What Is Tom Rim?

Tom rim is a beloved Vietnamese dish where shrimp are caramelized in a savory, sweet, and slightly tangy sauce. The name “tom rim” translates to “simmered shrimp,” perfectly describing the cooking process. This dish is a staple in Vietnamese households, celebrated for its simplicity and ability to transform basic ingredients into a rich and flavorful meal.

The key to tom rim lies in the caramelized sauce, which coats the shrimp in a glossy, sticky layer. Made with fish sauce, sugar, and aromatic ingredients like garlic and shallots, the sauce perfectly balances sweet, salty, and umami flavors. As the shrimp cook, their natural sweetness melds with the sauce, creating a mouthwatering combination that pairs beautifully with steamed rice.

Tom rim is all about comfort and bold flavor packed in every bite. Its vibrant orange hue and irresistible aroma make it a standout dish on any dinner table, offering a true taste of Vietnamese home cooking.

Ingredients

To make tôm rim, we will need a mix of basic and flavorful ingredients that come together to create this Vietnamese classic. Here’s what we’ll need:

• Shrimp: 1 kg (2.2 lb) of fresh prawns or shrimp. You can leave the shells, heads, and legs on for added crunch and flavor, or opt to remove them if you prefer.
• Salt: 1 1/2 tsp, or adjust to taste.
• Sugar: 3 tbsp, to provide the caramelized sweetness.
• Chicken Bouillon Powder: 1 tbsp, for added depth of flavor.
• Fish Sauce: 3 tbsp, added towards the end to maintain its bold aroma and robust flavor.
• Dark Soy Sauce: 1 tsp, to enhance the dish’s color and richness.
• Garlic: 3 cloves, finely chopped for a savory base.
• Red Shallot (optional): 1, finely chopped to boost the flavor profile.
• Spring Onion (optional): 1 sprig, cut into segments for freshness and garnish.

Tools And Equipment

Preparing tom rim is a straightforward process that requires minimal but essential tools to ensure the best results. Here is a list of tools and their roles in creating this flavorful dish:

• Non-stick or cast iron skillet (medium-sized): Ideal for even heat distribution, allowing the shrimp to cook evenly and the caramel sauce to coat them perfectly. A skillet with high sides helps prevent splatters.
• Sharp knife and cutting board: These are crucial for finely chopping garlic, shallots, and optional spring onions. Precise chopping ensures the ingredients cook evenly and release their full flavor.
• Mixing spoon (wooden or silicone preferred): Gentle on the skillet’s surface and perfect for stirring the aromatic caramel sauce without scratching or disrupting the shrimp.
• Small heatproof bowl: Used for mixing the fish sauce, sugar, and soy sauce in advance for smoother integration while cooking.
• Tongs or slotted spoon: Ideal for handling shrimp during preparation and cooking, ensuring even coating and easy flipping.
• Measuring spoons and cups: Essential for maintaining the balance of flavors, from the sweetness of sugar to the saltiness of fish sauce.
• Rice cooker or pot: Preparing steamed rice, which is the classic pairing for tom rim, requires a reliable rice cooker or a sturdy pot for fluffy, evenly cooked rice.

A well-equipped kitchen makes the process seamless and ensures that your tom rim achieves the rich, glossy texture and bold Vietnamese flavors we all love. Always keep these tools within arm’s reach for efficient, enjoyable cooking.

Directions

Let’s dive into the step-by-step process of making tom rim, where we will transform simple ingredients into a stunning, caramelized shrimp dish. Follow along closely for the best results.

Prep The Ingredients

1. Prepare the Shrimp: Start with 1 lb of shrimp, deveined and butterflied. Use kitchen shears to cut down the back of each shrimp to the tail, then slit gently with a knife to open the shrimp without cutting through completely. Rinse under cold water and pat them dry with a paper towel.
2. Chop the Aromatics: Dice 1/2 an onion. Separate 3-4 green onions into white (chopped) and green (sliced) parts. Mince 2-3 cloves of garlic and, optionally, a small piece of ginger and 1-2 shallots.
3. Prep the Chili and Herbs: Thinly slice one birdseye chili (or your chili of choice) for heat. If using cilantro, chop a few sprigs for garnish.

Make The Sauce

1. Combine Ingredients: In a small bowl, mix 2-3 tablespoons of fish sauce, 1 tablespoon of dark soy sauce, and 1 tablespoon of brown sugar. Stir until the sugar dissolves.
2. Adjust the Flavor: Add 1/2 teaspoon of chicken bouillon powder and a pinch of ground black pepper for depth. Optionally, drizzle with 1/2 teaspoon of sesame oil for a nutty note. Set the sauce aside.

Cook The Tom Rim

1. Caramelize the Sugar: Heat a non-stick or cast iron skillet over medium heat. Add 1 tablespoon of sugar with a splash of water. Stir constantly until the sugar melts and turns an amber color. Be careful to avoid burning.
2. Add Aromatics: Quickly add the minced garlic, onions, and shallots to the caramel. Stir for 1-2 minutes until aromatic.
3. Cook the Shrimp: Place the prepared shrimp into the pan in a single layer. Cook for 2 minutes on each side until they turn pink and curl slightly.
4. Add the Sauce: Pour in the prepared sauce. Toss the shrimp to coat them evenly. Let the mixture simmer for 3-4 minutes, stirring occasionally until the sauce thickens and beautifully glazes the shrimp.

Final Touches

1. Taste and Adjust: Taste the dish and adjust seasoning with a bit more fish sauce or sugar if needed.
2. Garnish: Sprinkle the cooked shrimp with the sliced green onion tops, chili slices, and chopped cilantro (if using).
3. Serve: Serve the tom rim hot over steamed rice, letting the glossy, caramelized shrimp steal the show on your plate.

Tips For Success

To ensure our Tôm Rim comes out absolutely perfect, we need to focus on a few essential techniques and tips. These time-tested methods will help us capture that iconic caramelized flavor and texture the dish is celebrated for.

1. Marinate for Maximum Flavor

Marinating the shrimp is a non-negotiable step to infuse them with rich flavor. We recommend marinating the shrimp overnight in the fridge, using a blend of fish sauce, sugar, and optional aromatics like garlic or shallot. If time is limited, we can marinate them for at least 30 minutes, but overnight will yield the best results by helping the shrimp retain moisture and soak in every bit of seasoning.

2. Keep the Shells On

Keeping the shrimp shells on is a traditional technique that elevates the dish. The shells not only protect the meat from overcooking but also add a crunchy texture and allow the caramelized sauce to coat the exterior beautifully. This also enhances the umami profile of the dish and deepens the flavor as the shells absorb the sauce during cooking.

3. Perfect the Caramelization

The caramelization process is the most crucial step in achieving Tôm Rim’s signature glossy look and irresistible taste. As we caramelize sugar, patience is key. Use low to medium heat and stir until the sugar deepens into a golden brown hue. From there, the addition of liquids like fish sauce or the marinating juices will create a luscious, fragrant sauce. For a more intense flavor, some of us may choose to cook the caramelized sauce until it thickens and even slightly chars, adhering firmly to the shrimp.

4. Use Quality Ingredients

The simplicity of Tôm Rim calls for high-quality, fresh ingredients. Fresh shrimp will provide the cleanest, sweetest flavor, while a good-quality fish sauce and dark soy sauce will make all the difference in the depth of our final dish. Do not substitute brown sugar, as its complexity is essential to creating a balanced caramel base.

5. Control the Heat

Temperature control plays a significant role in the success of Tôm Rim. Start with medium heat to caramelize the sugar evenly. Once the shrimp are added, adjust the heat to low or medium-low to avoid burning the sauce since it thickens quickly. Stir gently but consistently to ensure every shrimp gets an even coat of sauce.

6. Serve Immediately

Tôm Rim is best enjoyed while hot, fresh off the stove. The sauce retains its glossy, sticky texture when freshly cooked. Serve it right away over a bed of steamed rice so that the warm, flavorful sauce seeps into the grains for a comforting, satisfying pairing.

Variations And Substitutions

When it comes to tom rim, there are a variety of ways to customize the dish without sacrificing its signature flavor. Whether you’re making adjustments due to ingredient availability or personal preference, here are some variations and substitutions to consider.

Shrimp Options

Traditionally, tom rim is made with shell-on, head-on shrimp. This type of shrimp enhances the depth of flavor and texture, as the head and shell contribute additional richness to the dish. However, if live, fresh shrimp are not readily available, headless shrimp are a great alternative. Using headless shrimp prevents the release of enzymes that can make the shrimp mushy and introduce an off odor.

Prefer peeled shrimp for a cleaner presentation or an easier dining experience? You can use shell-off shrimp as well, although they might lack some of the extra umami provided by the shells.

Caramel Sauce Substitutions

The foundation of tom rim’s irresistibly glossy finish lies in its caramel sauce, or nước màu. Made from sugar and water, this sauce provides the dish with its distinct smoky, sweet-savory flavor profile and amber hue. If you’re looking for an alternative, concentrated or reduced coconut water can stand in for traditional caramel. While this substitution requires more time to achieve the proper consistency, it introduces a subtle coconut fragrance that beautifully complements the shrimp.

Adjusting Saltiness with Fish Sauce

Fish sauce is integral to crafting the complex umami taste of tom rim. For those seeking a slightly less salty dish, reduce the amount of fish sauce and supplement with low-sodium soy sauce. This can tone down the saltiness while still preserving the bold savory flavor. Similarly, if fish sauce isn’t available, liquid aminos or a combination of diluted anchovy paste and soy sauce can work as substitutes.

Aromatic Additions

While garlic and shallots are core ingredients in the sauce, feel free to experiment with aromatics to customize the flavor. Adding finely sliced lemongrass or ginger can lend a fragrant and zesty note. For a touch of heat, include minced Thai chilies or crushed red pepper flakes.

Garnish Options

Traditionally, chopped spring onions or cilantro are used to garnish tom rim. However, you can swap these for fried shallots for extra crunch or fresh basil if you prefer a peppery herb finish. These small adjustments can make the dish even more visually appealing and flavorful.

Optional Sweetness Adjustments

Tom rim’s sweet-savory caramelized sauce is a hallmark of the dish. If you prefer a less sweet profile, simply reduce the sugar quantity. Alternatively, honey or palm sugar can replace granulated sugar, imparting a slightly richer or more earthy sweetness.

By experimenting with these substitutions and variations, we can adapt the traditional recipe of tom rim while preserving its charm and delicious essence.

Tom rim is more than just a dish; it’s a celebration of bold flavors, comforting aromas, and the joy of home cooking. With its vibrant appearance and irresistible taste, it’s no wonder this caramelized shrimp recipe holds a special place in Vietnamese cuisine.
