Thai Tom Kha is a creamy and sweet, yet savory and slightly spicy soup that is on the comfort food list in our house. Literally translated, tom kha gai means “chicken galangal soup.” It’s traditionally made from chicken, lightly poached in a silky coconut milk broth, which has been infused with galangal (kha), lemongrass and lime leaves.

I’m making the traditional Tom Kha with a little twist of my own. I’m adding shrimp and garnishing with perfectly seared scallops. Both sea and bay scallops are delicious in this recipe. I wanted to sear my scallops instead of poaching them in the broth. The scallops at Heinen’s are just too amazing to poach – they are far better pan-seared. Using a spoon to cut through the caramelized edge will reveal the silky interior. When you taste the amazing, sweet, milky-smooth broth with a slight hint of heat, you will understand the process.

Making this soup authentically requires rounding up a few hard-to-find ingredients. Heinen’s stocks lemongrass and occasionally has a shipment of galangal. Lime leaves are a bit harder to find. Lime kaffir leaves are known for their amazing fragrance. While it’s often said that lime leaves simply can not be replaced in dishes that call for them, I often substitute lime peel in this soup when I can’t find them. It’s still delicious.

Another product used in this recipe is ghee. What is ghee? It’s a type of clarified butter. Whereas butter contains butterfat, milk solids and water, ghee is pure butterfat that’s cooked longer until all moisture is removed and the milk solids are caramelized and then filtered out. I love cooking scallops in ghee because it gives them a buttery flavor that holds up to high temperatures. Ghee is stable up to 480°F. Scallops are most delicious when they have a nice brown crust on either side and are just barely cooked through in the middle.

Galangal is often confused with ginger, but it’s actually an aromatic root with a tender peel and woody flesh. It does look slightly similar to ginger with similar spice notes, but the rich, earthy flavor of galangal is something that ginger cannot replicate. I recommend looking for younger galangal when shopping, which is best identified by its thinner peel.

Lemongrass is a culinary herb used in many dishes from soups to curries and even tea. Lemongrass imparts a beautiful lemon scent and flavor to anything it’s used in. Often sold in bunches, look for stalks that are clean, fragrant and free of soft spots. The leaves may be dry, but the stalk should be wet.

Ingredients on the Counter

As with all seafood, shrimp and scallops should smell sweet with a slight scent of brine (salty seawater). Fresh seafood should never smell fishy. The scallops and shrimp I picked up at Heinen’s were exactly as they should be.

Heinen's Grocery Store

By Heinen's Grocery Store

In 1929, Joe Heinen opened the doors of a small butcher shop on the east side of Cleveland, Ohio, aiming to establish himself as the city’s purveyor of quality meats. As customers came into Heinen’s new shop for their meat purchases, they began asking him to carry groceries as well. Joe added homemade peanut butter, pickles and donuts and by 1933, business had grown enough to include a line of produce and canned goods. Heinen’s Grocery Store was born.
