"Anybody can do this, it's really easy. Just throw all your ingredients into the slow cooker and go to work.
"The best part is that when your friends eat it, they will be so impressed and think that you are a d*** good cook," says Ms Siew, who is in a relationship.
Her cut of choice is pork belly, although pork ribs and pork shoulder can be used as well.
Do not use sliced pork tenderloin, she says, as the lean cut will become tough after the long cooking.
Ingredients such as hard-boiled eggs, tau pok (beancurd puffs) and mushrooms can be added for a heartier meal, but Ms Siew focuses on the fatty meat for her meatloving friends.
There is no need to skim off the oil after the dish is cooked either, she says, drizzling the unctuous gravy onto steamed rice.
Her recipe has been refined over the years. She tried adding mirin and Coca-Cola to the braising liquid, before deciding on root beer.
"It gives a richer flavour and it is not overly sweet. I got the idea when I saw a lot of recipes online using Coca-Cola for cooking meats."
There is also no need to sear the meat before braising, she says, adding that she has done it and it does not make a significant difference to the finished dish.
Recipes in her repertoire include chap chye, a dish of braised vegetables; and a labour-intensive otah, which is a spicy fish mousse. She also makes popsicles, and shows The Sunday Times her lavender-infused yogurt popsicle, made with strawberries cooked in sugar.
She wants to learn how to make ayam buah keluak, but jokingly complains: "I feel so tired just reading the recipe."
Hokkien mee is also on her list, but she says: "I want to make it, but cooking the prawn stock is troublesome."
The self-taught cook makes it a point to read up on recipes and techniques before starting, as she recalls an incident from when she was 14.
"I was cooking pasta for my mum and I knew you had to add salt to the water. But I didn't know why. So I threw in way too much salt and every bite was salty," she says, laughing.
Now more accomplished, she whips up meals twice a week and enjoys hosting friends.
She says: "I like to see people being happy when they are eating. Cooking helps me to destress and is therapeutic."
