To make a smoothie, combine a measured amount of liquid with fruit and any other ingredients your recipe calls for, then blend until the texture suits you. Start with a small batch and adjust gradually. It is much easier to add another splash of liquid than to fix a jug that has become too watery.
You do not need a complicated recipe to learn the process. Once you understand how liquid, fruit and thicker ingredients work together, you can make useful adjustments without guessing every time.

Start with This Simple Smoothie Formula
For an ordinary fruit-and-yogurt smoothie, use the following as a starting point:
| Ingredient | Starting quantity | Purpose |
|---|---|---|
| Milk or a suitable alternative | 100–150 ml | Helps the ingredients blend |
| Fruit | About 100–150 g | Provides the main flavour |
| Plain yogurt | About 100 g | Adds body and changes the texture |
| Spice or flavouring | A small amount, optional | Adjusts the flavour |
These quantities are a starting formula, not a nutritional prescription. Different fruits, yogurts and appliances produce different results.
Begin at the lower end of the liquid range if your blender instructions allow it. Add more gradually if needed.
The mixture generally makes one modest smoothie, although the finished volume depends on the ingredients and how much air is incorporated during blending.
If you want to understand alternative ingredients before choosing a recipe, read our smoothie ingredients guide.
Choose Your Ingredients Before Switching on the Blender
Set everything out before you begin. This helps you check the quantities, avoid missing an ingredient and keep the process straightforward.
Choose one main fruit
For your first few attempts, use one fruit you already enjoy.
Banana gives a different result from berries, while mango behaves differently from watermelon. Using fewer ingredients makes it easier to understand those differences.
Fresh or frozen fruit may work, depending on the recipe. Check whether your appliance is designed to blend frozen ingredients and follow the food package’s preparation directions.
Pick a liquid that suits the recipe
Milk, an appropriate plant-based drink or water can each produce a different flavour and consistency.
If you use a packaged drink, check whether it is sweetened or flavoured. Vanilla-flavoured milk, for example, may change a recipe that was written for plain milk.
Choose an alternative that meets your dietary requirements rather than assuming all products are interchangeable.
Decide whether you want yogurt
Yogurt changes the texture and flavour. Plain yogurt lets you taste the fruit without introducing another strong flavour, while different products vary in thickness.
If your recipe does not use yogurt, follow that recipe’s quantities. Simply removing 100 g of yogurt from the formula above will change the finished result.
Keep optional additions simple
Cinnamon, cocoa, oats, seeds and nut butter can all change a smoothie. Begin with a small, measured addition and a clear reason for including it.
A recipe becomes difficult to troubleshoot when several extras go in at once.
A Basic Berry Smoothie to Practise With
This recipe gives you a straightforward way to practise measuring, blending and adjusting.
Ingredients
- 125 g berries, prepared according to package directions.
- 100 g plain yogurt.
- 100 ml milk or a suitable unsweetened alternative.
- Additional liquid, a tablespoon at a time, if needed.
Yield: One serving.
The taste will depend on the berries and yogurt you use. Choose ingredients suitable for your dietary needs and avoid any allergens.
Equipment
- A blender suitable for the ingredients.
- Kitchen scales or appropriate measuring equipment.
- A measuring jug.
- A glass or other serving container.
Instructions
- Read your blender’s loading instructions. Some appliances use a different ingredient order, particularly personal blenders with an inverted cup.
- Measure the ingredients. Keep the additional liquid separate so you can add it gradually.
- Load the blender as directed. Stay below its maximum fill line.
- Secure the lid or blade assembly. Check that everything is correctly attached.
- Blend using the appropriate setting. Follow the appliance’s operating instructions.
- Stop and check the mixture. If it needs more liquid, add a tablespoon and blend briefly again.
- Taste before changing the flavour. Decide whether it needs an adjustment.
- Pour and serve. Clean the equipment according to the manufacturer’s directions.
Do not place a spoon or other utensil near moving blades. Stop the appliance before opening it or adjusting ingredients.
Why the Amount of Liquid Matters
Liquid is one of the easiest parts of a recipe to adjust—and one of the easiest to overdo.
A large pour at the beginning can leave you with a thin drink. Adding more fruit to correct it increases the batch size, which may then require another adjustment.
Starting with a measured amount gives you more control.
If the mixture is too thick
Add a tablespoon of liquid, blend briefly and check again.
If the ingredients still do not move properly, stop and follow your blender’s troubleshooting instructions. Do not keep running an appliance that is struggling.
If the mixture is too thin
For the next batch, reduce the starting liquid.
For the current batch, you could add a small amount of an ingredient already included in the recipe, provided there is room in the blender and the appliance can handle it.
Remember that this makes a larger quantity. You may need to divide the finished mixture into more servings.
If you want a thinner drink
That is a preference, not a mistake. Add liquid gradually until you reach a consistency you enjoy.
The aim is a repeatable result that suits you.
Change One Ingredient at a Time
Once you have made the basic recipe, you can adapt it.
You might want a different fruit, a dairy-free version or a slightly thicker texture. Make one change at a time where practical.
For example:
- Keep the same quantities but try a different berry.
- Keep the fruit and yogurt the same but reduce the milk slightly.
- Keep the base recipe and add a small pinch of cinnamon.
This approach helps you understand what caused the difference.
Changing the fruit, liquid, yogurt and several extras together may produce something pleasant, but it makes the result harder to repeat.
Write down successful adjustments. A short note such as “125 g berries, 100 g yogurt, 80 ml milk” is more useful than trying to remember how much you poured.

Check the Serving Before Filling Your Glass
A blender jug is a mixing container, not a serving guide.
Some recipes make one portion. Others make two or more. Before pouring, check the recipe yield and the quantities used.
This becomes particularly relevant when you start adding ingredients freely. An extra banana, more yogurt and another splash of milk can turn the original serving into a much larger batch.
If you want to estimate the nutritional content, record the ingredients and divide the total by the number of servings you actually make.
Our smoothie calorie guide explains that process. Changing the ingredients or yield means the figures supplied with the original recipe may no longer apply.
Taste Before Adding Sweeteners
Fruit varies in sweetness, and packaged ingredients can introduce sweetness of their own.
Blend the original recipe first, then taste it.
If you regularly find a smoothie too sharp, you might prefer a different fruit combination or yogurt. If it is too sweet, check for sweetened liquids, flavoured yogurt or several sweet ingredients used together.
You do not have to fix every flavour problem by adding honey, syrup or another sweetener.
If you do add something, measure it. That helps you recreate the flavour and account for the full recipe.
Avoid These Common Blending Mistakes
Filling beyond the maximum line
Leave the space required by your appliance instructions. A recipe can be divided into smaller batches if necessary.
Using ingredients the blender cannot handle
Not every blender is suitable for large frozen pieces, ice or hard ingredients. Check before using them.
Adding several extras without measuring
A spoonful of this and a handful of that can change the flavour, texture and serving size. Start with the written recipe.
Running the blender when ingredients are stuck
Stop and follow the appliance instructions. Adding a suitable amount of liquid or preparing ingredients differently may help, but repeated running is not a substitute for checking the problem.
Expecting every smoothie to serve the same purpose
A small fruit drink and a deliberately planned breakfast preparation may contain quite different ingredients.
Consider what you are making and how you intend to use it. Our guide to whether smoothies are healthy explains why the whole recipe and serving matter more than the name.
Make Cleanup Part of the Method
A smoothie routine is easier to repeat when the blender is ready for the next use.
After serving:
- Follow the appliance’s cleaning instructions.
- Handle blades and removable parts carefully.
- Clean the lid, seals and cup as directed.
- Allow parts to dry appropriately before storage.
Do not assume every blender component is dishwasher-safe or that the motor unit can be immersed in water.
The few minutes spent on cleanup belong to the preparation routine just as much as measuring and blending.
Frequently Asked Questions
Can I make a smoothie with water?
Yes, when it suits the recipe. Water produces a different flavour and consistency from milk or yogurt-based combinations.
Start with a recipe designed around water if you want a clearer idea of the intended result.
Do I need ice?
No. Ice is optional and changes both temperature and texture. It can also dilute the drink as it melts.
Use it only if your blender is designed to handle it.
How long should I blend?
Follow your appliance instructions and the recipe. The time varies with the equipment, quantities and ingredients.
Check the result rather than relying on one universal blending time.
Can I double the recipe?
You can scale the ingredient quantities, but only if your appliance has sufficient capacity and is suitable for the mixture.
Do not exceed its fill limit. Making two separate batches may be more practical.
Can I leave out yogurt?
Use a recipe designed without it, or expect to adjust the quantities and texture. Removing an ingredient changes the balance of the original formula.
Does every smoothie need to be a meal replacement?
No. A smoothie can be a drink served alongside food. Its role depends on the recipe and your needs.
Do not treat a basic fruit smoothie as a complete meal simply because it is thick or fills a large glass.
Learn One Formula, Then Make It Your Own
Start with measured ingredients, follow your blender’s directions and adjust in small steps. Check the serving size and write down the version you enjoy.
Once the process feels familiar, experiment with another fruit or a different recipe.
You do not need to get every combination right on the first attempt. Learning what to change—and keeping track of what works—is how a simple recipe becomes your own dependable blend.
