Authentic Thai cooking
A word about premade pastes in Thai households. Our cultural tradition is to create food from scratch, with the freshest ingredients, often plucked from our garden or purchased at the food markets.
I’ve yet to find a Thai person who uses premade paste for our beloved soup, instead, we prefer to gather fresh herbs and spices and pound them when we’re about to cook up a delicious meal. This cherished moment is a wonderful family time for us. In my family, our gatherings aren’t just about sharing meals, but also about cooking them with love and joy.

While we do make some pastes in advance, like green curry paste, red curry paste, and nam prik pao (Thai chili paste), when it comes to making tom yum soup, we prefer making it from scratch.
Whenever I visit Bangkok, I can see a similar fast-paced lifestyle to what I’ve seen in Europe. I truly hope that our Thai tradition of making food from scratch doesn’t fade away in a world that’s switching to a such a modern lifestyle. As for me, I’ll always cherish creating food from zero.
Ingredients

- Dried chilies – Together with their large counterparts, these sun-dried peppers are providing the paste with heat and a smoky depth.
- Shallots – Shallots add a subtle hint of sweetness.
- Garlic – Garlic enhances the paste with a pungent note and garlicky aroma.
- Lemongrass – Lemongrass is commonly used in Thai cuisine for adding a fresh flavor and citrusy aroma.
- Galangal – Galangal has a peppery, earthy flavor.
- Kaffir lime leaves – Kaffir lime leaves are aromatic and citrusy, contributing to the authentic Thai taste of this paste.
- Fish sauce – A key ingredient of Southeast Asian cuisine for adding a salty and umami flavor to dishes.
- Palm sugar – Palm sugar is a natural sweetener that adds an extra caramel-like flavor.
- Fresh lime juice – A tangy taste is one of the characteristics of the tom yum flavor.
