Chef K is a celebrity private chef, entrepreneur, and content creator. For years, Khristianne Uy, known as Chef K, has worked as a private chef for household names and is now also a content creator. Unlike her celebrity clientele, Chef K said she makes her Instagram and TikTok recipe videos with a single mom struggling to make ends meet in mind. However, if you want to splurge on high-quality ingredients, these are the items Chef K said are worth spending extra on — and the ones you should buy cheaply. Extra-virgin olive oil has a lower smoke point than regular olive oil and high-heat avocado oil, making it more suitable for drizzling on salads or making dips.
