Two Sisters’ Smoothie’s aesthetic drinks are the ultimate flavour bombs with a local twist

Every weekend, a house in one of Kembangan’s landed residential areas throws its gates wide open for business, ready to welcome anyone looking for a rich, velvety smoothie.

Since December 2024, sisters-in-law Lew Su Ling, 31, and Lydia Batricia, 23, have been whipping up ice-cold fruity blends from the comfort of Lydia’s family home in Frankel Close.

Two Sisters’ Smoothie has all the simplicity and charm of a modern-day lemonade stand. Su Ling and Lydia’s “smoothie bar” is a foldable table draped with a red-and-white checkered sheet, on top of which their equipment and ingredients lie.

Their “dining area” is a bunch of camping chairs on the house’s front porch, where customers hang out. Homemade posters, tastefully designed, are stuck onto the walls with Blu Tack. They showcase some of the pair’s creations, such as the crowd-favourite strawberry matcha smoothie.

Two Sisters’ Smoothie may have a laid-back, informal way of operating, but they take their smoothies very seriously. Each drink was first conceptualised in Lydia’s bedroom, then subjected to months of R&D, until they hit the right spot.

It took much experimenting for Su Ling and Lydia to go from total novice to creative expert — all simply to understand what makes a good smoothie.

“This was the part that we had a lot of trouble with,” Lydia says. “Our main priority was getting that thick consistency. We had to put in lots of frozen fruits and the right amount of ice, and make sure that it’s not too icy tasting, while having that velvety smooth flavour to it.”

Gap in the market

Su Ling, 31, works full-time in human resources, but had always wanted to try her hand at running a business. So did Lydia, a 23-year-old university student studying supply chain management. Watching her parents work hard to build a meaningful business from the ground up inspired her to also venture out on her own.

It turned out that she did not need to go at it alone. Her brother — Su Ling’s husband – saw the entrepreneurial spark in both women and encouraged them to pursue their interest together.

Two Sisters’ Smoothie came about because the pair noticed that popular smoothie places in Singapore, such as Boost, don’t cater much to local taste buds. They saw an opportunity to incorporate fruits such as mandarin oranges and lychee, and experiment with others, including papaya.

“We realised that there aren’t a lot of these fruit combinations in the current market, so we decided to try something like this, since we enjoy it,” says Lydia.

They took some inspiration from Erewhon, an upscale grocery in Los Angeles. Its US$20 (or S$26.80) Hailey Bieber Strawberry Glaze skin smoothie went viral on TikTok in 2023.

Like Erewhon, Two Sisters’ Smoothie put much thought into making each drink Instagram- and TikTok-worthy. Its menu caters to different preferences, too — customers can choose to have apple juice, coconut water, or almond milk as their base, depending on whether they would like their drink to be more light and refreshing, or creamy. Additional toppings include yakult cream, cornflakes, and oreo bits, for 90 cents.

Prices range from S$5.90 to S$7.90, and the menu rotates every two months. Besides the seasonal special strawberry matcha (S$7.50), popular options include The Islander (mango, pineapple, banana, charcoal, yoghurt, mango jam) and Strawberry Glaze (strawberry, banana, yogurt, strawberry jam). Say Cheezz, their lychee-inspired twist with oranges, is also a refreshing boost. The drinks cost S$5.90 for a medium, and S$6.90 for a large.

The jams, in particular, give a really interesting texture and bite to the drink. Two Sisters’ Smoothies’ jams are homemade, fresh for the weekend, because Su Ling and Lydia wanted to keep them free of preservatives and low in sugar.

The pair has also whipped up a seasonal pistachio smoothie, which combines dates, banana, yoghurt, and cornflakes. A medium cup goes for S$6.90, while a large one costs S$7.90.

The business has gained traction on social media as more people catch on to the funky and eye-catching drinks. “We’re definitely very blessed to have influencers and the media featuring us and helping us to share that we exist,” Su Ling says.

More customers have since visited them, leading the duo to expand their workstation to two tables, and two blenders instead of one, so that they can accommodate more orders, says Su Ling. About 100 smoothies are sold every weekend.

A community from around and afar

When Two Sisters’ Smoothie first launched back in December, Su Ling and Lydia went door-to-door to hand out flyers and tell their neighbours to pop by for a drink. They hung up a banner on the wall outside their house and built an A-Frame sign with a poster just outside their gates.

Nowadays, neighbours pop by without needing as much prompting. “It’s a good way for us to really connect with our community. We don’t really get to interact with them much – only those people who live in this lane,” says Lydia.

The sisters have even chanced upon neighbours who were doing a yard sale for charity, and who make margaritas on the side. They bonded over their respective ventures and got into an impromptu discussion about blenders, Su Ling says with a laugh.

What really surprised the sisters, though, were the people who could come from afar. One of their regulars would drive 30 minutes from Sembawang for their smoothie fix, including their favourite The Islander.

“They did a grab-and-go the first few times, then they asked their friends to come and they just chilled around. They brought their own camping chairs!” says Su Ling.

The sisters’ front porch can seat about 10 to 20 people comfortably. The only unfortunate thing is that, despite the shelter, the rain does get in quite easily, when the weather turns especially bad.

That said, a self-pickup service is available for those who prefer to have their smoothies elsewhere, or after operating hours. Su Ling and Lydia have also prepared drinks for bulk weekday orders from a tuition centre, and had pop-ups at fitness centres, such as BFT.

Two Sisters’ Smoothie joins a growing trend of home-based F&B businesses in Singapore. Lydia’s parents were concerned about safety and privacy at first, but they have been supportive, especially after witnessing the warmth of the community. They have also found ways to help with various aspects of the business, such as advising how to plan finances, and sourcing for ingredients.

Now that they have gained a bit of a following, Su Ling and Lydia are excited to experiment with more fruit combinations for their drinks. We had a taste of their upcoming durian smoothie (not yet on the menu), and with how rich and luscious it was, we have a feeling it will be a hit.

The sisters are also considering adding some food to the menu. “We were thinking of what actually pairs well with smoothies. Maybe not too soon, but we are in the works of having bakes in our smoothies,” says Lydia.

Smoothie experts – and they bake, too?

“We try!” Su Ling laughs.
