ice and the preparation order at the same time, it will be difficult to know which factor caused the difference. Each trial round should have one main change, with clear notes.

Forgetting to record the cup size and equipment

The same item name may require a different preparation method when the cup size or machine is different. The recipe form should place these two pieces of information at the top to prevent incorrect application.

Not updating the version

When ingredients or equipment change, create a new version code instead of making an unrecorded edit to the old version. This helps staff know which document they are using and helps the person in charge trace the item trial process.

Conclusion and starting steps

To standardise a cold drink recipe, start with an item currently being sold, record all ingredients using the same unit system, fix the preparation order and describe the finished product. Then trial it with another preparer, compare each criterion and change only one factor in each trial round.

A good recipe form should enable someone else to prepare the item correctly without having to guess. When you need to develop the product range further, you can explore Gelato Pro ice cream or get in touch via the Contact page to choose an approach that suits the café's operating model.
