To make Greek-style yogurt soft serve, follow these steps:

1. Add the contents of one 1.8kg bag of N715 to 4 litres of drinking water and stir well.

2. Allow the mix to rehydrate for 10 minutes.

3. Add 500g of your favourite plain tub yoghurt and stir until the mixture is smooth and fully combined.

4. Transfer the liquid mix into your soft serve machine.

5. Freeze down according to your machine’s operating instructions and serve.

This method produces a smooth, creamy Greek-style yogurt soft serve with excellent texture and flavour.

As a general guide, soft serve mix can be mixed and chilled 2–3 days in advance. This timeframe represents the total recommended period from rehydration to discard and should not be exceeded.

Pre-batching soft serve mix can help improve operational efficiency, particularly for venues that need to top up machines throughout the day. However, you must always check your local health and food safety regulations to ensure pre-batching is permitted in your area.

Pre-batching and storage guidelines

When pre-batching soft serve mix, it is essential to follow Good Management Practices (GMPs) to maintain food safety and product performance:

 - Use only clean, sanitised food-grade equipment (such as buckets, whisks, or hand blenders) dedicated exclusively to soft serve preparation

 - Store mix in food-safe containers with airtight lids

 - Once rehydrated, soft serve mix is treated as fresh dairy and must be stored refrigerated below 5°C (this applies to both dairy and non-dairy blends to ensure freshness and optimal performance)

 - All pre-batched mix must be used or discarded within 2–3 days

 - Do not freeze pre-batched soft serve mix

Following these guidelines helps ensure consistent product quality, food safety, and smooth machine operation.

As a general guide, soft serve or frozen yoghurt mix can remain in the machine for 2–3 days total, calculated from rehydration to discard. This is the maximum recommended timeframe to maintain product quality and food safety.

Can the mix stay in the machine overnight? Yes — only if your machine is set to standby mode and your local health regulations allow it.

Standby mode typically maintains the mix at 4–5°C, helping prevent spoilage and ensuring the product remains safe and ready for use the next day. If your machine does not have standby mode or if standby is not activated, the mix should not be left in the machine overnight, as temperature fluctuations can compromise both food safety and product quality.

Always refer to your machine manufacturer’s guidelines, as operating requirements can vary between models.

What happens if the machine is not put on standby overnight? If a machine has been left overnight without standby mode enabled, food safety and machine performance may be compromised. In this case: running a wash cycle to liquefy any remaining mix, discarding all remaining product, thoroughly cleaning and sanitising the machine and all removable parts, refilling the hopper with fresh mix before restarting.

Prompt action helps ensure hygiene, prevents downtime and protects equipment performance. To avoid this situation, consider using a closing checklist or setting end-of-day reminders to activate standby mode.

How long can mix be stored in different machine types?

 - Conventional machines: mix must be used or discarded within 2 days

 - Heat-treated machines: always follow the manufacturer’s guidelines

What is “re-run” mix and can it be reused? “Re-run” refers to mix that has been previously dispensed from the machine but not served. To reduce wastage, re-run mix may be collected in a clean, sanitised container and combined with fresh mix, provided:

 - Re-run does not exceed 40% of the total mix volume

 - The combined mix is used within the approved timeframes

 - All handling follows Good Management Practices (GMPs)

 - Local health regulations permit this practice

Frosty Boy Australia does not recommend the use of re-run mix.

Best practice guidelines for handling soft serve mix or re-run mix;

 - Confirm your local health code allows the practice

 - Follow Good Management Practices (GMPs) at all times

 - Set the machine to standby mode overnight

 - Use designated, food-safe equipment exclusively for soft serve preparation and storage

 - Sanitise all equipment and utensils (containers, whisks, etc.) before use
