Test recipe: berry smoothie
This is a test article of the recipe type, written at a realistic length so the reading layout can be judged. It exercises the recipe card, the ingredients slot and the recipe structured data.
Some breakfasts ask for time and attention. This one asks for a blender and about five minutes. A berry smoothie is one of those recipes that most of us make without thinking, yet a few small choices decide whether it turns out thick, cold and bright or thin, warm and slightly grey. Here is a version for two glasses, with a scoop of unflavoured collagen powder stirred in, and a few notes on how to make it your own.
About this recipe
This smoothie is built on a simple ratio: roughly as much frozen fruit as liquid, plus something creamy to give it body. Frozen berries do two jobs at once, adding colour and keeping the drink cold without watering it down the way a lot of ice would. The banana brings natural sweetness and a smooth texture, and the yoghurt makes it feel more like a small meal than a juice.
The collagen powder is optional. If you already use an unflavoured powder in your morning coffee, a smoothie is an easy second home for it, because it disappears completely into the fruit. If you do not, simply leave it out; the recipe works just as well without it.
The quantities make two medium glasses. If you are making it just for yourself, halve everything, or make the full amount and keep the second glass in the fridge for later in the day. The recipe also scales up easily for a family breakfast, as long as your blender is large enough; work in batches rather than filling the jug to the brim.
The ingredients
Everything in the list is easy to find and keeps well, which makes this a good recipe for weekday mornings. Milk can be dairy or any plant-based drink you like; oat and soy drinks give the creamiest result. Natural yoghurt adds a gentle sourness that balances the sweetness of the fruit.
Choosing your berries
Bags of frozen mixed berries are the most practical choice, and they are often picked and frozen at their best. Blueberries give a deep purple colour, raspberries a brighter red and a few more seeds, and strawberries a milder, sweeter taste. In summer you can use fresh berries instead; just add a few ice cubes so the smoothie stays cold.
The oats are a small addition that makes the smoothie a little thicker and more filling. If you prefer a lighter drink, leave them out and add a splash more milk instead.
Honey or maple syrup is entirely optional. Ripe bananas and sweet berries are often enough on their own, so taste first and sweeten only if you feel the smoothie needs it.
Before you blend
A little preparation the evening before makes the morning easier. Many people keep a smoothie kit in the freezer: a bag with the berries and a sliced banana for one batch, ready to tip into the blender. All you have to add in the morning is the liquid, the yoghurt and the powder.
- A blender, either a jug blender or a sturdy hand blender with a tall beaker.
- A measuring jug or a glass with millilitre markings.
- Kitchen scales, or a cup measure if you prefer to work by volume.
- Two tall glasses, chilled in the fridge if you have the time.
If your banana is very ripe, peel it, break it into pieces and freeze it. Frozen banana makes the smoothie wonderfully thick, almost like soft ice cream.
Step-by-step tips
The method in the recipe card is short, but the order in which you add things to the blender matters more than you might think. Liquids go in first so the blades can turn freely; heavy frozen fruit goes in last so it is pushed down onto the blades.
- Start with the milk, then the yoghurt.
- Add the soft ingredients next, such as the banana and the oats.
- Put the frozen berries on top.
- Blend on a low setting first, then turn the speed up once everything moves.
- Add the powder at the end and blend only briefly.
If the blender struggles, stop, stir with a spatula and add a splash more milk. Avoid running it for too long, because the motor warms the drink. Taste before pouring: a little more honey if the berries are tart, a little more milk if it is too thick.
Variations
Once you know the basic ratio, the recipe is easy to change with the seasons or with whatever is in your kitchen. Keep the amount of frozen fruit roughly the same and swap the rest.
- Green: replace half of the berries with a handful of spinach and a few slices of cucumber.
- Tropical: use frozen mango and pineapple instead of berries, and coconut drink instead of milk.
- Chocolate: add a spoonful of cocoa powder and a few dates instead of honey.
- Spiced: add a pinch of cinnamon and a little grated ginger to the berry version.
For a version with more protein, our magazine has a recipe for a collagen protein shake built on the same idea.
Making it ahead
Smoothies are at their best straight from the blender, when they are cold and the colour is brightest. If you need to make one ahead, pour it into a jar with a tight lid, fill it to the top to leave as little air as possible, and keep it in the fridge until the next morning. Shake it well before drinking, since it will separate a little.
A smoothie kit in the freezer turns a busy morning into a two-minute job.
You can also freeze leftover smoothie in an ice-cube tray and add the cubes to your next batch instead of ice.
Another approach is to prepare everything except the liquid the night before: put the fruit, oats and yoghurt in the blender jug, cover it and keep it in the fridge. In the morning you only need to pour in the milk and press the button, which is about as quick as breakfast gets.
Serving ideas
Serve the smoothie in tall glasses with a few whole berries on top, or pour it into a bowl and turn it into a smoothie bowl with sliced fruit, a spoonful of nuts and a sprinkle of oats. Children often like it in small cups with a spoon, especially when it is thick.
A smoothie also travels well. Pour it into an insulated bottle and it will stay cold for a commute or a morning walk. Give the bottle a good shake before you drink, because the fruit settles over time.
