Boost Blast Mojito: Six Alcohol-Free Mojitos from One Base

Boost Blast Mojitos are £5 on our menu and there are six of them: Boost-A-Berry, Appletini, Mango Thunder, Lychee Me Up, PomJito and Pinely Charged. All of them are alcohol-free, all of them are built on the same base of mint, lime and fruit, and all of them are considerably better than the sugary “mocktail” most places hand you.

The reason they work is that they are built like a proper mojito rather than a squash. Mint is pressed, not shredded. Lime is used generously. And the fruit is there to give body, not just sweetness. Once you have the method, all six flavours are the same drink with a different fruit in it.

Five minutes per glass, no cooking beyond a two-minute sugar syrup, and they scale into a jug easily for a barbecue or a party.

Why this recipe works

• The mint is pressed, not muddled to death. Six or eight leaves pressed firmly against the bottom of the glass a few times release the aromatic oils. Grinding them shreds the leaf and releases chlorophyll, which tastes bitter and grassy.
• Fresh lime juice, not cordial. Half a lime per glass. Lime cordial is sweet without being sharp, and sharpness is the whole point of a mojito.
• Simple syrup instead of granulated sugar. Sugar does not dissolve in a cold drink. A liquid syrup sweetens evenly and lets you adjust in small amounts.
• Crushed ice, not cubes. Crushed ice chills faster and holds the mint and fruit in suspension so the drink looks alive rather than settled.
• Soda water added last, over a spoon. This keeps the carbonation, which is what stops an alcohol-free drink feeling flat and thin.
• Fruit purée rather than juice. Purée gives the body that alcohol would normally provide. Juice alone makes the drink taste watery.

Ingredient notes

Fresh mint. Spearmint, the ordinary supermarket kind. Buy it as a growing pot rather than a packet if you make these often — it lasts weeks on a windowsill and works out much cheaper. Use the leaves, not the stalks, which are bitter.

Limes. You need real ones. Roll them firmly on the worktop before cutting to get more juice out, and use the wedges in the glass as well as the juice.

Simple syrup. Equal weights of sugar and water, warmed until the sugar dissolves, then cooled. It takes two minutes and keeps in the fridge for a month. Any bar has a bottle of it and there is no substitute.

Fruit. Fresh or frozen both work. Frozen fruit is often better value and blends into a purée more easily straight from the freezer. For lychee, tinned lychees blitzed with a little of their syrup is the best route.

Soda water. Cold, and freshly opened. Sparkling water works. Tonic changes the drink because of its bitterness, which is interesting with pomegranate and apple but wrong with mango.

Pomegranate juice. For PomJito, use 100 per cent pomegranate juice, not a juice drink. It is sharp and tannic enough to stand up to the mint.

Substitutions and variations

All six are on our menu, and each one is the same base with a different fruit.

Boost-A-Berry. Strawberry. Muddle two or three halved strawberries in with the mint and lime. The most popular with children.

Appletini. Apple. Cloudy apple juice plus a few thin slices of green apple, and a little extra lime to keep it sharp.

Mango Thunder. Mango. Thick mango purée. The sweetest of the six, so cut the syrup back.

Lychee Me Up. Lychee. Blitzed tinned lychees, with two whole ones dropped in the glass.

PomJito. Pomegranate. Pomegranate juice with a spoonful of fresh seeds, which look excellent and give you something to chew.

Pinely Charged. Pineapple. Pineapple juice or purée with a wedge on the rim. Sharp and very refreshing.

Make it a jug. Multiply by six, press the mint in the jug with the lime and syrup, add the fruit and ice, and top with soda at the table.

Add popping boba. Two tablespoons in the bottom of the glass turns it into something closer to our Signature Sips.

Step-by-step guidance

The full method is in the recipe card below. Four small details do most of the work.

Pressing the mint. Put the leaves in the bottom of the glass with the lime juice and syrup. Press down firmly with the end of a rolling pin or a muddler five or six times, twisting slightly. You want the leaves bruised and glossy and the drink smelling strongly of mint. Stop there. If the leaves are torn into small dark pieces, you have gone too far.

Building in layers. Mint, lime and syrup first, then the fruit or purée, then crushed ice packed in firmly, then soda. Building in this order means the flavour is distributed as the soda travels down through the glass.

Crushing ice without a machine. Put cubes in a clean tea towel, fold it over and hit it with a rolling pin. Twenty seconds and you have crushed ice. It is more satisfying than it should be.

Finishing. Pour the soda down the side of the glass over the back of an upside-down spoon. Give it one slow lift with a long spoon from the bottom. Then a fresh mint sprig on top — slap it between your palms first, which releases the oils and is what makes the drink smell right as you lift it.

Professional tips

• Taste before the soda goes in. It should be a little too sharp and a little too sweet at that stage.
• Use a tall glass and fill it properly with ice. A half-empty glass of ice gives you a warm, dilute drink in three minutes.
• Keep a bottle of simple syrup in the fridge door. It turns a five-minute drink into a two-minute one.
• Slap the garnish mint, never chop it. Chopped mint looks brown within a minute.
• Roll the limes hard on the worktop before cutting. You will get noticeably more juice.
• If you are making a round of six, do all the pressing in a jug rather than six glasses. Much faster and more consistent.

Troubleshooting

Problem	Likely cause	Solution	Prevention
Drink tastes bitter and grassy	Mint was ground rather than pressed	Strain it into a fresh glass and add more syrup and lime	Press firmly five or six times and stop
Tastes like sweet water	Not enough lime, or fruit juice used instead of purée	Add fresh lime juice and a spoonful of purée	Half a lime per glass and a thick purée for body
Flat and lifeless	Soda poured straight in, or stirred hard	Top up with fresh soda over the back of a spoon	Pour down the side and stir once, slowly
Too sweet	Sweet fruit plus full syrup	More lime juice and more soda	Cut the syrup back for mango, lychee and strawberry
Gritty texture	Granulated sugar used instead of syrup	Nothing to do once built	Always use a liquid simple syrup in cold drinks
Warm within minutes	Not enough ice, or a room-temperature glass	Add more crushed ice	Chill the glass and pack the ice in firmly

What to serve with it

These do their best work against heat and salt. A PomJito next to Demon wings, or a Mango Thunder with chilli oil beef ramen, is a genuinely good pairing rather than just a drink on the side.

They are also the most useful thing on this site if you are hosting and someone is not drinking. Made in jugs, they look like a proper cocktail and nobody feels short-changed. For creamier options, look at our Coconut Cloud, and there are more in our bubble drinks recipes.

Storage and reheating

Build these to order. A mojito that has sat for fifteen minutes is a glass of minty water.

What you can make ahead is the base. Press the mint with the lime juice and syrup in a jug, add the fruit purée, and keep it covered in the fridge for up to 24 hours. It will darken slightly but the flavour holds. Add ice and soda to order.

Simple syrup keeps in a sealed bottle in the fridge for up to a month. Fruit purée keeps for three days in the fridge, or freeze it in an ice cube tray for up to three months and drop the cubes straight into the glass.

Fresh mint keeps best standing in a glass of water on the worktop, like a bunch of flowers, loosely covered with a bag.

Frequently asked questions

Is a virgin mojito just a mojito without rum?

Nearly, but not quite. Without alcohol you lose body and a little sharpness, which is why this version uses fruit purée rather than juice and a full half lime per glass. Straight rum-free mojitos usually taste thin.

Do I need a muddler?

No. The end of a rolling pin, the handle of a wooden spoon or a pestle all work. What matters is pressing rather than grinding.

Can I make these ahead for a party?

Yes. Make the mint, lime, syrup and fruit base in a jug up to a day ahead. Keep it in the fridge and add ice and soda as you pour. This is how bars manage a busy service.

How do I crush ice without a machine?

Wrap cubes in a clean tea towel and hit them with a rolling pin for about twenty seconds. A blender will also do it, but it tends to produce slush rather than crushed ice.

Can I use bottled lime juice?

It will work but it tastes noticeably duller, and you lose the aroma from the peel oils. Fresh limes are worth it here more than in almost any other drink.

Are these suitable for children?

Yes, they contain nothing but fruit, mint, lime, sugar and soda water. You may want to cut the lime back slightly for younger children.

Which is the best one to start with?

Boost-A-Berry if you like things sweet, PomJito if you like things sharp. Those two are the extremes of the range and everything else sits between them.
